Transition metal carbides and nitrides have attracted attention as possible replacements for platinum group catalysts. Most of the work has been carried out with single-metal compounds. The authors report the preparation of two new bimetallic compounds, V-Mo and V-W oxynitrides, obtained by nitriding oxide precursors with ammonia gas via a temperature-programmed reaction. The bimetallic oxide precursors are prepared by conventional solid state reaction using commercial V, Mo, and W oxides. The oxynitrides thus obtained adopt a face-centered cubic crystal structure. They have high specific surface areas (74 and 62 m{sup 2} g{sup {minus}1}), and their pyrophoricity suggests high surface activity.
