1A review on photo-thermal catalytic conversion of carbon dioxide显示文摘The conversion of carbon dioxide into value-added products is of great industrial and environmental interest. However, as carbon dioxide is relatively stable, the input energy required for this conversion is a significant limiting factor in the system's performance. By utilising energy from the sun, through a range of key routes, this limitation can be overcome. In this review, we present a comprehensive and critical overview of the potential routes to harvest the sun's energy, primarily through solar-thermal technologies and plasmonic resonance effects. Focusing on the localised heating approach, this review shortlists and compares viable catalysts for the photo-thermal catalytic conversion of carbon dioxide.Further, the pathways and potential products of different carbon dioxide conversion routes are outlined with the reverse water gas shift,methanation, and methanol synthesis being of key interest. Finally, the challenges in implementing such systems and the outlook to the future are detailed.Ee Teng Kho Tze Hao Tan Emma Lovell Roong Jien Wong Jason Scott Rose Amal 2017Green Energy & Environment2017,2,3:7
2Harnessing the Beneficial Attributes of Ceria and Titania in a Mixed-Oxide Support for Nickel-Catalyzed Photothermal CO_2 Methanation显示文摘太阳能驱动二氧化碳(CO_2)转化为燃料是解决CO_2减排和快速增长的世界能源需求的理想方案。本文利用光照辐射镍基负载催化剂床层引发加热效应以促进CO_2的转化,研究了不同组成的氧化铈-氧化钛复合氧化物载体及其对光热CO_2转化的影响。提高光热CO_2甲烷化活性的两个至关重要的因素分别是:(1)优化的镍颗粒负载对于高活性催化面积及用于加热催化床层的更高的光吸收能力是必需的;(2)载体上的缺陷位对于促进CO_2吸附及随后的活化是必需的。载体中的钛对维持掺杂氧化钛的氧化铈上的氧空位缺陷起着关键作用。当氧化铈和氧化钛混合比例理想时,再结合高光照吸收以及稳定的还原状态,有利于CO_2吸附及随后高效光热CO_2甲烷化反应的发生。Ee Teng Kho Salina Jantarang Zhaoke Zheng Jason Scott Rose Amal 2017Engineering2017,3,3:2
3Recent advances in flexible batteries:From materials to applications显示文摘Along with the rapid development of flexible and wearable electronic devices,there have been a strong demand for flexible power sources,which has in turn triggered considerable efforts on the research and development of flexible batteries.An ideal flexible battery would have not only just high electrochemical performance but also excellent mechanical deformabilities.Therefore,battery constituent components,chemistry systems,device configurations,and practical applications are all pivotal aspects that should be thoroughly considered.Herein,we systematically and comprehensively review the fundamentals and recent progresses of flexible batteries in terms of these important aspects.Specifically,we first discuss the requirements for constituent components,including the current collector,electrolyte,and separator,in flexible batteries.We then elucidate battery chemistry systems that have been studied for various flexible batteries,including lithium-ion batteries,non-lithium-ion batteries,and high-energy metal batteries.This is followed by discussions on the device configurations for flexible batteries,including onedimensional fiber-shaped,two-dimensional film-shaped,and three-dimensional structural batteries.Finally,we summarize recent efforts in exploring practical applications for flexible batteries.Current challenges and future opportunities for the research and development of flexible batteries are also discussed.Fuwei Xiang Fang Cheng Yongjiang Sun Xiaoping Yang Wen Lu Rose Amal Liming Dai 2023Nano Research2023,16,4:1

5CuInS_2-In_2O_3-TiO_2纳米管阵列薄膜双电介质体系在光电化学产氢中的应用(英文)显示文摘光电化学电池产氢过程中利用Na_2S/Na_2SO_3混合物作为电解质溶液稳定硫化物阳极通常会牺牲电流产氢效率(η_(current)).本文采用Na_2S/Na_2SO_3和p H中性的Na_2SO_4分别作为光解水电池的阳极和阴极电解液可有效抑制CuInS_2-In_2O_3-TiO_2(CIS-In_2O_3-TNT)纳米管杂化结构的光腐蚀,同时提高η_(current).通过脉冲辅助电沉积法可将n型CIS和In_2O_3纳米粒子沉积在TNT阵列表面,在保留TNT原有中空结构的前提下将纳米粒子均匀沉积在纳米管上对于在杂化结构中获得高效电荷聚集和分离非常必要.与Na_2S/Na_2SO_3单电解液电池相比双电解液的引入不仅提高了CIS-In_2O_3-TNT阳极的光稳定性,而且η_(current)接近于1并远高于单电解液电池(20%).Charlene Ng Jung-Ho Yun Hui Ling Tan Hao Wu Rose Amal Yun Hau Ng 2018Science China Materials2018,61,6:1

