Microwave-assisted Pt–Co–Cr/C ternary compound preparation applied as a cathode catalyst for PEMFC

Preparation of Pt-based ternary catalyst as cathode material for proton exchange membrane fuel cell by solution route method

“…It can be concluded that Cr contained in the sample was Cr 2 O 3 compound. The existence of oxide phase might be explained as because chromium ion (+3) and cobalt ion (+2) are the most stable oxidation state and preparation process was conducted in an air atmosphere [17].…”

“…The solution route method can be used to synthesize nanoparticles of material with size smaller than those from the heat treatment process [12][13][14][15]. Moreover, preliminary introduction of functional groups on the carbon surface by treated with hydrogen peroxide was consequences in good dispersion of metal particles on carbon support [16,17].…”
