Abstract

The invention belongs to the technical field of photocatalytic materials, and discloses a 4-phenoxyphenol doped carbon nitride photocatalyst and a preparation method and application thereof. The photocatalyst is prepared by the following steps: respectively dispersing dicyandiamide and 4-phenoxyphenol into absolute ethyl alcohol, mixing, magnetically stirring and ultrasonically treating at room temperature, then magnetically stirring, heating and evaporating to dryness at 60-80 DEG C, putting the obtained solid into a muffle furnace, calcining at 540-550 DEG C at a heating rate of 5-6 DEG C/min, cooling to room temperature, and grinding with an agate mortar to obtain a series of PCN catalysts. The preparation method adopts a thermal polymerization method, is simple in synthesis process andgood in repeatability, and has basic conditions for large-scale production. The PCN 0.07 catalyst provided by the invention has good catalytic performance, and the PCN 0.07 catalyst can degrade IDM under the light of different light sources.

Description

technical field [0001] The invention belongs to the technical field of photocatalysis, and in particular relates to a 4-phenoxyphenol-doped carbon nitride (PCN) and its preparation method and application. Background technique [0002] As a non-steroidal anti-inflammatory drug, indomethacin is a non-corticosteroid anti-inflammatory and analgesic drug with strong effects. It inhibits the synthesis of cyclooxygenase and then inhibits the production of prostaglandins and other steroids. Thereby play the role of anti-inflammatory and analgesic, and its chemical properties are stable. Due to the lack of effective degradation of it in traditional sewage treatment plants, the concentration of indomethacin in the wastewater entering and leaving the treatment plant remains basically unchanged, and its content in natural water bodies shows a cumulative increase, which is harmful to ecological security and human health. There is a potential threat. Therefore, the environmental behavio...
