Electrochemical reduction of carbon dioxide (CO2RR) is a promising strategy for mitigating global warming and producing value-added products simultaneously. Molecular catalysts, such as cobalt phthalocyanine (CoPc), are known to be effective in converting (CO2) monoxide (CO). However, it still challenging improve the reaction rate selectivity this conversion. Herein, we report simple coadsorption promote CoPc-catalyzed CO2RR CO by coadsorbing melamine molecules together with CoPc onto surface nanotubes (CNTs). The led an increase output current density 2.6-fold at overpotential -1.23 V vs Ag|AgCl. Moreover, Faraday efficiency (FE) toward increased 92% H-type cell, contrast FE 85% absence coadsorption. further improved 99% flow cell system. It was revealed that could modulate adsorption *CO intermediates decrease energy barrier CO2 CO. More importantly, only solution-based process employed whole procedure no organic synthesis involved, making our method highly simple, convenient, environment friendly. This work paves way modulating activity molecular catalysts CO2RR.
