| Abstract: | Inorganic-organic hybrid Keggin-type germanomolybdate nanoparticles (C_2H_5)_4N]_4GeMo_(12)O_(40)(GeMo_(12)) was firstly used as a modifier to fabricate a three-dimensional bulk-modified carbon paste electrode (CPE) by direct mixing. The electrochemical behavior of the GeMo_(12)-CPE was studied in acidic aqueous solution. The results show that the GeMo_(12)-CPE kept the electrochemical activity of the germanomolybdate and surface-renewability of the CPE. The GeMo_(12)-CPE not only showed good electrocatalytic activity toward the reduction of nitrite and bromate, but also possesses excellent stability, which is owed to the insolubility and strong adsorption on the graphite powder of the hybrid germanomolybdate nanoparticles. |
