摘　　要：首次采用化学法合成的Keggin型钼钒磷酸掺杂的聚吡咯杂化材料做修饰剂制得了本体修饰的碳糊电极,并研究了该修饰电极在酸性水溶液中的电化学行为。结果表明该修饰电极充分保持了钼钒磷酸的电化学活性和碳糊电极表面可更新的特点,不仅对过氧化氢和溴酸根的还原具有很好的电催化活性,而且还具有优良的稳定性。Keggin--type molybdovanadoposphate (PMo_(11) VO_(40) )--doped polypyrrole (PPy) prepared by chemical syntheses is firstly used as a modifier to fabricate a bulk--modified carbon paste eletrode(CPE) by direct mixing. The electrochemical behavior of the PMo_(11) VO_(40)--PPy--CPE not only keeps the electrochemical activity of the molybdovanadophosphate and surface--renewability of the CPE but also shows high electro- catalytic activity toward the reduction of hydrogen peroxide and bromate. In addition,the PMo_(11) VO_(40)-PPy-- CPE possesses excellent stability.
