Problems solved by technology

[0005] In the actual production process, since the photocatalyst activated carbon needs to be illuminated, when the photocatalyst activated carbon is placed in a closed environment and the photocatalyst activated carbon is located inside the part, the degree of illumination of the photocatalyst activated carbon is greatly restricted, which affects the redox of the photocatalyst activated carbon. reaction

Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below.

[0025] A preparation method of photocatalyst activated carbon, is characterized in that, comprises the following steps:

[0026] Step A: Process ilmenite to form a thin strip or flat structure, and place the processed ilmenite in a container. The main component of ilmenite is FeTiO 3 and TiO 2 , choose ultrabasic rock or ilmenite in basic rock, without Nb and Ta, to reduce the interference of substances on the reaction.

[0027] Ilmenite is processed according to actual needs to form thin strips or flat structures. The thin strips of ilmenite are ground by a grinder, and the preferred thin strips of ilmenite have a circular cross-section, while the flat structure of ilmenite is obtained by grinding Stamped, ilmenite has a larger surface area per unit volume after processing, which facilitates subsequent reactions.

[0028] Step B: Pour sulfuric acid into the container, and continue to intro...

Abstract

A preparation method of photocatalyst activated carbon comprises the following steps: step A, processing ilmenite to form a thin strip-shaped or flat structure, and placing the processed ilmenite in a container; step B, pouring sulfuric acid into the container, continuously introducing air into the container, and continuously stirring the processed ilmenite; step C, putting water and activated carbon into the container while stirring to obtain TiO2 and H2SO4 under the condition that whole activated carbon is soaked in solution in step B; step D, taking out the activated carbon, uniformly sticking broken glass on the surface of the activated carbon when the solution on the surface of the activated carbon is in a semi-dry state, and uniformly arranging the broken glass in a spraying or rolling bonding manner; and E, adhering the glass powder solution to the outer side of the broken glass slag, and uniformly arranging the glass powder solution in a sprinkling or rolling adhesion manner in the same way.

Description

technical field [0001] The invention relates to the technical field of photocatalyst activated carbon, in particular to a preparation method of photocatalyst activated carbon. Background technique [0002] Photocatalyst is a compound word of light + catalyst (catalyst), and photocatalyst is a general term for photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide. It is currently the most ideal material for indoor environmental pollution control in the world. [0003] Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxyl groups and active oxygen with strong oxidation ability, have a strong photoredox function, and can oxidize and decompose various organic compounds and parts Inorganic substances can destroy bacterial cell membranes and solidify virus proteins, kill bacteria and decompose organic pollutants, and decompose organic pollutants into n...
