Utilizing the special structure of 1,3,5-triynylbenzene, Cu single atom catalysts with a Cu−C₂ coordination structure were prepared for the first time and showed excellent performance in the electrochemical reduction of CO₂ (e-CO₂RR) process. Comprehensive experiments and calculations confirmed that the Cu−C₂ structure not only endowed the Cu single atoms center with more positive charge, but also promoted the formation of H⋅, which improved the electrocatalytic performance of CO₂RR to CH₄.

低配位 Cu−C2 单原子电催化剂的构建促进高效电化学 CO2 还原为甲烷

利用1,3,5-三炔基苯的特殊结构，首次制备出具有Cu−C _{2配位结构的Cu单原子催化剂，并在电化学还原CO}₂ (e-CO ₂ RR)过程中表现出优异的性能。综合实验和计算证实，Cu−C ₂结构不仅赋予Cu单原子中心更多的正电荷，而且促进了H⋅的形成，提高了CO ₂ RR对CH ₄的电催化性能。
