Abstract

The invention discloses a preparation method of a photocatalytic complexing agent with high light conductivity and high adsorption performance for purifying air. The preparation method comprises the following steps: (1) synthesizing a composite adsorption carrier; (2) synthesizing a Pd / TiO2 composite colloidal solution, wherein the content of Pd in the Pd / TiO2 composite colloidal solution is controlled to be 0.001-0.1 wt%; and (3) immersing the composite adsorption carrier prepared in the step (1) into the Pd / TiO2 composite colloidal solution prepared in the step (2) for 10-120 minutes, takingout the composite adsorption carrier, and drying the composite adsorption carrier at 25-100 DEG C to obtain the photocatalytic complexing agent with high light conductivity and high adsorption performance for purifying air. The photocatalytic complexing agent with high light conductivity and high adsorption performance for purifying air has high purification efficiency, good water resistance andhigh adsorption performance.

Description

technical field [0001] The invention relates to the technical field of air purification materials, in particular to a preparation method of a photocatalytic composite agent for purifying air with high light conductivity and high adsorption performance. Background technique [0002] At present, there are various products for air purification such as activated carbon, photocatalyst (photocatalysis), aldehyde remover and other products on the market, but there are relatively few photocatalytic activated carbon particles or photocatalytic composite porous adsorption products, and some photocatalytic composite products are also prepared. Mainly use titanium-based liquid or titanium dioxide sol liquid as the precursor liquid to undergo soaking, drying, high-temperature treatment and other processes. Some photocatalytic air purification effects are not very ideal. The photocatalytic loading methods mainly include powder sintering method, dipping and pulling method, Sol-gel method, ...
