摘      要：A kind of inorganic organic hybrid 18 molybdodiphosphate nanoparticles ([(C 4H 9) 4N] 6P 2Mo 18 O 62 ·4H 2O) was firstly used as a bulk modifier to fabricate a three dimensional chemically modified carbon paste electrode (CPE) by direct mixing. The electrochemical behavior of the solid nanoparticles dispersed in the CPE in acidic aqueous solution was characterized by cyclic and square wave voltammetry. The hybrid 18 molybdodiphosphate nanoparticles bulk modified CPE (MNP CPE) displayed a high electrocatalytic activity towards the reduction of nitrite, bromate and hydrogen peroxide. The remarkable advantages of the MNP CPE over the traditional polyoxometalates modified electrodes are their excellent reproducibility of surface renewal and high stability owing to the insolubility of the hybrid 18 molybdodiphosphate nanoparticles.
