Embodiment Construction

[0048] The illustrative and non-limiting embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and the preparation method of the multi-component photocatalyst according to the present invention will be further described.

[0049] refer to figure 1 , according to the embodiment of the present invention, the preparation method of the novel multiple combination photocatalyst comprises the following steps:

[0050] Step A: collect the environmental data of the spraying site. In this step, measuring instruments can be used to collect environmental data in the site to be sprayed, and the type of data to be collected can be selected according to the special requirements of the customer. The on-site collection of environmental data can provide a basis for formulating the composition table of multi-component photocatalysts, so as to adapt to the types of harmful substances in different environments to prepare multi-componen...

Abstract

The invention discloses a preparation method for a multielement combined photocatalyst. The method includes: step A: gathering the environmental data of a spraying site; step B: according to the environmental data generating a dosage graph of water, a dispersant and a variety of photocatalysts for preparation of the novel multielement combined photocatalyst; and step C: preparing the novel multielement combined photocatalyst according to the dosage graph. On-site preparation of the photocatalyst by the method can solve the problems of long-term storage and transportation of multielement photocatalysts and different photocatalyst component requirements for different on-site environments, and at the same time the catalytic effect can be greatly improved.

Description

technical field [0001] The invention relates to the field of photocatalyst preparation, in particular to a method for preparing a multi-component photocatalyst. Background technique [0002] Photocatalyst is a general term for chemical substances that can play a catalytic role under the excitation of photons, such as: TiO 2 , Fe 2 o 3 、MoO 3 、Al 2 o 3 、WO 3 , V 2 o 3 , Tb 2 o 3 , SnO, CuO, NiO, ZnO, CdS, CdSe, SrTiO 3 Wait. [0003] Photocatalytic functional materials can generate photogenerated electrons, holes, and a variety of active groups on the surface under the excitation of light, so as to undergo continuous redox reactions. Various special functions such as super hydrophilicity and super water repellency. It has broad application prospects in environmental pollution control and governance. The degradation efficiency and rate of different photocatalysts for different organic volatiles are also different, even quite different. If different photocatalyst...
