Embodiment

[0026] Example: as attached figure 1 , 2 , 3, 4, 5 and attached Figure 6 Shown, a kind of visible light response type photocatalyst, comprises the following components by weight: 18-25 parts of nano-titanium dioxide, 6-9 parts of inductive modification agent silver diethyldithiocarbamate, binder acrylic acid 2-5 parts of resin and 82-85 parts of distilled water.

[0027] In this embodiment, the silver diethyldithiocarbamate is doped with transition metal ions and non-metal ions to modify the nano-titanium dioxide, so that the photocatalyst can achieve the effect of visible light response, It can be activated within the wavelength of visible light to meet the needs of daily indoor UV reduction.

[0028] On the other hand, the dithio structure in the silver diethyldithiocarbamate can make the silver ion more coordinated with the titanium dioxide structure. Compared with the common transition metal salts in the prior art, this The silver diethyldithiocarbamate in the embodim...

Abstract

The invention belongs to the technical field of a photocatalyst, and especially relates to a visible light response type photocatalyst, a preparation method thereof and production equipment thereof. Through unique material proportioning, the preparation method and a high-efficiency stirring barrel device, the effect of effective preparation of the visible light response type photocatalyst can be achieved. The photocatalyst preparation method is reasonable and effective, the prepared photocatalyst has good air treatment effect under visible light, the stirring barrel device has good light-shielding stirring effect, and feeding and discharging are convenient during a mixing process.

Description

technical field [0001] The invention belongs to the technical field of photocatalysts, and in particular relates to a visible light responsive photocatalyst, a preparation method and production equipment thereof. Background technique [0002] Titanium dioxide photocatalyst, the valence band electrons are excited to the conduction band under light irradiation, directly forming electrons and holes, and finally forming superoxide anion radicals and hydroxyl radicals that can decompose organic pollutants and kill bacteria and viruses. On the other hand, pure nano-titanium dioxide powder can only be stimulated and effective when receiving ultraviolet light, and the content of ultraviolet light itself is reduced. Therefore, in real life, nano-titanium dioxide-based products are generally used for photocatalyst air treatment to achieve the effect of visible light response, that is, visible light It can make the titanium dioxide photocatalyst effective, but the existing titanium dio...
