ELECTRONIC CONDUCTIVE POLYMERS DOPED BY HETEROPOLYANIONS, THEIR PREPARATION PROCESS AND THEIR USE IN CHEMICAL AND ELECTROCHEMICAL CATALYSIS

摘要

DESCRIPTIVE The invention relates to an electronic conductive polymer doped by the anions of a heteropolyacid of formula: Hn(XMyVy,Oz) in which n, y, y' and z are such that 2?n?6, 6?y?18, 0?y'?12, 24?z?70 and 6?y+y'?18, X being an element such as P or Si and M is Mo or W. These polymers can be prepared by chemical or electrochemical oxidation from a solution containing the heteropolyacid and the monomer able to form an electronic conductive polymer by oxidation, e.g. pyrrole, thiophene, aniline, paraphenylene diamine, acetylene, benzene and their substituted derivatives. The doped electronic conductive polymer makes it possible to reduce the protons of a solution as is shown by curve (1) of the attached Fig. 2. (Fig. 2)
