Biomass-based carbon-loaded metal oxide catalyst as well as preparation method and application thereof

The invention discloses a biomass-based carbon-loaded metal oxide catalyst as well as a preparation method and application thereof, and belongs to the field of chemistry and chemical engineering. The catalyst provided by the invention is prepared by mixing sugar or solid carbon with a composite salt solution and then roasting. The solid carbon is prepared from the sugar through raw material roasting. The composite salt solution is formed by mixing a first metal oxide, a second metal oxide and a solvent. The catalyst disclosed by the invention has the advantages of good target product selectivity, easiness in reuse and regeneration and the like, and the energy consumption of product separation can be remarkably reduced. In addition, a carrier of the catalyst is derived from biomass such as saccharides and is easy to obtain, and the catalyst is simple in preparation method, high in activity and easy to recover. 本发明公开了一种生物质基碳负载金属氧化物的催化剂及其制备方法和应用，属于化学化工领域。本发明中的催化剂是由糖或固体碳与复合盐溶液混合后，再经过焙烧制得。所述固体碳是由所述糖经过原料焙烧制得。所述复合盐溶
