Recent advances in nickel‐based catalysts in eCO₂RR for carbon neutrality

Abstract

Abstract The excessive use of nonrenewable energy has brought about serious greenhouse effect. Converting CO 2 into high‐value‐added chemicals is undoubtedly the best choice to solve energy problems. Due to the excellent cost‐effectiveness and dramatic catalytic performance, nickel‐based catalysts have been considered as the most promising candidates for the electrocatalytic CO 2 reduction reaction (eCO 2 RR). In this work, the electrocatalytic reduction mechanism of CO 2 over Ni‐based materials is reviewed. The strategies to improve the eCO 2 RR performance are emphasized. Moreover, the research on Ni‐based materials for syngas generation is briefly summarized. Finally, the prospects of nickel‐based materials in the eCO 2 RR are provided with the hope of improving transition‐metal‐based electrocatalysts for eCO 2 RR in the future.
