CuO纳米线电催化甘油氧化耦合CO2还原实现双极产甲酸盐OA

CuO Nanowires Arrays for Glycerol Oxidation Coupled with CO2 Electroreduction Towards Bipolar Formate Production

中文摘要英文摘要

为开发高效、低成本甘油电氧化反应(glycerol electro-oxidation reaction,GOR)催化剂,制备了一种泡沫铜(copper foam,CF)负载的氧化铜纳米线阵列(CuO/CF)阳极材料.以该材料为阳极,与催化 CO2 还原反应(CO₂reduction reaction,CO2RR)的In2O3/CP阴极耦合,构建CO2RR||GOR双电极耦合电解体系.结果表明,在氧化电位为1.5 V下,CuO/CF催化GOR生成甲酸盐,法拉第效率(ηfe)可达98.0%,该材料表现出优异的催化活性与反应选择性;在电解池电压为3.0 V下,该电解体系可实现阴阳两极同步联产甲酸盐,阴极CO2RR、阳极GOR的ηfe分别达86.1%、95.2%.该研究不仅为高效GOR催化剂的研发提供了全新思路,也为阴阳两极同步联产甲酸盐的高值化路径研究提供了重要参考.

To develop an efficient and low-cost electrocatalyst for the glycerol oxidation reaction(GOR),a cop-per foam-supported CuO nanowire array(CuO/CF)anode was prepared.The CuO/CF anode was then cou-pled with an In2O3/CP cathode for the CO2 reduction reaction(CO2RR)to construct a CO2RR||GOR dual-electrode coupled electrolysis system.At an oxidation potential of 1.5 V,the system exhibited a Faradaic effi-ciency(ηfe)of up to 98.0%for formate production from GOR,demonstrating outstanding reaction selectivity and catalytic activity.At a cell voltage of 3.0 V,simultaneous formate production at both the cathode and anode was achieved,with ηfe of 86.1%for cathodic CO2RR and 95.2%for anodic GOR,respectively.This study provides a new strategy for developing efficient GOR electrocatalysts and offers important guidance for the value-added routes for the simultaneous production of formate at both electrodes.
