Abstract

A nano-class coated membrane for cleaning air and generating negative ions carries the TiO2 nanoparticles for generating electrons and holes in photocatalytic condition to trigger redox reaction which can decompose the harmful gas (formaldehyde) into CO2 and H2O and the polar ore nanoparticles for generating electric current under thermal excitation of pressure and temp to electrolyze the H2O and release negative ions.

Description

[0001] Technical field: The present invention relates to a preparation technology formula of "nano-air-purifying anion coating film". It belongs to nano / micro composite environmental protection functional new material. technical background: [0002] 1. Nano-TiO 2 Photocatalysis research has become a hotspot, but in terms of air purification and treatment, they all follow the single purification function of Japan's "photocatalyst". Although negative ion generators have been launched on the market, they consume electric energy and have limited efficacy. Evaluation of indoor air: Clean air without negative ions is like a lack of nutrition in the human body; high negative ions in polluted air are also meaningless. Only clean air + high concentration of negative ions is the most beneficial to the human body. This study starts with dual functions and high efficiency, and exerts the synergistic effect of the two materials of air purification and induction of negative ions. Integra...
