The oxidation energy of hydroxide radicals generated by photocatalyst under light is about 140 kcal/mol, and the oxidation energy of highly reactive oxygen ions is as high as 120 kcal/mol, which is much larger than the bonding energy between atoms inside the molecules of organic substances or other substances, so it can oxidize and decompose formaldehyde, dumb substances, TVOC, ammonia and nitrogen, hydrogen sulfide, cyanide, substate ions, unstable compounds and other substances that can be oxidized and decomposed. The end product is the full combustion of the substance in pure oxygen. Photocatalyst series product is one of our main products, it have good appearance, structural strength and industry priority in exhaust gas treatment performance. We choose high-quality nano-grade titanium dioxide as the basic material, through a unique formula modulation, to achieve industry-leading product performance. Through the strict control of the formula and carrier, we realize the efficient photo-oxidation catalytic effect which greatly improves the efficiency of formaldehyde and tvocs gas treatment, and it can adapt to various working conditions.
