Nanometer semiconductor photocatalysis device for air purification

Abstract

The invention firstly provides a nano semiconductor photocatalysis device for air purification, and aims to solve the problems that a traditional photocatalysis device is difficult in catalytic environment condition control and large in size and is difficult to meet market use. The nano semiconductor photocatalysis device comprises a plurality of membrane-shaped porous metal plates, which are assembled to form an area where the porous metal plates are concentrated, wherein each porous metal plate is provided with three-dimensional communicated pores, the pores are configured to deposit metatitanic acid through a chemical precipitation method, and a titanium dioxide particle layer attached to the surfaces of the porous metal plates is formed through calcination. According to the scheme, the air purification function is achieved through the photocatalytic property of the nanometer semiconductor, the air purification effect is achieved through air exchange and condensate water mist in the cold and hot area exchange process in the purification process, a convection fan does not need to be adopted for driving in the purification process, rich hydroxyl groups can be formed through condensate water, and the device can directly adopt a UV light source for catalysis.
