氮掺杂生物质炭耦合氧化铜材料用于电催化还原CO2
Nitrogen-doped Biomass Carbon Coupled with Copper Oxide Materials for Electrocatalytic Reduction of CO2
摘要
Abstract
[Purposes]Electrocatalytic technology for converting CO2 into high-value-added fuels and chemicals has promising applications.However,developing electrocatalysts with superior perfor-mance still faces significant challenges.[Methods]In this study,wheat bran was used as the precursor of biomass carbon and the pyrolysis method was used to prepare nitrogen-doped biomass carbon mate-rials(NC).By further coupling with CuO via a hydrothermal method,a series of CuO@NC composite materials were costructed.The crystalline phase,microscopic morphology,structure,and elemental valence states were analyzed by multiple characterization techniques.The electrocatalytic performance was investigated towards the electrocatalytic reduction of CO2.[Findings]Results indicate that the composite catalyst synthesized at 160℃(CuO@NC-160)exhibits high selectivity towards ethylene,with a maximum faradaic efficiency of 26.85%at-1.18 V vs.RHE.This study presents a feasible pathway for fabricating low-cost and efficient CuO-based electrocatalysts.关键词
