The invention discloses a niobium compound photocatalyst as well as a preparation method and application thereof, and belongs to the technical field of photocatalysts. The preparation method comprises the following steps: adding a niobium-containing compound into glucose-urea in a molten state, continuously stirring for 10-60 minutes after the niobium-containing compound is dissolved, then transferring a mixed solution into a hydrothermal reaction kettle, reacting for 12-48 hours at 180-220 DEG C, grinding the obtained mixture, and roasting for 3-8 hours in an inert atmosphere at 300-500 DEG C to obtain the catalyst. The method disclosed by the invention is simple to operate, the catalyst is stable in structural property and easy to repeat, and the obtained niobium compound (Nb2O5@C) has excellent catalytic activity and can be prepared on a large scale. 本发明公开了一种铌类化合物光催化剂及其制备方法和应用，属于光催化剂技术领域。所述制备方法包括如下步骤：将含铌化合物加入到熔融状态的葡萄糖-脲中，待其溶解后，继续搅拌10-60min，然后将混合溶液转移至水热反应釜中，于180-220℃反应12-48h，将得到的混合物研磨后于300-500℃惰性气氛中焙烧3-8h，即
