Preparation method of organic pollutant photolysis catalyst

Abstract

The invention discloses a preparation method of an organic pollutant photolysis catalyst. The preparation method is characterized by comprising steps as follows: regular ceramic is taken as carriers, are subjected to array hole formation with laser and activating treatment with potassium permanganate and then ultrasonically load sol-gel containing BiVO4, TiO2 and graphene, a product is subjected to vacuum drying and is subjected to high-temperature calcination finally, and industrial organic pollutant photolysis catalyst based on BiVO4-TiO2-graphene loaded regular ceramic is prepared. The photolysis catalyst can simultaneously release molecular radicals through plasma discharge and produce superoxide radicals and hydroxyl radicals through photocatalysis under radiation of a plasma emission (UV) light, thereby efficiently and thoroughly degrading toxic, harmful and stink industrial waste gas and industrial organic pollutants containing sulfur, nitrogen, ammonia, phenol, PAHs (polycyclic aromatic hydrocarbons), pesticides, antibiotics, viruses, bacteria and the like.

Description

technical field [0001] The invention relates to a preparation method of a photodegradation catalyst, in particular to a preparation method of an industrial organic pollutant photodegradation catalyst with regular ceramics as a carrier. Background technique [0002] As we all know, most of the organic pollutants in industrial waste gas and wastewater have odorous, toxic, harmful and teratogenic properties, which have become the main culprits affecting people's health and atmospheric smog. At present, the technologies for treating such industrial waste gas and wastewater mainly include: activated carbon adsorption method, photocatalysis method, plasma method, catalytic combustion method and biological method, etc. Most of the technological processes adopted are a series of different physical, chemical and biological processes in series. and other processing techniques. For example, take photocatalyst as an example, or use pure TiO 2 Photocatalyst is an active component, resu...

Problems solved by technology

For example, take photocatalyst as an example, or use pure TiO 2 Photocatalyst is an active component, resulting in photocatalyst activity only corresponding to ultraviolet light, and TiO 2 Photocatalyst electron-hole recombination is fast, electron utilization rate is low, photocatalyst activity is low, and industrial organic pollutant molecules with large bond energy cannot be degraded quickly
