The removal rate of the honeycomb ceramic net prepared through photocatalysis to formaldehyde and toluene in the air is 98.7% and 92.2% respectively, and the removal rate to formaldehyde and toluene in the air is improved by 2.0 times and 1.9 time respectively compared with the application of the TiO2 photocatalyst film only.
