Abstract

Molybdenum oxynitride was prepared by hydrazine reduction of MoO<subscript>3</subscript> at moderate temperatures. The anhydrous condition was favorable to production of amorphous molybdenum oxynitride, and the presence of hydrogen favored the reduction of Mo<superscript>6+</superscript> and Mo<superscript>4+</superscript> species to Mo<superscript> δ+</superscript> (0 < δ < 4) species. These molybdenum oxynitrides exhibited activity for hydrogenation which depended on the amount of Mo<superscript> δ+</superscript> (0 < δ < 4) species produced under reaction conditions. The amorphous molybdenum oxynitride MoO<subscript>1.83</subscript>N<subscript>0.36</subscript> catalyst showed a good catalytic activity, selectivity, and resistance to poisoning of H<subscript>2</subscript>S for liquid-phase hydrogenation of longer-chain alkadienes.
