Recent Advances in Bismuth-Based CO2 Reduction Electrocatalysts

 二氧化碳（CO2）作为一种经济、安全、可再生的碳资源化合物，其高效回收利用一直是全社会关注的焦点. 利用电化学方法，将CO2还原转化生成一系列高附加值的化学品或燃料，对于缓解能源与环境双重压力具有重要的现实意义. 本论文介绍了电化学CO2还原反应的基本原理与过程，综述了近年来铋基催化材料的发展现状，重点对这类催化材料的制备合成、结构调控、催化反应机理研究等方面进行了总结，最后对其未来发展方向进行了探讨与展望.Carbon dioxide (CO2) is an economical, secure and sustainable carbon resource around us. Its effective capture and recycling have been the focus of our entire society. Using the electrochemical method, CO2 can be reduced to different value-added chemicals or fuels. This approach not only would mitigate CO2 accumulation in the atmosphere, but also would help alleviate our dependence on fossil fuel. In this article, the basic principle and process of electrochemical CO2 reduction are first introduced. The recent development in bismuth-based catalysts for electrocatalytic CO2 reduction is reviewed with an emphasis on their preparation, structure characterization, and possible reaction mechanism. Finally, a perspective on future development is briefly discussed.  国家自然科学基金项目(No. 51522208)资助作者联系地址：（苏州大学功能纳米与软物质研究院，江苏 苏州 215000）Author's Address: Institute of Functional Nano & Soft Materials FUNSOM, Jiangsu Key Laboratory for Carbon-Based Functional Materials and Devices, Soochow University, Suzhou 215123, Jiangsu, China通讯作者E-mail：hanna@suda.edu.cn; yanguang@suda.edu.c
