| 1 | The state-of-the-art synthetic strategies for SAPO-34 zeolite catalysts in methanol-to-olefin conversion显示文摘Methanol-to-olefin(MTO)conversion has proven to be one of the most successful non-petrochemical routes for producing light olefins.Silicoaluminophosphate(SAPO)zeolite SAPO-34 is one of the best industrial catalysts for MTO conversion,but suffers from rapid deactivation due to the inherent diffusion bottleneck limited by the narrow eight-ring pore openings.To improve the MTO performance,considerable synthetic efforts have been devoted to decrease the crystal size of zeolites or introduce secondary larger pores in zeolite crystals to form hierarchical structures.This review mainly focuses on presenting the state-of-the-art synthetic strategies for nanosized and hierarchical SAPO-34 catalysts with excellent MTO performance.Furthermore,the industrialization of SAPO-34 catalysts for the MTO reaction,and some current problems and future prospects for the synthesis of SAPO-34 catalysts,are also pointed out.We expect that this review can not only shed some light on the preparation of SAPO-34 catalysts,but also stimulate the future development of high-performance SAPO-34 catalysts to meet the increasing demands of the chemical industry. | Qiming Sun Zaiku Xie Jihong Yu | 2018 | National Science Review2018，5，4： | 22 |
| 2 | Review on photocatalytic and electrocatalytic artificial nitrogen fixation for ammonia synthesis at mild conditions: Advances,challenges and perspectives显示文摘The ammonia synthesis from nitrogen and water under ambient conditions is one of the most inviting but challenging reaction routes.Although nitrogen is abundant in the atmosphere and the ammonia synthesis reaction is exothermic on the thermodynamics,the conversion of N2 to ammonia is actually hard to proceed owing to the chemical inertness and stability of N2 molecules.In industry,ammonia synthesis is carried out by the Haber-Bosch process under harsh conditions (300-500 ℃,20-30 MPa) associated with the requirement of substantial energy input and the enormous emission of greenhouse gases (e.g.,CO2).Recently,a growing number of studies on photo(electro)catalytic and electrocatalytic nitrogen reduction reaction (NRR) in aqueous solution have attracted extensive attention,which holds great promise for nitrogen fixation under room temperature and atmospheric pressure.However,the very low efficiency and ambiguous mechanism still remain as the major hurdles for the development of photochemical and electrochemical NRR systems.Here we provide an overview of the latest progresses,remaining challenges and future prospects in photocatalytic and electrocatalytic nitrogen fixation.Moreover,this review offers a helpful guidance for the reasonable design of photocatalysts and electrocatalysts towards NRR by combining theory predictions and experiment results.We hope this review can stimulate more research interests in the relatively understudied but highly promising research field of NRR. | Xiaolan Xue Renpeng Chen Changzeng Yan Peiyang Zhao Yi Hu Wenjun Zhang Songyuan Yang Zhong Jin | 2019 | Nano Research2019，12，6： | 20 |

| 4 | Theoretical understanding of the stability of single-atom catalysts显示文摘As a new frontier,the rapid development of single-atom catalysts (SACs)in heterogeneous catalysis has attracted extensive attention since the concept of singleatom catalysis was first coined in 2011 [1,2].Supported metal single atoms usaally possess unique chemical and physical properties and have a special local chemical environment that is distinctly different from conventional supported nanoparticles and metal catalysts. Studies in the past several years have shown four main advantages of SACs: high selectivity,possibly high stability, high atomic efficiency and tunable high activity,as shown in Fig.1.For efficiency. | Jin-Cheng Liu Yan Tang Yang-Gang Wang Tao Zhang Jun Li | 2018 | National Science Review2018，5，5： | 15 |
