As reported at ScienceDaiZy in 2007, Strasser and his colleagues discovered an alloy of copper (Cu), cobalt (Co) and platinum (Pt) that exceeded even pure platinum s catalytic activity for the reduction of oxygen (one of the important reactions taking place in fuel cells). The material consists of tiny particles called nanoparticles, described in...

Cobalt porphyrins and phthalocyanines were used as precursors for preparation of carbon supported cobalt catalysts that displayed high activity in reduction of oxygen in fuel cells [9-12], These samples were prepared by deposition of cobalt phtalocyanine on active carbon following by heat treatment at 650-700°C in an inert atmosphere providing formation of Co-N structure deposited on active carbon.
