摘要

利用无溶剂法制备了一种组装MOFs材料,并在煅烧过程中加入Cu和Bi两种金属,通过SEM、XRD、TEM和XPS等表征证明Cu和Bi已成功负载。利用Bi对C₁产物的高活性,增强Cu催化剂对反应中间体的吸收,最大C₂H₄法拉第效率可达44.7%,比不加Bi的催化剂对C₂产物的选择性提高了约18%。

Abstract

An assembled MOFs material is prepared by a solvent-free method,which is added with Cu and Bi in the calcination process.The material is tested by mean of SEM,XRD,TEM and XPS,and it is verified that Cu and Bi are successfully loaded.High activity of Bi on C₁ products is utilized to enhance the absorption of Cu catalyst to reaction intermediates,the maximum Faraday efficiency of C₂H₄ can reach 44.7%,which is about 18% higher than that by pure Cu catalyst for C₂ products.
