| 1 | Single-atom site catalysts for environmental catalysis显示文摘In recent decades,the environmental protection and long-term sustainability have become the focus of attention due to the increasing pollution generated by the intense industrialization.To overcome these issues,environmental catalysis has increasingly been used to solve the negative impact of pollutants emission on the global environment and human health.Supported platinum-metal-group(PGM)materials are commonly utilized as the state-of-the-art catalysts to eliminate gaseous pollutants but large quantities of PGMs are required.By comparison,single-atom site catalysts(SACs)have attracted much attention in catalysis owing to their 100%atom efficiency and unique catalytic performances towards various reactions.Over the past decade,we have witnessed burgeoning interests of SACs in heterogeneous catalysis.However,to the best of our knowledge,the systematic summary and analysis of SACs in catalytic elimination of environmental pollutants has not yet been reported.In this paper,we summarize and discuss the environmental catalysis applications of SACs.Particular focus was paid to automotive and stationary emission control,including model reaction(CO oxidation,NO reduction and hydrocarbon oxidation),overall reaction(three-way catalytic and diesel oxidation reaction),elimination of volatile organic compounds(formaldehyde,benzene,and toluene),and removal/decomposition of other pollutants(Hg0 and SO3).Perspectives related to further challenges,directions and design strategies of single-atom site catalysts in environmental catalysis were also provided. | Ningqiang Zhang Chenliang Ye Han Yan Lingcong Li Hong He Dingsheng Wang Yadong Li | 2020 | Nano Research2020，13，12： | 38 |

| 3 | Multi-node CdS hetero-nanowires grown with defect-rich oxygen-doped MoS2 ultrathin nanosheets for efficient visible-light photocatalytic H2 evolution显示文摘Developing low-cost and high-efficiency photocatalysts for hydrogen production from solar water splitting is intriguing but challenging. In this study, unique one-dimensional (1D) multi-node MoS2/CdS hetero-nanowires (NWs) for efficient visible-light photocatalytic H2 evolution are synthesized via a facile hydrothermal method. Flower-like sheaths are assembled from numerous defect-rich O-incorporated {0001} MoS2 ultrathin nanosheets (NSs), and {112̅0}-facet surrounded CdS NW stems are grown preferentially along the c-axis. Interestingly, the defects in the MoS2 NSs provide additional active S atoms on the exposed edge sites, and the incorporation of O reduces the energy barrier for H2 evolution and increases the electric conductivity of the MoS2 NSs. Moreover, the recombination of photoinduced charge carriers is significantly inhibited by the heterojunction formed between the MoS2 NSs and CdS NWs. Therefore, in the absence of noble metals as co-catalysts, the 1D MoS2 NS/CdS NW hybrids exhibit an excellent H2-generation rate of 10.85 mmol·g-1·h-1 and a quantum yield of 22.0% at λ = 475 nm, which is far better than those of Pt/CdS NWs, pure MoS2 NSs, and CdS NWs as well as their physical mixtures. Our results contribute to the rational construction of highly reactive nanostructures for various catalytic applications. | Haifeng Lin Yanyan Li Haoyi Li Xun Wang | 2017 | Nano Research2017，10，4： | 5 |
| 4 | Pd@Au核壳结构纳米颗粒在CO和O_2中动态变化的原位电镜研究显示文摘由于其广泛的催化适用性及优异的催化性能,PdAu双金属纳米催化剂一直以来都备受重视。本文以Pd@Au球形纳米颗粒为研究对象,使用气体样品杆系统在透射电子显微镜中原位观察了300℃退火过程中,纳米颗粒在一个大气压的CO或O_2环境下的动态变化。实验发现,Pd@Au球形纳米颗粒在CO中发生剧烈的形貌变化,暴露出大量的{111}面。CO在PdAu合金表面的选择性吸附可能是发生形貌变化的主要原因。而在O_2气氛中,Pd在300℃退火条件下向颗粒表面快速析出并形成PdO团簇。Pd@Au纳米颗粒在300℃下的快速合金化以及O_2对Pd的诱导作用是形成该变化的原因。依靠着Au壳层的保护,Pd@Au纳米颗粒的核壳结构在300℃以下可以保持稳定。 | 吴哲敏 楼锦泽 欧阳 王勇 张泽 | 2019 | 电子显微学报2019，38，2： | 5 |

| 11 | Heterogeneous catalysis for green chemistry based on nanocrystals显示文摘Modern society has an ever-increasing demand for environmentally friendly catalytic processes. Catalysis research is working towards a solution through the development of efective heterogeneous catalysts for environment-related applications. Nanotechnologies have provided efective strategies for the preparation of nanocrystals(NCs) with well-deined sizes, shapes and compositions. Precise control of these NCs provides an important foundation for the studies of structure-performance relationships in catalysis, which is critical to the design of NCs with optimized catalytic performances for practical applications. We focus on recent advances in the development of botom-up strategies to control NCs structures for some key catalytic applications, including CO oxidation, selective oxidation of alcohols, semihydrogenation of alkynes, and selective hydrogenation of unsaturated aldehydes and nitrobenzene. hese key applications have been a popular research focus because of their signiicance in green chemistry. Herein we also discuss the scientiic understandings of the active species and active structures of these systems to gain an insight for rational design of eicient catalytic systems for these catalytic reactions. | Yuxi Liu Guofeng Zhao Dingsheng Wang Yadong Li | 2015 | National Science Review2015，2，2： | 2 |
