Ni-N Doped Porous Carbon for Electrocatalytic Reduction of CO₂ into CO Driven by Solar Energy

School of Chemistry, Beihang University, Beijing 100083, R. P. China

Received Date: 12 December 2019

The electroreduction of CO₂ into value-added chemicals and fuels has garnered a broad interest by using renewable clean energy, due to both alleviating global warming and completing the carbon cycle. Herein, a high-performance Ni-N doped porous carbon catalyst was prepared through pyrolysis of hydrogen containing peptone, NiCl₂, and NaCl made by a freeze dry method. The Ni-N-doped porous carbon catalyst displayed an excellent performance of CO₂ electroreduction with a Faraday efficiency of 92.0% at -0.66 V (vs. RHE), 550 mV overpotential,and 2.5 mA·cm^-2 current density. The catalytic performances were attributed to the Ni-N active sites and porous structures. In addition, CO₂ electroreduction to CO was performed continuously by using solar energy, which may provide a valuable reference for carbon cycle in future.
