In this study, a carbon supported oxynitrides catalyst with ultra-low Pt concentration (2 wt%,
Pt-ON/C) is synthesized from Co (NO 3) 2⋅ 6H 2 O,(NH 4) 6 Mo 7 O 24⋅ 4H 2 O and PtCl 4
precursors by using NH 3 as reducing agent and nitrogen source. It is investigated as
oxygen reduction reaction (ORR) catalysts for proton exchange membrane (PEM) fuel cells
and compared to conventional 2 wt% Pt/C (ETEK) catalyst. Electrochemical and physical
properties of both materials were characterized in detail. Pt-ON/C shows competitive ORR …