| 5 | Single-atom catalyst: a rising star for green synthesis of fine chemicals显示文摘The green synthesis of fine chemicals calls for a new generation of efficient and robust catalysts. Single-atom catalysts(SACs), in which all metal species are atomically dispersed on a solid support, and which often consist of well-defined mononuclear active sites, are expected to bridge homogeneous and heterogeneous catalysts for liquid-phase organic transformations. This review summarizes major advances in the SAC-catalysed green synthesis of fine chemicals in the past several years, with a focus on the catalytic activity, selectivity and reusability of SACs in various organic reactions. The relationship between catalytic performance and the active site structure is discussed in terms of the valence state, coordination environment and anchoring chemistry of single atoms to the support, in an effort to guide the rational design of SACs in this special area, which has traditionally been dominated by homogeneous catalysis.Finally, the challenges remaining in this research area are discussed and possible future research directions are proposed. | Leilei Zhang Yujing Ren Wengang Liu Aiqin Wang Tao Zhang | 2018 | National Science Review2018，5，5： | 15 |
| 6 | CO_(2) utilization: Developments in conversion processes显示文摘Carbon dioxide capture,utilization and storage(CCUS)eincluding conversion to valuable chemicals-is a challenging contemporary issue having multi-facets.The prospect to utilize carbon dioxide(CO_(2))as a feedstock for synthetic applications in chemical and fuel industries-through carboxylation and reduction reactions-is the subject of this review.Current statute of the heterogeneously catalyzed hydrogenation,as well as the photocatalytic and electrocatalytic activations of conversion of CO_(2) to value-added chemicals is overviewed.Envisaging CO_(2) as a viable alternative to natural gas and oil as carbon resource for the chemical supply chain,three stages of development;namely,(i)existing mature technologies(such as urea production),(ii)emerging technologies(such as formic acid or other single carbon(C1)chemicals manufacture)and(iii)innovative explorations(such as electrocatalytic ethylene production)have been identified and highlighted.A unique aspect of this review is the exploitations of reactions of CO2 ewhich stems from existing petrochemical plants-with the commodity petrochemicals(such as,methanol,ethylene and ethylene oxide)produced at the same or nearby complex in order to obtain value-added products while contributing also to CO_(2) fixation simultaneously.Exemplifying worldwide ethylene oxide facilities,it is recognized that they produce about 3 million tons of CO2 annually.Such a CO_(2) resource,which is already separated in pure form as a requirement of the process,should best be converted to a value-added chemical there avoiding current practice of discharging to the atmosphere.The potential utilization of CO_(2),captured at power plants,should also been taken into consideration for sustainability.This CO_(2) source,which is potentially a raw material for the chemical industry,will be available at sufficient quality and at gigantic quantity upon realization of on-going tangible capture projects.Products resulting from carboxylation reactions are obvious conversions.In addition,provided that enough supply of energy from non-fossil resources,such as solar[1],is ensured,CO_(2) reduction reactions can produce several valuable commodity chemicals including multi-carbon compounds,such as ethylene and acrylic acid,in addition to C1 chemicals and polymers.Presently,there are only few developing technologies which can find industrial applications.Therefore,there is a need for concerted research in order to assess the viability of these promising exploratory technologies rationally. | Erdogan Alper Ozge Yuksel | 2017 | Petroleum2017，3，1： | 13 |
| 7 | Encapsulating soluble active species into hollow crystalline porous capsules beyond integration of homogeneous and heterogeneous catalysis显示文摘Homogeneous molecular catalysts and heterogeneous catalysts possess complementary strengths,and are of great importance in laboratory/commercial procedures.While various porous hosts,such as polymers,carbons,silica,metal oxides and zeolites,have been used in an attempt to heterogenize homogeneous catalysts,realizing the integration of both functions at the expense of discounting their respective advantages,it remains a significant challenge to truly combine their intrinsic strengths in a single catalyst without compromise.Here,we describe a general template-assisted approach to incorporating soluble molecular catalysts into the hollow porous capsule,which prevents their leaching due to the absence of large intergranular space.In the resultant yolk(soluble)–shell(crystalline)capsules,the soluble yolks can perform their intrinsic activity in a mimetic homogeneous environment,and the crystalline porous shells endow the former with selective permeability,substrate enrichment,size-selective and heterogeneous cascade catalysis,beyond the integration of the respective advantages of homogeneous and heterogeneous catalysts. | Guorui Cai Meili Ding Qianye Wu Hai-Long Jiang | 2020 | National Science Review2020，7，1： | 12 |
