Abstract

original image

High alcohol tolerance: A Pt/CoSe2 nanobelt cathode catalyst for direct methanol fuel cells was prepared by in situ loading of Pt nanoparticles on CoSe2/diethylenetriamine nanobelts through a polyol reduction approach. The resulting functionalized nanobelts (see picture) exhibit high activity in the four-electron oxygen reduction reaction and are highly methanol tolerant.
