Hydroxyapatite-based photocatalyst with full-spectrum response capability as well as preparation method and application thereof

The invention discloses a hydroxyapatite-based photocatalyst with full-spectrum response capability and a preparation method and application thereof, the photocatalyst is prepared by the following steps: by taking CaCl2, (NH4) 2HPO4 and organic saccharides as raw materials, modifying saccharide molecules to the surface of hydroxyapatite through a coprecipitation method, and calcining the saccharide-modified hydroxyapatite, the photocatalyst is of a rod-like structure, and the surface of carbohydrate modified hydroxyapatite is coated with graphite carbon. The photocatalyst is uniform in morphology and size, large in specific surface area and stable in property, the preparation method is simple in step and environmentally friendly, the full-spectrum response capacity is achieved, the photocatalytic activity of the photocatalyst is greatly improved, and the photocatalyst has good application prospects in photocatalytic degradation of organic pollutants. 本发明公开了一种具有全光谱响应能力的羟基磷灰石基光催化剂及其制备方法与应用，该光催化剂是以CaCl2和(NH4)2HP
