Abstract

The invention relates to a preparation method of a water-phase cerium fluoride microparticle and application thereof, and belongs to the technical field of photocatalysis. The preparation method has the advantages that by using ceric ammonium nitrate or cerous nitrate as a cerium source, and using ammonium hexafluorotitanate or ammonium fluoride as a fluorine source, the water-phase cerium fluoride microparticle with good dispersivity is prepared by a simpler and mild preparation technology; the good phtocatalysis property is realized under the visible light condition, and the application field of cerium fluoride is widened.

Description

technical field

[0001] The invention belongs to the technical field of photocatalysis, and in particular relates to a preparation method and application of water-phase cerium fluoride particles. Background technique

[0002] Rare earth semiconductor materials have high chemical activity, chemical stability, and thermal stability, and have received extensive attention in the degradation of organic pollutants under visible / ultraviolet light. Some rare earth compounds containing cerium, especially cerium oxide, have attracted much attention in the field of visible light catalysis. The reported cerium-containing rare earth compounds are CeO 2 And composite materials based on it are the main category, and its photocatalytic degradation efficiency of pollutants is better than that of commercial titanium dioxide (P25). Cerium fluoride (CeF 3 ) As another class of cerium-containing compounds, it is currently mostly used in wear-resistant materials, sensors, optical thin films, up...
