Embodiment Construction

[0028] use Figure 1-Figure 4 The preparation process of a photocatalyst according to an embodiment of the present invention is described as follows.

[0029] like Figure 1-Figure 4 Shown, the preparation technology of a kind of photocatalyst of the present invention, this technology comprises the following steps:

[0030] S1: Put metal titanium into a glass beaker, add aqueous hydrogen peroxide solution to form a mixed solution, the molar ratio of metal titanium to hydrogen peroxide is 1:7; the metal titanium is granular sponge titanium; then place the glass beaker on ice In the water bath, the temperature of the ice-water bath is controlled at 20°C, and the mixed solution is stirred at a medium speed to form an intermediate reactant;

[0031] S2: Pour a certain amount of ammonia water into a flask with a branch pipe and a piston, place the flask in a hot water bath, control the temperature of the water bath at about 60°C, and heat to volatilize ammonia to form ammonia vapor...

Abstract

The invention belongs to the technical field of photocatalytic purification, and particularly relates to a preparation process of a photocatalyst. A catalyst film comprises a bottom film and a wrapping sheet; the bottom film is in a circular truncated cone shape, the thickness of the bottom film is not larger than 1 cm, and wrapping pieces are evenly and fixedly connected to the side wall of the bottom film. The top view of the wrapping piece is triangular, and the wrapping pieces can be folded inwards to form a sealing body with the bottom film. The sealing body is arranged to be conical; andthe upper surfaces of the wrapping pieces are fixedly connected with a blocking piece. The preparation process is mainly used for solving the problems that in the prior art, when a photocatalyst is prepared into a thin film, the natural cooling process is long, so that the preparation process time is long; and copper powder is added during preparation, so that the heat-conducting property of thethin film is enhanced, the natural cooling time of the thin film is shortened, and the preparation efficiency of the thin film is further improved.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic purification, in particular to a preparation process of photocatalyst. Background technique [0002] Photocatalyst, namely photocatalyst, is a general term for a photo-semiconductor material with photocatalytic function represented by nano-scale titanium dioxide. It is coated on the surface of the substrate and produces a strong catalytic degradation function under the action of ultraviolet light and visible light: Effectively degrade toxic and harmful gases in the air; and can effectively kill a variety of bacteria in the water, and can decompose and harmlessly treat the toxins released by bacteria or fungi; it also has formaldehyde removal, deodorization, anti-pollution, purification functions such as air; [0003] Among them, titanium dioxide photocatalytic technology is an advanced oxidation decomposition technology. The surface of titanium dioxide particles generates charge separation...
