The H2WO4-Pt/ZrO2 combination catalyses the direct conversion of cellulose into ethanol with a yield of 32% in an aqueous medium under H2. H2WO4 mainly facilitates the cleavage of C-C bonds in the glucose unit, while Pt/ZrO2 with an appropriate fraction of Pt0 and Pt2+ promotes the formation of ethanol through a selective C-O bond activation.
H2WO4-Pt/ZrO2组合在氢气存在下于水介质中催化纤维素直接转化为乙醇，产率为32%。H2WO4主要促进葡萄糖单元中碳-碳键的断裂，而具有适当比例Pt0和Pt2+的Pt/ZrO2通过选择性碳-氧键活化促进乙醇的形成。
