【Abstract】 New advances in the research of tungsten compounds in some catalytic fields are introduced, including selective oxidation of alcohols, olefin metathesis reactions, selective catalytic reduction of NOx, biomass conversion,petroleum distillate refining, and fatty alcohol thiolation to alkyl mercaptans. Tungsten compounds, particularly oxides, sulfides and heteropoly complexes, can be used to prepare highly active and highly stable catalysts for a variety of important catalytic processes in business. Tungsten carbide and tungsten phosphide have unique catalytic properties as a novel catalyst. Due to the existence of a variety of oxidation states of tungsten from-2 to +6 and the structural diversity of tungsten compounds, there is endless potential for its application in the field of catalysis.更多还原
