摘要：

The inorganic-organic hybrid polyoxometalates (POMs), (pbpy)(4)H[PMo12O40(VO)] (1) and (pbpy)(4)H-4[SiMo12O40] (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.
