Abstract

The acid catalysis of HNb3O8 sheets was presented through the formation and hydrolysis of ethyl acetate. HNb3O 8 exfoliated sheets were prepared by exfoliation and aggregation of layered HNb3O8 through soft-solution processing. HNb 3O8 exfoliated sheets were found to function as a strong BrØnsted acid catalyst, exceeding the activity of Nb2O 5•nH2O in the presence of water. The catalytic performance of HNb3O8 exfoliated sheets was attributed to the formation of bridging hydroxyl groups, Nb(OH)Nb.
