Problems solved by technology

[0002] The home environment pollution caused by pollutants in interior decoration and building materials has attracted people's attention. There are many kinds of volatile organic compounds in the indoor air, including many carcinogens and pathogenic viruses, and the unknown components are also quite complex. The most representative one is formaldehyde, which greatly increases the risk of cancer. Therefore, various purifiers have emerged. In the prior art, many air purifiers use photocatalysts to kill viruses and bacteria, and decompose formaldehyde and other toxic gases. TiO 2 The oxide-type photocatalyst represented by bismuth titanate has excellent catalytic performance and stable chemical performance, but its band gap is wide and only absorbs ultraviolet light. The ternary bismuth oxide semiconductor represented by bismuth titanate, as a kind of Photocatalysts with visible light catalytic activity have attracted much attention, but pure Bi 4 Ti 3 o 12 The absorption efficiency of visible light is not high, and the electron-hole recombination rate is high, so its photocatalytic efficiency is low; in addition, lamps are commonly used indoor lighting devices, and their functions are relatively single
