Nickel-molybdenum bimetallic catalyst and preparation method and application thereof

Abstract

According to the preparation method of the nickel-molybdenum bimetallic catalyst disclosed by the invention, Mo is doped in the prepared nickel-molybdenum bimetallic catalyst, so that the oxidation current of the nickel-based catalyst for electro-catalysis of 5-hydroxymethylfurfural can be effectively improved, and the oxidation current is 4.3 times that of a pure nickel-based catalyst prepared under the same condition. The invention also discloses an application of the nickel-molybdenum bimetallic catalyst grown on foamed nickel in electrocatalytic oxidation of 5-hydroxymethylfurfural, under 1.4 V, the conversion rate of 5-hydroxymethylfurfural can reach 99.7%, the yield of 2, 5-furandicarboxylic acid can reach 98.5%, and the Faraday efficiency can reach 98.5%. The catalyst can also oxidize small biomass organic molecules such as glucose, benzyl alcohol, ethanol and furfuryl alcohol, and has excellent universality.
