摘要 大气中CO2的浓度增长而导致的温室效应已成为全球性问题,CO2分子的稳定性强,传统热解法转化CO2有一定的局限性,利用等离子体法将CO2资源化利用具有良好的前景。为此简要介绍了等离子体法转化CO2的基本原理和优势,讨论催化剂在转化过程中的作用。主要就近5年来国内外对介质阻挡放电(DBD)、滑动弧放电和微波放电等离子体转化CO2以及DBD、微波放电与不同催化剂相结合转化CO2的研究进行概述。基于目前的研究现状,分析了等离子体转化CO2技术存在的问题与挑战,提出利用等离子体技术将CO2与共氢反应物相结合生成高能效产品,权衡反应中CO2转化率和能量效率,对未来的发展方向进行展望。 The greenhouse effect caused by the increase of atmospheric CO2 concentration has become a global issue.CO2 molecule has strong stability,and the traditional pyrolysis method has certain limitations in transforming CO2.Application of plasma technology for recycling CO2 resource has exhibited good prospect.We briefly introduced the basic principle and advantages of CO2 conversion by plasma and discussed the role of the catalyst in the conversion process.Moreover,we summarized the recent(past five years)researches at home and abroad on dielectric barrier discharge(DBD),sliding arc discharge and microwave discharge plasma to convert CO2,as well as the studies of the combination of DBD,microwave discharge and different catalysts.Based on the current research status,the problems and challenges of plasma-converted CO2 technology were analyzed.It was proposed to use plasma technology to combine CO2 with co-hydrogen reactants to produce energy-efficient products,and to balance the CO2 conversion rate and energy efficiency in the future.The direction of development in the future was expected.
