Abstract

The invention relates to a method for preparing polypyrrole doped molybdate, which comprises the following steps: 1) using an inert electrode as an anode, an inert electrode as a cathode, mixed aqueous solution containing sodium molybdate and pyrrole as an anolyte, acid solution, alkaline solution or salt solution as the catholyte, in the double-chamber electrolyzer with cationic membrane as diaphragm, controlling the temperature from the room temperature to 90 DEG C, and using constant-current electrolysis or constant-voltage electrolysis to electrolyze; 2) after electrolysis, drying the solution obtained in the anode chamber at 80 DEG C to 120 DEG C; filtering and cleaning the resulting powder and drying at 80 DEG C to 120 DEG C and then cooling to room temperature to obtain a sample of polypyrrole doped molybdate. The prepared polypyrrole doped molybdate sample is pure, free of impurities, and evenly distributed, and the follow-up treatment is simple, the investment is small and the synthesis amount is large, which solves the problems of product heterogeneity, low stability, high cost, complex operation, and others in the process of preparing polypyrrole doped molybdate.
