Abstract
In the present invention, platinum and alloying metal precursor ions are reduced to platinum alloy particles using specifically prepared reducing agents, under controlled reaction temperature and pH conditions, with uniform dispersion and high uniformity in nano-scale sizes adhered onto carbon nanotubes; besides, the compositions of prepared Pt alloy electrocatalysts can be put under control as desired.