| 8 | A Facile Synthesis of Monodisperse Au Nanoparticles and Their Catalysis of CO Oxidation显示文摘Monodisperse Au nanoparticles(NPs)have been synthesized at room temperature via a burst nucleation of Au upon injection of the reducing agent t-butylamine-borane complex into a 1,2,3,4-tetrahydronaphthalene solution of HAuCl4·3H2O in the presence of oleylamine.The as-synthesized Au NPs show size-dependent surface plasmonic properties between 520 and 530 nm.They adopt an icosahedral shape and are polycrystalline with multiple-twinned structures.When deposited on a graphitized porous carbon support,the NPs are highly active for CO oxidation,showing 100%CO conversion at-45°C. | Sheng Peng Youngmin Lee Chao Wang Hongfeng Yin Sheng Dai Shouheng Sun | 2008 | Nano Research2008，1，3： | 11 |
| 9 | Heterogeneous molecular catalysts for electrocatalytic CO2 reduction显示文摘This review provides an overview of the literature regarding heterogeneous molecular catalysts for electrochemical CO2 reduction (ECR).Fundamental aspects of the science,including aggregation,electrochemical rate laws,and electrode-catalyst electronic coupling,are discussed to provide a solid foundation on which to design experiments and interpret results.Mechanistic aspects of ECR are presented based on electrokinetic and spectroscopic measurements as well as density functional theory (DFT) calculations.Consensus is improving for electrokinetic measurements,but the redox state of the metal center under reaction conditions and DFT reaction pathways lack agreement in the literature.Concerning the tunable aspects of the molecular catalyst,the impacts of the metal center,ligand substituents,and electrode support on the activity and selectivity toward ECR are presented with an emphasis on those studies that controlled for aggregation and minimized mass-transport limitations.Extended three-dimensional (3D) structures such as polymers,metal-organic frameworks (MOFs),and covalent-organic frameworks (COFs) are discussed as highly tunable architectures that begin to mimic the catalytic pockets of enzyme active sites.To achieve the full potential of these catalysts,design principles must emerge based on a combination of deconvoluting measurements to extract intrinsic catalyst properties and more reliable theoretical calculations to predict reaction pathways. | Nathan Corbin Joy Zeng Kindle Williams Karthish Manthiram | 2019 | Nano Research2019，12，9： | 10 |
| 10 | Significantly enhanced piezo-photocatalytic capability in BaTiO_(3) nanowires for degrading organic dye显示文摘Over the last several years,piezo-photocatalytic effect was intensively investigated for a facile,effective and promising protocol to sewage treatment and environmental remediation.The research on the integration of piezocatalytic and photocatalytic process on lead-free ferroelectric materials is highly demanded to further push this field forward.In this work,BaTiO_(3) nanowires(BT NWs)were fabricated by a two-step hydrothermal method.The degradation of organic dye(methyl orange,MO)aqueous solution(5 mg L^(-1))by integrating photocatalysis with the piezoelectric-like effect under UV light radiation and ultrasonic vibration was investigated.The decomposition ratio reaches up to ~98.17%(at 80 min),which is around 1.28 and 2.24 times of the sole piezocatalysis and photocatalysis process,respectively.The intermediate product of hydroxyl radical(·OH)and superoxide radical(·O_(2)^(-))was detected and quantified by radical trapping experiments,to illustrating their key role in degrading MO molecules.In addition,we carried out sequential cycles to evaluate the cycling stability and usage durability of catalysts and a reduction of ~15% in the efficiency was observed after four cycles.This work provides a promising paradigm for the further development of piezo-photocatalytic materials and target applications in environmental field. | Xiaofang Liu Longyin Xiao Yong Zhang Huajun Sun | 2020 | Journal of Materiomics2020，6，2： | 10 |
