多孔自支撑电极电催化还原二氧化碳
Self-supported porous electrodes for efficient electrocatalytic CO2 reduction
摘要
Abstract
Electrochemical reduction of CO2 to value-added fuels by renewable clean energy is an effective way to achieve energy storage,carbon emission reduction and carbon neutrality.However,due to the low solubility of reactant CO2 in aqueous electrolytes,limitations in mass transfer processes seriously hinder the electrocatalytic reaction to meet the requirements for achieving industrial operation.To resolve this problem,the self-supported porous electrodes attract much attention.This paper first introduced the research progress of self-supported porous electrodes and illustrated the latest results of CO2 electroreduction from new self-supported porous hollow fiber gas penetrating electrodes in our research group.Considering the continuous and ample CO2 feeding realized nearby active sites on this electrode structure,a new technology model perspective of enhanced interface reaction and oriented mass transfer by gas penetration electrodes was put forward,which can become a new technology route to prepare self-supported porous electrodes and would exert significant implications for the industrialization of electrocatalytic CO2 reduction.关键词
