摘要
围绕调控型钙钛矿在脱除烟气汞领域的研究进展进行系统综述,比较了调控前后钙钛矿脱汞差异,重点总结了 A位、B位以及AB位共同调控钙钛矿脱汞的研究现状,讨论了活性位点、氧化物种和反应参数等因素对脱汞性能的影响差异,归纳了不同类型钙钛矿对应的脱汞路径及反应机理.提出了继续发展调控型钙钛矿是摆脱脱汞过程对HCl的依赖、克服脱汞材料抗硫性和抗水性差等缺点的可行策略.
Abstract
This paper systematically reviews the research status of perovskite in the field of mercury removal from flue gas,compares the differences of perovskite mercury removal before and after regulation,summarizes the application achievements of A-position,B-position regulation and AB position co-regula-tion of perovskite mercury removal,discusses the influence of active sites,oxidation species and reaction parameters on mercury removal performance,and summarizes the corresponding mercury removal paths and reaction mechanisms of different types of perovskite,compares and analyzes the advantages and disad-vantages of three mercury removal technologies.It is proposed that the continuous development of regula-ted perovskite is a feasible strategy to get rid of the dependence of mercury removal on HCl and overcome the shortcomings of poor sulfur resistance and water resistance of mercury removal materials.
