Abstract

The invention discloses a wide waveband photocatalyst air cleaner, which comprises a container, wherein compound photocatalyst particles are arranged in the container. The container is prepared by sintering anion power, dolomite and pore-forming agent. The compound photocatalyst particles are prepared by sintering the anion power, tourmaline, maifanitum, nanometer titanium dioxide, cerous oxide and viscous pottery clay. The invention has the following great advantages: 1, the production rate of anions is high; and 2, no additional power supply is needed, and natural light can penetrate through a container wall and an air hole on the container wall to exchange with the surfaces of the compound photocatalyst particles so as to realize the purpose of purifying air, thereby bringing greatly convenience for use. The air cleaner in the invention can be arranged on desks, bedside tables and windows as well as in automobile and the like. The container can be made into various ornaments, such as egg-shaped, vase-shaped, animal-shaped, cartoon-shaped ornaments and the like, and has beautiful appearance and practical use.

Description

technical field [0001] The invention belongs to the field of daily necessities, and specifically refers to a photocatalyst air purifier which can be placed indoors or in a car to remove toxic and harmful gases in the air and improve the wide-band response (ultraviolet-infrared band response) of the internal ambient air. Background technique [0002] Photocatalyst, also called photocatalyst, is a kind of titanium dioxide (TiO 2 ) is a general term for semiconductor materials with catalytic functions, which do not change themselves under the irradiation of light, but can promote chemical reactions. TiO 2 As a photocatalyst, after absorbing ultraviolet rays from sunlight or lighting sources, oxidation-reduction reactions occur under the excitation of ultraviolet energy, and strong oxidative hydroxyl radicals and superoxide anion radicals are formed on the surface to remove harmful substances in the air. Substances and microorganisms are decomposed into harmless carbon dioxide...
