发展了软嵌式粉末微电极方法研究粉末材料的电催化行为, 制备电极时将超薄层催化剂粉末软嵌入用聚四氟乙烯乳剂和乙炔黑制成的防水导电膜上, 采用这种电极研究了各种粉末催化剂在可逆及不可逆反应中的电催化行为. 实验结果表明, 采用软嵌式粉末微电极可以利用微盘电极技术的种种优点而成为研究粉末催化剂电化学行为的有力工具.

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.
