Abstract

The invention discloses a fullerene / anion clay compound photocatalyst and a preparation method and application thereof. The fullerene / anion clay compound photocatalyst is prepared from fullerene and anionic clay according to the mass ratio between 0.1 to 100 and 5 to 100 in a compounding mode. The preparation method of the fullerene / anion clay compound photocatalyst mainly comprises the first step of preparing dispersed fullerene solution, the second step of preparing a fullerene / anion clay composite material through a dynamic urea method, and the third step of conducting high-temperature vacuum calcination on the fullerene / anion clay composite material to obtain the fullerene / anion clay compound photocatalyst. The prepared fullerene / anion clay composite material can be applied to treatment of organic pollution, wherein the organic pollutant-bisphenol A is degraded through photo-catalytic oxidation.

Description

technical field [0001] The invention relates to the technical field of composite materials with adsorption and visible light catalytic properties, in particular to a fullerene / anion clay composite photocatalyst that can be used to treat bisphenol A pollution under visible light, and its preparation method and application. Background technique [0002] Bisphenol A (Bisphenol A, abbreviated as BPA), a chemical raw material, is a known endocrine disruptor (environmental hormone), with two phenolic functional groups. Bisphenol A is used to make epoxy resin, polycarbonate, polyphenol oxide, etc. It is widely used in daily life plastic products, including drinking water bottles, baby bottles, etc. At the same time, it is also applied to the coating of the metal surface, so that the canned food is not easy to deteriorate and deteriorate. However, BPA can lead to endocrine disorders, threatening the health of fetuses and children. Obesity from cancer and metabolic disorders is al...