| 12 | Catalytically active interfaces in titania nanorod-supported copper catalysts for CO oxidation显示文摘One-dimensional titanium dioxide nanorod(TNR)-supported Cu catalysts(2.5 wt.%-12.5 wt.%)were synthesized using deposition-precipitation.X-ray photoelectron spectroscopy,temperature programmed reduction and CO chemisorption measurements showed that Cu doping over TNR offered metal-support interactions and interfacial active sites that had a profound impact on the catalytic performance.The role of the Cu-TNR interface was investigated by comparing the catalytic activity of Cu-TNR catalysts with that of pure CuO nanoparticles in CO oxidation.The presence of highly dispersed copper species,a high number of interfacial active sites,CO adsorption capacity and surface/lattice oxygen were found to be responsible for the excellent activity of 7.5CU-TNR(ie,Cu loading of 7.5 wt.%on TNR).Moreover,the Cu-TNR catalysts followed the Langmuir-Hinshelwood reaction mechanism with 7.5CU-TNR,exhibiting an apparent activation energy of 44.7 kJ/mol.The TNR-supported Cu catalyst gave the highest interfacial catalytic activity in medium-temperature CO oxidation(120-240℃)compared to other commonly used supports,including titanium dioxide nanoparticles(TiO2-P25),silica(SiO2)and alumina(Al20g)in which copper species were nonhomogeneously dispersed.This study confirms that medium-temperature CO oxidation is highly sensitive to the morphology and structure of the supporting material. | Wasim U.Khan Season S.Chen Daniel C.W.Tsang Wey Yang Teoh Xijun Hu Frank L.Y.Lam Alex C.K.Yip | 2020 | Nano Research2020，13，2： | 2 |
| 13 | Interaction of citrate with Pt(100) surface investigated by cyclic voltammetry towards understanding the structure-tuning effect in nanomaterials synthesis显示文摘This study aims to understand the effects of functional agents such as capping agents, stabilizers, surfactants and additives in shape-controlled synthesis of nanomaterials. The well-defined Pt(100) single crystal surface was used as a model to investigate its interaction with citrate, a capping agent that is often used in shape-controlled synthesis of nanomaterials. It demonstrated that, through a systematic study of electrochemical cyclic voltammetry, the presence of citrate in solution could increase the current peak density of hydrogen adsorption at high potential (j p,L ), while decrease proportionally the current peak density of hydrogen adsorption at low potential (j p,S ). Furthermore, the increase of citrate concentration shifted negatively the peak potentials (E p,L and E p,S ) of both j p,L and j p,S . The results indicated that the interaction of citrate with Pt(100) surface could induce increasing the (100) surface domains of two-dimensional long range order (2D-(100)), and decreasing the (100) surface domains of one-dimensional short range order (1D-(100)). It also revealed that the interaction of citrate with Pt(100) surface could stabilize the 2D-(100) structure. The findings gained in this study implied that the citrate may lead to form stable 2D-(100) domains on Pt nanoparticles upon the shape-controlled synthesis of Pt nanomaterials. | CHEN DeHao YE JinYu XU ChangDeng LI Xin LI JunTao ZHEN ChunHua TIAN Na ZHOU ZhiYou SUN ShiGang | 2012 | Science China Chemistry2012，55，11： | 1 |
| 14 | Fine-tuning of Pd-Rh core-shell catalysts by interstitial hydrogen doping for enhanced methanol oxidation显示文摘Metal catalysts play an important role in the catalytic electrochemical processes and optimization of their performance is usually achieved through alloying with other metal atoms.Doping with interstitial hydrogen atoms is a special but effective way to regulate the electronic structure of host catalysts.Herein we demonstrate the intermixing of Pd and Rh atoms during the hydrogen-doping process of Pd@Rh core-shell nanocubes,forming an alloyed surface in Pd@Rh-H.The catalysts show enhanced performance in electrocatalytic methanol oxidation,as compared to commercial Pt/C and are even better than PdH@Rh core-shell nanocubes.The small structural differences between the two hydride catalysts are revealed by X-ray electron spectroscopy and pair distribution function analysis of electron diffraction.The theoretical calculation results show that Rh in Pd@Rh-H contains more negative charges than Rh in PdH@Rh,indicating more effective charge transfer in Pd@Rh-H.The d-band center(£d)of the Rh site in Pd@Rh-H shifts up,and the synergy between Rh and Pd optimizes the binding energy of CO and OH,inducing preferential catalytic activity.Our work provides guidance for the synthesis of high-performance catalysts by doping with interstitial atoms,which may provide a new strategy to fine-tune the electronic structure of other bimetallic nanoparticles. | Xiaoyun Guo Zheng Hu Jianxin Lv Hui Li Qinghua Zhang Lin Gu Wei Zhou Jiangwei Zhang Shi Hu | 2022 | Nano Research2022，15，2： | 1 |
