A catalytic powder comprising a plurality of support metal particles with a porous
coating (12) surrounding the metal particles (11), the porous coating
comprising either an electrocatalytic metal or an electrocatalytic metal continuous
phase in admixture with a particulate material (14). An electrode made with
the catalytic powder and a method to make the electrode is also disclosed. The
present invention is advantageous because the porous coating mixture is first applied
to a powder rather than being applied directly to a metal substrate, thereby creating
a large internal surface area on the electrode and accordingly, lower overpotential requirements.
