随着石油工业的技术进步，铌化合物可直接作为催化剂活性组分、助剂和载体，用于催化多种化学反应。草酸铌铵具有很好的水溶性，是近年来迅速发展起来的一种新型石油化工催化剂的前体，享有“绿色催化剂”之称。同时，草酸铌铵作为一种可溶性铌的化合物，在功能材料制备方面越来越得到重视，草酸铌铵可以用于介电材料、铁氧体的制备。

With advancements in the petroleum industry, niobium compounds can serve directly as active catalytic components, promoters, and supports for a variety of chemical reactions. Ammonium niobium oxalate, known as a "green catalyst," boasts excellent water solubility and serves as a precursor for a new type of petrochemical catalyst that has seen rapid development in recent years. Furthermore, as a soluble niobium compound, it is gaining increasing importance in the preparation of functional materials, such as dielectric materials and ferrites.
