文摘

Molybdenum oxynitride was prepared by hydrazine reduction of MoO₃ at moderate temperatures. The anhydrous condition was favorable to production of amorphous molybdenum oxynitride, and the presence of hydrogen favored the reduction of Mo6+ and Mo4+ species to Mo+ (0 + (0 _1.83N_0.36 catalyst showed a good catalytic activity, selectivity, and resistance to poisoning of H₂S for liquid-phase hydrogenation of longer-chain alkadienes.
