化石能源的大规模使用使得大气中CO2的含量不断增加.发展生物质能源等可再生能源,结合CO2的转化利用对降低化石能源的依赖和减少碳排放具有重要的意义.利用可再生电能驱动CO2的电化学还原生成燃料和化学品是CO2转化利用的一个有效途径.本文对CO2电化学转化以及耦合生物质氧化转化新路线的主要研究进展进行了综述.重点介绍了CO2电化学还原的催化剂、反应系统、反应机制等方面的最新进展,以及阳极耦合生物质及其衍生醇类、醛类等氧化转化的新技术.可再生电能驱动的生物质氧化转化与CO2电还原相耦合不仅可以获得高值化学品,而且可以显著减少CO2的净排放.因此,本文可为生物质和CO2转化提供新的思路.
Electrochemical reduction of CO2 coupled with oxidative conversion of biomass
The large-scale use of fossil energy significantly increased CO2 emissions.It is of great importance to decrease the dependence on fossil energy and reduce carbon emission by developing renewable energy such as biomass energy combined with the conversion and utilization of CO2.Electroreduction driven by renewable electricity is an effective way for CO2 conversion and utilization.In this paper,new routes for biomass utilization,electrochemical conversion of CO2 coupled with biomass oxidative conversion were reviewed.The latest development of catalysts,reaction systems and reaction mechanisms for electrochemical reduction of CO2,as well as new oxidative conversion technologies of biomass and its derived alcohols and aldehydes on anodes were introduced.By coupling biomass oxidative conversion with CO2 electrochemical reduction,high-value chemicals can be produced with significant reduction of the net CO2 emission.Therefore,this paper can provide new ideas for the conversion of biomass and CO2.