9Emerging material engineering strategies for amplifying photothermal heterogeneous CO_(2)catalysis显示文摘Closing the carbon loop,through CO_(2)capture and utilization,is a promising route to mitigate climate change.Solar energy is a sustainable energy source which can be exploited to drive catalytic reactions for utilizing CO_(2),including converting the CO_(2)into useful products.Solar energy can be harnessed through a range of different pathways to valorize CO_(2).Whilst using solar energy to drive CO_(2)reduction has vast potential to promote catalytic CO_(2)conversions,the progress is limited due to the lack of understanding of property-performance relations as well as feasible material engineering approaches.Herein,we outline the various driving forces involved in photothermal CO_(2)catalysis.The heat from solar energy can be utilized to induce CO_(2)catalytic reduction reactions via the photothermal effect.Further,solar energy can act to modify reaction pathways through light-matter interactions.Light-induced chemical functions have demonstrated the ability to regulate intermediary reaction steps,and thus control the reaction selectivity.Photothermal catalyst structures and specific catalyst design strategies are discussed in this context.This review provides a comprehensive understanding of the heat-light synergy and guidance for rational photothermal catalyst design for CO_(2)utilization.Bingqiao Xie Emma Lovell Tze Hao Tan Salina Jantarang Mengying Yu Jason Scott Rose Amal 2021Journal of Energy Chemistry2021,30,8:1

11An integrated nanocarbon–cellulose membrane for solid-state supercapacitors显示文摘In this work, we demonstrate the assembly of oxidised carbon nanohybrids(o CNHs) with a commercial cellulose membrane for solid-state supercapacitors. The o CNHs–cellulose membranes were prepared by filtering a water dispersion of o CNHs through the cellulose membrane. The o CNHs were derived from carbon nanotubes via a modified Hummer's method and contained both closed tubes and unzipped tubes, which indicated a hybrid geometrical structure. The solid-state supercapacitor based on the o CNHs–cellulose membranes showed a high areal capacitance of *75 m F/cm^2 at a low scan rate(5 m V/s)and excellent stability for 1,000 cycles.Huabo Liu Yuheng Tian Rose Amal Da-Wei Wang 2016Science Bulletin2016,61,5:1

17Carbon-supported layered double hydroxide nanodots for efficient oxygen evolution: Active site identification and activity enhancement显示文摘In this study,we developed a novel confinement-synthesis approach to layered double hydroxide nanodots(LDH-NDs)anchored on carbon nanoparticles,which formed a three-dimensional(3D)interconnected network within a porous carbon support derived from pyrolysis of metal-organic frameworks(C-MOF).The resultant LDH-NDs@C-MOF nonprecious metal catalysts were demonstrated to exhibit super-high catalytic performance for oxygen evolution reaction(OER)with excellent operation stability and low overpotential(-230 mV)at an exchange current density of 10 mA·cm^(-2).The observed overpotential for the LDH-NDs@C-MOF is much lower than that of large-sized LDH nanosheets(321 mV),pure carbonized MOF(411 mV),and even commercial RuO_(2)(281 mV).X-ray absorption measurements and density functional theory(DFT)calculations revealed partial charge transfer from Fe^(3+)through an O bridge to Ni^(2+)at the edge of LDH-NDs supported by C-MOF to produce the optimal binding energies for OER intermediates.This,coupled with a large number of exposed active sides and efficient charge and electrolyte/reactant/product transports associated with the porous 3D C-MOF support,significantly boosted the OER performance of the LDH-ND catalyst with respect to its nanosheet counterpart.Apart from the fact that this is the first active side identification for LDH-ND OER catalysts,this work provides a general strategy to enhance activities of nanosheet catalysts by converting them into edge-rich nanodots to be supported by 3D porous carbon architectures.Shenlong Zhao Detao Zhang Shuai Jiang Yanglansen Cui Haijing Li Juncai Dong Zhirun Xie Da-Wei Wang Rose Amal Zhenhai Xia Liming Dai 2021Nano Research2021,14,9:1

20Oxygen-deficient bismuth tungstate and bismuth oxide composite photoanode with improved photostability显示文摘A homogeneous layer of Bi_2O_3-Bi_(14)WO_(24) composite(BWO/Bi_2O_3) thin film was fabricated using a combination of electrodeposition and thermal treatment. The evenly distributed Bi14 WO24 component within the Bi_2O_3 layer was found to be important in stabilising the photoelectrochemical performances of Bi_2O_3 photoanode by promoting the photoelectron transport. The unmodified Bi_2O_3 suffered from severe photocorrosion as proven by X-ray diffraction(XRD) and inductively coupled plasma(ICP) analyses while the composite thin film was active without noticeable activity decay for at least 3 h of illumination. This strategy might be applicable to other photocatalysts with stability issues.Hoi Ying Chung Weijian Chen Xiaoming Wen Judy N.
