Abstract
AbstractFructose is an important platform compound for the production of chemicals and renewable fuels. Here, the CeO2/ATP catalysts were developed for glucose isomerization in water. The effects of CeO2 loading, glucose concentration and the catalyst dosage to glucose ratio on the activity for the reaction were investigated. Glucose was easily transformed over ATP in the presence of CeO2, and the 10 % CeO2/ATP catalyst exhibited a good fructose yield of 36.4 %. Meanwhile, the reaction activity of glucose was affected by glucose concentration and the catalyst dosage to glucose ratio, and more fructose would be generated at lower glucose concentration, wherein the highest yield of fructose was obtained 39.2 % at 5 % of glucose solution with the catalyst dosage to glucose ratio of 0.1. In addition, the characterization resultsrevealed that CeO2 had a positive interaction with ATP on the adjustment of its structural properties and the amount and distribution of basic sites, and therefore facilitated glucose isomerization.
