Nano-TaOxNy particles synthesized from oxy-tantalum phthalocyanine: how to prepare precursors to enhance the oxygen reduction reaction activity after ammonia pyrolysis?

Nano-TaOxNy oxygen reduction reaction (ORR) catalysts were supported on multi-walled carbon nanotubes (MWCNTs) using two-step pyrolysis of oxy-tantalum phthalocyanine (TaOPc). For the first time, slightly oxidized Ta sub(3)N sub(5) has been experimentally proposed to be ORR active in acidic media.
