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.
