In the preparation of new catalytic materials, maximizing the surface area is important to minimize the amount of catalyst needed. This study is concerned with the synthesis of high surface area molybdenum and vanadium nitrides by the reaction of oxide and ammonium oxide precursors with ammonia. The reactions have been followed using thermogravimetric analysis (TGA) and high temperature x-ray diffraction (XRD) to determine reaction intermediates, while the development of surface area was investigated by interrupting the TGA experiments and measuring the surface area using the BET method. 102 refs., 37 figs., 10 tabs.
