摘要:

CO2电化学还原,特别是与间歇性的可再生电能相结合转化为液体燃料提供了一条很有前景的将电能存储为化学能的途径,它既降低了人们对化石燃料的依赖,又减轻了因人类活动而排放的CO2对地球的不利影响.尽管CO2转化为燃料本身不是一个新概念,但在过去的30多年里该领域的研究也没有很大的进展.这主要是由于结构型电催化剂的开发、以及可有效收集反应物和分离产物的膜组件的开发存在很大的挑战.本文总结了CO2催化转化的最新进展,提出了制备高附加值燃料的挑战和未来的方向.

Abstract:

The electrochemical reduction of CO2 into liquid fuels especially coupling with the intermittent renewable electricity offers a promising means of storing electricity in chemical form, which reduces the dependence on fossil fuels and mitigates the negative impact of anthropogenic CO2 emissions on the planet. Although converting CO2 to fuels is not in itself a new concept, the field has not substantially advanced in the last 30 years primarily because of the challenge of discovery of structural electrocatalysts and the development of membrane architectures for efficient collection of reactants and separation of products. This overview summarizes recent advances in catalytic conversion of CO2 and presents the challenges and future directions in producing value-added fuels.
