The invention relates to a nitrogen oxide nanoparticle photocatalyst and application thereof, wherein the nitrogen oxide nanoparticle photocatalyst is A a B b O c N d The nitrogen oxide is a nitrogen oxide with the content of 0-5, B, c and d, A is one of calcium, strontium, barium, lanthanum or sodium, B is one of titanium, tantalum or niobium, and is prepared by the following steps: preparing a metal oxide precursor by a coprecipitation method: the metal oxide precursor is ammoniated and burned to prepare perovskite nitrogen oxide, and the nitrogen oxide nano-particle photocatalyst is obtained after aqua regia treatment. After the photocatalyst nano particles are loaded with a proper cocatalyst, the photocatalyst nano particles show excellent capability of photocatalytic water decomposition hydrogen production and organic pollutant formaldehyde photodegradation under sunlight. |
