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.
