Abstract: A method for forming a carbon supported catalyst includes a step of providing a first carbon supported catalyst having a platinum-group metal supported on a first carbon support. Characteristically, the first carbon support has a first average micropore diameter and a first average carbon surface area. The first carbon supported catalyst is contacted with an oxygen-containing gas at a temperature less than about 450° C. for a predetermined period of time to form a second carbon supported catalyst, wherein the first carbon support or the second carbon supported catalyst is acid leached.

Abstract: A method for making tungsten-alloy nanoparticles that are useful for fuel cell applications includes a step of combining a solvent system and a surfactant to form a first mixture. A tungsten precursor is introduced into the first mixture to form a tungsten precursor suspension. The tungsten precursor suspension is heated to form tungsten nanoparticles. The tungsten nanoparticles are combined with carbon particles to form carbon-nanoparticle composite particles. The carbon-nanoparticle composite particles are combined with a metal salt to form carbon-nanoparticle composite particles with adhered metal salt, the metal salt including a metal other than tungsten. The third solvent system is then removed. A two-stage heat treatment is applied to the carbon-nanoparticle composite particles with adhered metal salt to form carbon supported tungsten-alloy nanoparticles. A method for making carbon supported tungsten alloys by reducing a tungsten salt and a metal salt is also provided.

Abstract: In an example method, a transition metal precursor is selected so its transition metal has a diffusion rate that is slower than a diffusion rate of silicon. An aqueous mixture is formed by dissolving the precursor in an aqueous medium, and adding silicon particles to the medium. The mixture is exposed to a hydroxide, which forms a product including the silicon particles and a transition metal hydroxide precipitate. The product is dried. In an inert or reducing environment, silicon atoms of the silicon particles in the dried product are caused to diffuse out of, and form voids in and/or at a surface of, the particles. At least some silicon atoms react with the transition metal hydroxide in the dried product to form i) a SiOx (0
