| Abstract: | Microelectrode techniques were used for the study of electrocatalytic behaviors of powdered catalysts. Ultrathin layer of fine catalyst powder was intercalated into the surface layer of soft conductive plastic sheet made from acetylene black and PTFE binder. Microelectrodes of such construction were successfully employed in the study of reversible and irreversible electrode reactions. Experimental results indicated that microelectrode with ultrathin layer of surface intercalated power could be a powerful tool for the study of electrocatalytic behaviors of powder catalysts. |
