AI Technical Summary
Existing air purification materials struggle to maintain stable formaldehyde removal and purification effects under common lighting conditions, and also suffer from issues with transparency, weather resistance, and long-term reliability.
A composite membrane structure consisting of nitrogen-doped titanium dioxide particles supported on aminated mesoporous silica is adopted, including a bottom anchoring layer and an outer purification layer. The supported purification particles are mainly distributed on the outer purification layer, forming an interlayer transition region between the two layers. The photocatalytic effect is enhanced by the synergistic effect of the amino adsorption sites and the nitrogen-doped titanium dioxide photocatalytic sites.
It maintains a stable purification effect under common lighting conditions, improves the transparency and adhesion stability of the composite membrane, extends its service life, and enhances its ability to decompose formaldehyde, benzene, and odor molecules.
