摘要

Abstract

Nickel nanoparticles(Ni NPs)encapsulated in carbon shells have shown promise in the electrochemical reduction of CO2 to CO.The electron-ic regulation of the interface between Ni NPs and carbon shells plays a cru-cial role in reducing the energy barrier of the CO reaction path.We report the formation of a catalyst with hierarchical porosity(Ni NPs@NC)using a high-surface-area 3D Ni-MOF as the precursor.By correlating the pyrolysis temperature with structural changes and catalytic efficiency,structure-activ-ity relationships were established.Because of the confined encapsulation of the Ni NPs by the N-doped carbon layer,the frame-work does not collapse during pyrolysis but also produces a high-density of exposed Ni-N active sites and better mass transport paths.Notably,the Ni NPs@NC-800 sample had an outstanding electrocatalytic performance for CO2 reduction,achieving a maximum Faradaic Efficiency(FE)of 93%at-0.8 V vs RHE,and maintaining over 90%efficiency even after 48 h of continu-ous operation.Raman spectroscopy showed that the interface between the Ni NPs and the carbon shell play a critical role in sta-bilizing the critical COOH intermediate,promoting CO desorption and inhibiting the competing hydrogen evolution reaction.This work may provide insight for producing catalysts for efficient electrochemical CO2 reduction over a wide potential range.
