摘要: Phosphoric acid treated niobic acid (NbP) was used for the dehydration of xylose to furfural in biphasic solvent system, which was found to exhibit the best performance among the tested catalysts. The excellent performance of NbP could be explained by the better synergistic cooperation between Brönsted and Lewis acid sites. Moreover, NbP showed good stability and no obvious deactivation or leaching of Nb could be observed after six continuous recycles.
