Abstract

See full text

A catalyst for use in at the anode of direct methanol fuel cells is made from nanoparticles having a core-shell structure. The core is an alloy of platinum and gold. The core is surrounded by a first shell of ruthenium and a second shell containing a ternary alloy of platinum, gold, and ruthenium. The catalyst can be made by a reverse-micelle method or by a single-phase scalable method. The catalyst is highly stable under conditions of use and resists dissolution of ruthenium or platinum.
