g-C₃N₄ Nanosheet Supported CuO Nanocomposites for the Electrochemical Carbon Dioxide Reduction Reaction.

ABSTRACT: We have prepared CuO-derived electrocatalysts on a graphitic carbon nitride (g-C₃N₄) nanosheet support for the electrochemical carbon dioxide reduction reaction (CO₂RR). Highly monodisperse CuO nanocrystals made by a modified colloidal synthesis method serve as the precatalysts. We use a two-stage thermal treatment to address the active site blockage issues caused by the residual C18 capping agents. The results show that the thermal treatment effectively removed the capping agents and increased the electrochemical surface area. During the process, the residual oleylamine molecules incompletely reduced CuO to a Cu₂O/Cu mixed phase in the first stage of thermal treatment, and the following treatment in forming gas at 200 °C completed the red
