Abstract
The invention discloses a method for preparing a nickel-tungsten bimetallic carbide catalyst by an organic-inorganic hybrid route and application of the nickel-tungsten bimetallic carbide catalyst, and belongs to the technical field of material preparation and application. The method is characterized in that pure phase Ni6W6C and W2C and Ni6W6C composite materials with different Ni contents are synthesized by the organic-inorganic hybrid route and both exhibit a nano-particle stacking and aggregation form with a length of about 0.3-4 mu m and a diameter of about 300-900 nm. The BET specific surface area of the nickel-tungsten bimetallic carbide ranges from 17.6 m<2>/g to 15.7 m<2>/g. Compared with the traditional arc melting method and temperature programmed reduction method, the method provided by the invention has the advantages of low temperature, simple operation, energy saving, small product particles and less surface carbon pollution. The industrial application prospect is optimistic, the prepared bimetallic carbide catalyst can be applied to hydrogenation, hydrogenolysis, dehydrogenation, deoxygenation, isomerization, methane syngas, water-gas shift, hydrogen evolution reaction and catalyst support and the like.
