Abstract

A method for treating a supported catalyst includes establishing shell-removal conditions for a supported catalyst that includes nanoparticles of a catalyst material on a carbon support. The nanoparticles each include a platinum alloy core capped in an organic shell. The shell-removal conditions include an elevated temperature and an inert gas atmosphere that is substantially free of oxygen. The organic shell is then removed from the platinum alloy core in the shell-removal conditions.
