Abstract

In this study, novel kinds of CuxO nanocatalysts have been successfully synthesized with different reducing agents (aniline, O-methoxyaniline and 3,5-dimethoxyaniline) by a facile hydrothermal method. The catalytic performances of the as-prepared CuxO nanocatalysts were investigated systematically for the electroreduction of CO2, and compared with the one which has been produced in our previous work using 2,5-dimethoxyaniline as catalyst's synthetic reducing agent. The experiments show that the catalytic activity of CuxO nanocatalysts largely depends on the molecular structure of the reducing agent used for the catalyst's synthesis. Using 3,5-dimethoxyaniline as an effective reducing agent, the obtained CuxO nanocatalyst gives the best catalytic activity in terms of both reduction current density and Faradaic efficiency. A high current dentistry larger than 20 mA cm-2 was observed at -1.25V. The Faradaic efficiency of formate production with a maximum value of 36% was obtained at low potential of -0.7 V vs. SHE.
