Abstract
Unsupported and silica-supported intermetallic compounds were prepared. Some characterizations revealed that they were composed of single-phase compounds having their specific surface. The catalytic activity of TiPt3 was higher than that of Pt for the H2–D2 equilibration and hydrogenation of ethylene. Ni3Sn gave higher selectivity than Ni for the partial hydrogenation of acetylene and the dehydrogenation of cyclohexane into benzene. RuTi/SiO2 and Pd3Bi/SiO2 gave much higher selectivity than their component pure metals in FT synthesis and the oxidative acetoxylation of toluene, respectively.
