Can Lanshe 1 decompose formaldehyde?

Diatom mud itself has only adsorption performance and no decomposition function. After a period of time, because the adsorbed substances are relatively saturated, the adsorption effect will be greatly reduced, and even saturated reflux will occur. Lanshe 1 is added to some diatom mud, and its main component is nanometer titanium dioxide, which will continuously decompose harmful substances in indoor air under the comprehensive action of added photocatalyst.
