【Abstract】 The structures, physicochemical properties and catalytic applications of niobic acid and niobium oxide are reviewed in thi s paper. Both niobic acid and niobium oxide can be used as either catalyst, promoter or support in the heterogeneous catalytic reactions, such as selective oxidation, hydration, hydro lysis, alkylation, dehydrogenation and hydrogenation, because of their uniqu e acidic and redox properties.更多还原
