The generation of green hydrogen(H_2) energy is of great significance to solve worldwide energy and environmental issues. Reduced Ti based photocatalyst has recently attracted intensive attention due to its excellent photocatalytic activity, while the synthesis of reduced Ti based photocatalysts with high stability is still a great challenge. Here, we report a facile method for synthesis of reduced Ti metal organic frameworks(small amounts of Pt incorporated) encapsulated BP(BP/R-Ti-MOFs/Pt) hybrid nanomaterial with enhanced photocatalytic activity. The strong interaction between Ti and P reduces the valence state of the binding Ti^(4+)on the BP surface, forming abundant reduced Ti^(4+)within R-Ti-MOFs/BP. Such reduced Ti^(4+)render R-Ti-MOFs/BP efficient charge transfer and excellent light absorption capability, thus promote the photocatalytic H_2 production efficiency. Furthermore, the Ti-P interaction stabilizes both reduced Ti^(4+)and BP during the photocatalytic reaction, which greatly enhanced the stability of the obtained BP/R-TiMOFs/Pt photocatalyst.

A hint from phosphine complex: The π back-bonding in cobalt-phosphorene composite enables enhanced electrocatalytic performance

引用

Progress in Natural Science:Materials International 2023年第1期33卷 100-107页

作者： Xingyun Li liangping xiao Hao Wang Jingting Song Qingchi Xu Meidan Ye Jun Xu Shenzhen Research Institute of Xiamen University Department of Physics Research Institute for Biomimetics and Soft Matter Fujian Provincial Key Laboratory for Soft Functional Materials Xiamen University Jiujiang Research Institute of Xiamen University Department of Chemistry National University of Singapore

Regulating the electronic structure of the metal electrocatalyst is fundamental for its performance optimizing. The electronic states of the active metal centers are highly dependent on their coordination environment, especially when bonding is formed. The π back-bonding can induce great electron density redistribution around metals, yet it is barely applied in electrocatalyst design. Herein we electrodeposited metallic cobalt on black phosphorus(BP)nanosheets, forming BP-Co with a unique π back-bonding on the interfaces. The BP-Co exhibited high electrocatalytic activity and stability for hydrogen evolution reaction in alkaline electrolyte. The electrochemical and spectroscopic characterizations demonstrated that the BP acted as σ donor and π acceptor to coordinate with electron-rich metallic Co, similar to the phosphine complex. The directional σ bond strengthen the relationship between BP and Co, while the non-directional π bond accelerated the in-plane electron transfer. The π back donation also decreased the oxophilicity of Co to make BP-Co resist the poison from oxygen species. This study can intrigue new thinking prospective for the electrocatalyst design.

马克思主义关于社会存在与社会意识关系的原理为马克思主义环境论奠定了唯物论基础,认为环境对人的影响将随着社会发展呈现不同特征和不同阶段,并对唯心主义环境论和机械唯物主义环境论进行了批判。全面从严治党是新时代的重要主题之一,按照马克思主义环境论的观点,全面从严治党与环境相互影响,全面从严治党影响着环境,环境也影响着全面从严治党。全面从严治党环境具有阶级性、方向性、全面性、严肃性、可控性和多样性等特点,并可以按照形式、性质、内容、层次分为不同的环境类别。其中按层次分的国家环境、社会环境、家庭环境、个人环境对全面从严治党有着重要影响。为此,要综合系统地、有选择性地、积极主动地优化和开发全面从严治党的教育环境、政治环境和舆论环境。
