Abstract

The invention relates to the technical field of formaldehyde-removing jelly, in particular to high-visible-light-activity TiO2 / Ag formaldehyde-removing jelly and a preparation method thereof.The high-visible-light-activity TiO2 / Ag formaldehyde-removing jelly is prepared from, by mass, 5%-80% of TiO2 / Ag active components, 3%-30% of gelatinizing agents, 2%-6% of chlorite, 0.05%-3% of preservatives and the balance water, and the total mass percentage is 100%. The TiO2 / Ag formaldehyde-removing jelly is simple in ingredient, can efficiently degrade formaldehyde under visible light, does not need extra ultraviolet light source equipment compared with ultraviolet light degradation of formaldehyde, and is more environment-friendly, safer and free of toxic and side effects. In addition, sodium chlorite generates chlorine dioxide gas under an acidic condition, TiO2 / Ag can quickly catalyze and oxidize formaldehyde in air during illumination, and TiO2 / Ag can control the release speed of chlorine dioxide through a cage effect, so that a long-acting catalytic degradation effect is achieved, and an air purification guarantee can be provided for an indoor environment.
