Abstract
A method to achieve a conformal ultrathin film of platinum or one of its alloys on a substrate that can be economically used as a heterogeneous catalyst, such as automotive polymer electrolyte membrane (PEM) fuel cell catalyst. The method includes using a hydrogen plasma in platinum atomic layer deposition along with tungsten as a substrate or anchoring adhesive layer to assist platinum nucleation and deposition.
