Abstract
Catalytic particles with an inert, corrosion resistant support material are provided with a catalyst finely dispersed in a matrix of an insoluble electrically conducting polymer formed in situ on each particle of inert support material. The inert support particles are catalytically activated by: PA0 (a) wetting them with a solution containing an inorganic precursor compound for the catalyst and an organic precursor compound for the insoluble polymer matrix, PA0 (b) drying the particles, and PA0 (c) heat treating them to convert the precursors to the catalyst dispersed in the polymer matrix. An electrode, e.g. an oxygen-evolving anode, is produced by either fixing the catalytic particles to an electrode base, e.g. lead, or by consolidating the catalytic particles into a porous electrode body.
