Carbon supported Ir nanoparticles modified and dealloyed with M (M = V, Co, Ni and Ti) as anode catalysts for polymer electrolyte fuel cells

Very active carbon-supported Ir modified with transition metal M catalysts (M = V, Co, Ni and Ti) were synthesized by an ethylene glycol (EG) reduction method as novel, suitable anode electrode materials for polymer electrolyte membrane fuel cells (PEMFCs) applications. IrM nanoparticles showed a narrow particle size distribution centered around 2–3 nm, and were uniformly dispersed on Vulcan XC-72 supports. Investigation of the catalytic …
