Application of Niobic Acid in Catalysis

Niobic acid and compounds containing niobium are applied in a wide range of catalysis fields for their unique acidic property and thermal stability. Niobic acid as a solid catalyst can be directly applied in the hydrolysis, esterification, condensation and alkylation reaction etc. Compounds containing niobium, as a supporter loaded metal, can be used in Fischer-Tropsch synthesis, hydrogenation and oxidation reactions etc. As a supported catalyst, it can be loaded to different type of catalysts. Compounds containing niobium can also be widely used in a variety of chemical reactions as assistant or photocatalysts. The niobium catalysts had high catalytic activity, selectivity and long service life, so the development of new type of niobium catalysts has a good prospect.
