摘要
将二氧化碳(CO_2)转化为高附加值的化学品和燃料被认为是21世纪的巨大挑战,如何高效活化CO_2是将其资源化利用的重要环节。针对常见的CO_2转化策略,如CO_2分解反应、CO_2与氢化合物(氢气、甲烷、水)反应,讨论了催化转化、电化学还原、太阳能热、等离子转化技术以及各新技术协同催化技术在CO_2活化转化领域中最新应用进展。从转化率和能效的角度强调了多学科交叉的重要性,并对未来CO_2转化发展进行了展望。
CO2 conversion into value-added chemicals and fuels is considered as one of the greatest challenges of the 21 st century. The important part of its resource utilization is to find method and technology to effectively and efficiently activate CO2 molecule. In general,the common chemical conversion strategies,including pure CO2 splitting and conversion of CO2 with hydrogen source compound like hydrogen（ H2）,methane（ CH4） and steamed water（ H2O）,have been briefly reviewed. In this paper,after exploring traditional thermodynamic limitation,several novel technologies are investigated,such as electrochemical reduction,solar thermochemical,photochemical and plasma technology,either with or without catalysts,as well as their great potentials in recent years applied in the CO2 conversion fields. Conversion rate and energy efficiency were used to demonstrate the importance of the muti-disciplinary efforts. Finally,the challenge and prospects for the further development of CO2 conversion has been presented.
