摘要
铜基催化剂能高效地将CO_(2)深度电化学还原(CORR)为多碳烃类化合物,其催化性能与催化剂的结构有关。我们以大学无机化学实验“过氧化钙的制备及含量测定”为基础,设计了集合成、形貌结构表征和CORR的性能应用研究为一体的综合研究型实验。结果表明铜氧化物催化剂的形貌结构对CORR产物的选择性具有显著的差异。本综合研究型实验内容丰富,有助于提升学生化学专业核心素养,符合新时代化学学科的发展要求。
Copper-based catalysts are a kind of metal catalyst that can efficiently and deeply reduce CO_(2)electrochemical reduction(CORR)to multi-carbon hydrocarbons.The selectivity and Faraday efficiency of CO_(2)electrochemical reduction largely depended on the structure of the catalyst.We improved the task-typical synthesis experiment of“preparation and content determination of calcium peroxide”from an inorganic chemistry experiment to a comprehensive research experiment,which combined the study of structure and morphology of Cu based catalysts for the application of CORR.This comprehensive research experiment showed that the selectivity of different copper oxide catalysts for CORR was significantly different.At the same time,the improved experiment is helpful to enhance the cultivation of students’core quality of chemistry,and more in line with the development of chemistry in the new era.
