Carbon dioxide reduction on platinum and carbon felt electrodes coated with polymeric films obtained by oxidative electropolymerization of pyrrole-containing Re(L)(CO)3Cl complexes, where L is a 2,2'-bipyridine, has been investigated. Catalytic activities of modified electrodes prepared by polymerization of differently substituted complexes have been compared, on the basis of cyclic voltammetry and
已经研究了铂和碳毡电极上的二氧化碳的还原,该铂和碳毡电极上涂覆了聚合物膜,该聚合物膜是通过含吡咯的Re(L)(CO)3 Cl配合物(其中L为2,2'-联吡啶)的氧化电聚合获得的。在循环伏安法和制备规模实验的基础上,对通过不同取代的配合物的聚合反应制备的修饰电极的催化活性进行了比较。将CO 2电催化还原为CO的电流产率很高,并且最大的催化效率对应于最佳的膜厚度。
