| 1 | Exploring the Roles of Single Atom in Hydrogen Peroxide Photosynthesis显示文摘This comprehensive review provides a deep exploration of the unique roles of single atom catalysts(SACs)in photocatalytic hydrogen peroxide(H_(2)O_(2))production.SACs offer multiple benefits over traditional catalysts such as improved efficiency,selectivity,and flexibility due to their distinct electronic structure and unique properties.The review discusses the critical elements in the design of SACs,including the choice of metal atom,host material,and coordination environment,and how these elements impact the catalytic activity.The role of single atoms in photocatalytic H_(2)O_(2)production is also analysed,focusing on enhancing light absorption and charge generation,improving the migration and separation of charge carriers,and lowering the energy barrier of adsorption and activation of reactants.Despite these advantages,several challenges,including H_(2)O_(2)decomposition,stability of SACs,unclear mechanism,and low selectivity,need to be overcome.Looking towards the future,the review suggests promising research directions such as direct utilization of H_(2)O_(2),high-throughput synthesis and screening,the creation of dual active sites,and employing density functional theory for investigating the mechanisms of SACs in H_(2)O_(2)photosynthesis.This review provides valuable insights into the potential of single atom catalysts for advancing the field of photocatalytic H_(2)O_(2)production. | Kelin He Zimo Huang Chao Chen Chuntian Qiu Yu Lin Zhong Qitao Zhang | 2024 | Nano-Micro Letters2024，16，2： | 0 |
| 2 | 非贵金属氮碳材料在氧还原方向的研究进展显示文摘氧还原反应作为一种重要的电化学过程,在燃料电池、电解水和电池等能源转换器件中扮演关键的角色。随着对能源转换技术的不断探索和研究,氧还原反应已经引起了关注。目前,Pt碳催化剂是最有效的氧还原反应催化剂,但其高成本和稀缺性限制了商业化应用。通过以氮碳材料为载体,开发低成本、高效率的非贵金属催化剂替代Pt碳催化剂,成为氧还原反应研究的热点。聚焦制备低成本、高性能的非贵金属催化剂及在氧还原中的应用。 | 曹智雅 邓方健 李雨情 陈蕊 | 2023 | 化工科技2023，31，4： | 0 |
| 3 | 氢燃料电池阴极氧还原反应电催化剂研究进展显示文摘氢燃料电池是一种将化学能直接转换为电能的能量转换装置,具有转换效率高、噪声低、无污染、原料多样且用途广泛等优点,但其阴极氧还原反应(oxygen reduction reaction,ORR)动力学缓慢,极大地限制了其大规模应用与发展.因此,研发高效、耐用兼具经济性的ORR电催化剂是当前研究热点之一.在众多科研工作者的努力下,关于ORR电催化剂的研究工作已取得了许多重要突破性进展.本综述系统介绍了ORR反应机制和目前3种主流类别的ORR电催化剂(贵金属、非贵金属、碳基)的研究进展,着重分析了不同催化剂体系的性能与优缺点,并探讨了高性能ORR电催化剂的合成策略及其未来的发展方向. | 李雅银 袁萌伟 王迪 石柯凡 孙根班 | 2021 | 北京师范大学学报(自然科学版)2021，57，5： | 0 |
| 4 | Ultra‐low single‐atom Pt on g‐C_(3)N_(4)for electrochemical hydrogen peroxide production显示文摘Platinum-based materials show excellent electrocatalytic performance and have good potential for use in fuel cells.However,the high cost and scarce reserves have restricted their wide application.Therefore,it is a challenging task to reduce the amount of Pt as well as ensure good catalytic performance.Herein,anchoring of Pt single atoms(0.21 wt‰)with ultra-low content on g-C_(3)N_(4)nanosheets(Pt_(0.21)/CN)has been successfully achieved.The obtained Pt_(0.21)/CN catalyst shows excellent two-electron oxygen reduction(2e-ORR)capability for hydrogen peroxide(H_(2)O_(2)).Compared with CN,its H_(2)O_(2)selectivity increased from 80%to 98%in 0.1M KOH,surpassing those in most of the reported studies.Besides,the H_(2)O_(2)production rate of Pt_(0.21)/CN is 767 mmol gcat^(-1)h-1,which is 11.1 times that of CN.This work may pave the way toward the development of an effective method for the design of noblemetal electrocatalysts with low metal loading and high catalytic activity. | Hongcen Yang Niandi Lu Juntao Zhang Rui Wang Shuhao Tian Mengjun Wang Zhixia Wang Kun Tao Fei Ma Shanglong Peng | 2023 | Carbon Energy2023，5，9： | 0 |
