Abstract
A method for preparing hollow platinum or platinum-alloy catalysts includes a step of forming a plurality of low-melting-point metal nanoparticles. A platinum or platinum-alloy coating is then deposited onto the low-melting-point metal nanoparticles to form platinum or platinum-alloy coated particles. The low-melting-point metal nanoparticles are then removed to form a plurality of hollow platinum or platinum-alloy particles.