| 11 | Recent advances in ionic liquids-based hybrid processes for CO_(2) capture and utilization显示文摘CO_(2) capture and utilization(CCU)is an effective strategy to mitigate global warming.Absorption,adsorption and membranes are methods used for CO_(2) separation and capture,and various catalytic pathways have also been developed for CO_(2) utilization.Although widely researched and used in industry,these processes are energy-intensive and this challenge needs to be overcome.To realize further optimization,novel materials and processes are continuously being developed.New generation materials such as ionic liquids(ILs)have shown promising potential for cost-effective CO_(2) capture and utilization.This study reviews the current status of ILs-based solvents,adsorbents,membranes,catalysts and their hybrid processes for CO_(2) capture and utilization.The special properties of ILs are integrated into new materials through hybridization,which significantly improves the performance in the process of CCU. | Shaohan Lian Chunfeng Song Qingling Liu Erhong Duan Hongwei Ren Yutaka Kitamura | 2021 | Journal of Environmental Sciences2021，33，1： | 9 |
| 12 | Methanation of carbon dioxide:an overview显示文摘Although being very challenging,utilization of carbon dioxide(CO_(2))originating from production processes and flue gases of CO_(2)-intensive sectors has a great environmental and industrial potential due to improving the resource efficiency of industry as well as by contributing to the reduction of CO_(2) emissions.As a renewable and environmentally friendly source of carbon,catalytic approaches for CO_(2) fixation in the synthesis of chemicals offer the way to mitigate the increasing CO_(2) buildup.Among the catalytic reactions,methanation of CO_(2) is a particularly promising technique for producing energy carrier or chemical.This article focuses on recent developments in catalytic materials,novel reactors,and reaction mechanism for methanation of CO_(2). | Wei WANG Jinlong GONG | 2011 | Frontiers of Chemical Science and Engineering2011，5，1： | 9 |
| 13 | Immobilization of functional nano-objects in living engineered bacterial biofilms for catalytic applications显示文摘Nanoscale objects feature very large surface-area-to-volume ratios and are now understood as powerful tools for catalysis,but their nature as nanomaterials brings challenges including toxicity and nanomaterial pollution.Immobilization is considered a feasible strategy for addressing these limitations.Here,as a proof-of-concept for the immobilization of nanoscale catalysts in the extracellular matrix of bacterial biofilms,we genetically engineered amyloid monomers of the Escherichia coli curli nanofiber system that are secreted and can self-assemble and anchor nano-objects in a spatially precise manner.We demonstrated three scalable,tunable and reusable catalysis systems:biofilm-anchored gold nanoparticles to reduce nitro aromatic compounds such as the pollutant p-nitrophenol,biofilm-anchored hybrid Cd0.9Zn0.1S quantum dots and gold nanoparticles to degrade organic dyes and biofilm-anchored CdSeS@ZnS quantum dots in a semi-artificial photosynthesis system for hydrogen production.Our work demonstrates how the ability of biofilms to grow in scalable and complex spatial arrangements can be exploited for catalytic applications and clearly illustrates the design utility of segregating high-energy nano-objects from injury-prone cellular components by engineering anchoring points in an extracellular matrix. | Xinyu Wang Jiahua Pu Yi Liu Fang Ba Mengkui Cui Ke Li Yu Xie Yan Nie Qixi Mi Tao Li Lingli Liu Manzhou Zhu Chao Zhong | 2019 | National Science Review2019，6，5： | 9 |

