ABSTRACT:
Quasi-crystalline aluminum alloy ultrafine particles are produced by a gas-phase reaction and consist of at least one alloy element from the group of V, Cr, Mn, Fe, Co, Ni, Cu and Pd, for example palladium (Pd) in an amount represented by 20 atomic %.ltoreq.Pd.ltoreq.30 atomic %, and the balance of aluminum. Palladium has a catalyst power, and the ultrafine particles have a large specific surface area, because they have a particle size d.ltoreq.200 nm. Such ultrafine particles have a high catalytic activity in a methanol decomposing reaction and also have a good retention of catalytic activity.
