| Abstract: | The inorganic‐organic hybrid polyoxometalates (POMs), (pbpy)4HPMo12O40(VO)] ( 1 ) and (pbpy)4H4SiMo12O40] ( 2 ) (pbpy=5‐phenyl‐2‐(4‐pyridinyl)pyridine), have been synthesized and were, respectively, used as a solid bulkmodifier to fabricate a three‐dimensional bulk‐modified carbon paste electrode (CPE) by direct mixing. The electrochemical behavior and electrocatalysis of 1 and 2 modified CPE ( 1 ‐CPE and 2 ‐CPE) have been studied in detail. Both 1 ‐CPE and 2 ‐CPE show remarkable stability that can be ascribed to the doped organic conjugated pbpy, which is very important for practical applications in electrode modification. |