| 16 | Synthesis, isolation and characterization of methyl levulinate from cellulose catalyzed by extremely low concentration acid显示文摘A direct synthesis of methyl levulinate from cellulose alcoholysis in methanol medium under mild condition(180 210 C)catalyzed by extremely low concentration sulfuric acid(0.01 mol/L)and the product isolation were developed in this study.Effects of different process variables towards the catalytic performance were performed as a function of reaction time.The results indicated that sulfuric acid concentration,temperature and initial cellulose concentration had significant effects on the synthesis of methyl levulinate.An optimized yield of around 50%was achieved at 210 C for 120 min with sulfuric acid concentration of 0.01 mol/L and initial cellulose concentration below 100 g/L.The resulting product mixture was isolated by a distillation technique that combines an atmospheric distillation with a vacuum distillation where n-dodecane was added to help distill the heavy fraction.The light fraction including mainly methanol could be reused as the reaction medium without any substantial change in the yield of methyl levulinate.The chemical composition and structural of lower heavy fraction were characterized by GC/MS,FTIR,1H-NMR and13C-NMR techniques.Methyl levulinate was found to be a major ingredient of lower heavy fraction with the content over 96%.This pathway is efficient,environmentally benign and economical for the production of pure levulinate esters from cellulose. | Hui Li Lincai Peng Lu Lin Keli Chen Heng Zhang | 2013 | Journal of Energy Chemistry2013，22，6： | 9 |

| 18 | Fabrication and characterization of Fe_3O_4@SiO_2@TiO_2@Ho nanostructures as a novel and highly efficient photocatalyst for degradation of organic pollution显示文摘In this work we synthesize a novel and highly efficient photocatalyst for degradation of methyl orange and rhodamine B. In addition, a new method for synthesis of Fe_3O_4@SiO_2@TiO_2@Ho magnetic core-shell nanoparticles with spherical morphology is proposed. The crystal structures, morphology and chemical properties of the as-synthesized nanoparticles were characterized using Fourier transform infrared spectroscopy(FT-IR), scanning electron microscopy(SEM), transmission electron microscopy(TEM), energy dispersive X-ray(EDS), X-ray diffraction(XRD), UV–vis diffuse reflectance spectroscopy(DRS) and vibrating sample magnetometer(VSM) techniques. The photocatalytic activity of Fe_3O_4@SiO_2@TiO_2@Ho was investigated by degradation of methyl orange(MO) as cationic dye and rhodamine B(Rh B) as anionic dye in aqueous solution under UV/vis irradiation. The results indicate that about 92.1% of Rh B and78.4% of MO were degraded after 120 and 150 min, respectively. These degradation results show that Fe_3O_4@SiO_2@TiO_2@Ho nanoparticles are better photocatalyst than Fe3O4@Si O2@TiO 2@Ho for degradation of MO and Rh B. As well as, the catalyst shows high recovery and stability even after several separation cycles. | Sobhan Mortazavi-Derazkola Masoud Salavati-Niasari Omid Amiri Ali Abbasi | 2017 | Journal of Energy Chemistry2017，26，1： | 8 |
| 19 | Efficient degradation of chlorobenzene in a non-thermal plasma catalytic reactor supported on CeO_2/HZSM-5 catalysts显示文摘Chlorobenzene removal was investigated in a non-thermal plasma reactor using CeO_2/HZSM-5catalysts.The performance of catalysts was evaluated in terms of removal and energy efficiency.The decomposition products of chlorobenzene were analyzed.The results show that CeO_2/HZSM-5 exhibited a good catalytic activity,which resulted in enhancements of chlorobenzene removal,energy efficiency,and the formation of lower amounts of by-products.With regards to CO_2 selectivity,the presence of catalysts favors the oxidation of by-products,leading to a higher CO_2 selectivity.With respect to ozone,which is considered as an unavoidable by-product in air plasma reactors,a noticeable decrease in its concentration was observed in the presence of catalysts.Furthermore,the stability of the catalyst was investigated by analyzing the evolution of conversion in time.The experiment results indicated that CeO_2/HZSM-5 catalysts have excellent stability:chlorobenzene conversion only decreased from 78%to 60%after 75 hr,which means that the CeO_2/HZSM-5 suffered a slight deactivation.Some organic compounds and chlorinated intermediates were adsorbed or deposited on the catalysts surface as shown by the results of Fourier Transform Infrared(FT-IR) spectroscopy,scanning electron microscope(SEM) and energy dispersive X-ray spectroscopy(EDS) analyses of the catalyst before and after the reaction,revealing the cause of catalyst deactivation. | Liying Jiang Guofeng Nie Runye Zhu Jiade Wang Jianmeng Chen Yubo Mao Zhuowei Cheng Willam A.Anderson | 2017 | Journal of Environmental Sciences2017，29，5： | 8 |
