Аннотация: Glucose is an industrially important valuable carbohydrate. 5-Hydroximethylfurfural (5-HMF) known as a platform molecule is a promising agent for chemical industry, manufacturing plastics and fuel production. Glucose and 5-HMF are usually produced from starch and sucrose in the presence of enzymes or soluble mineral acids as a cataПоказать полностьюlysts. Therefore one-pot hydrolysis-dehydration of the most abundant natural non-food cellulose polysaccharide in pure hot water over a solid acid catalyst seems the most attractive alternative way for the production of the main products. The development of highly active and stable solid acid catalyst for this process is still a great challenge. Oxides of niobium (V) or zirconium (IV) possessing acid or acid-base properties are stable in hot water and seem the most promising solid catalysts due to drawbacks of other type of catalysts (corrosion-activitis, high cost of noble metals, instability in hot water, etc.). To our knowledge, the NbOx/ZrO2 catalytic system was not been used before for direct cellulose transformation to glucose and 5-HMF in pure water. The aim of this work was to develop a solid ZrO2 acid catalyst containing niobium oxide for cellulose processing as well as to explore a promoting effect of niobium on catalyst activity.
