The invention discloses a vermiculite-containing TiO2-C3N4 photocatalyst and a preparation method thereof. The photocatalyst is specifically prepared from the following raw materials in parts by weight: 10 to 20 parts of vermiculite, 3 to 7 parts of titanium isopropylate, 5 to 10 parts of urea, 2 to 5 parts of citric acid, 0.5 to 3 parts of diluted hydrochloric acid, 0.2 to 3 parts of sodium carbonate, 2 to 5 parts of polyethylene glycol-8 and a proper amount of deionized water. The material is a photocatalyst combined with physical and chemical adsorption and photocatalytic degradation technologies and under the combined action of vermiculite and a TiO2-C3N4 catalyst, not only has good capabilities of purifying air and degrading organic matters, but also has the characteristics of environmental friendliness, stable properties, antibacterial property, ultraviolet resistance and the like. 本发明公开了一种含有蛭石的TiO2-C3N4光触媒剂及其制备方法，所述光触媒剂具体包括如下以重量份数计的原料：蛭石10-20份、异丙醇钛3-7份、尿素5-10份、柠檬酸2-5份、稀盐酸0.5-3份、碳酸钠0.2-3份、聚乙二醇-82-5份以及适量
