Abstract
Photocatalytic technology has become a hot technology for environmental pollution control due to its advantages of good stability, high degradation efficiency and no secondary pollution. The application of tin oxide nano materials in environmental photocatalysis is proposed. Acetaldehyde gas was selected to simulate the pollutant, and tin oxide nano materials were used to degrade acetaldehyde concentration in a photocatalytic reactor. The experimental results show that the degradation rate of 95% pure tin oxide nanomaterials in environmental photocatalysis is 88.82%, which indicates that the photocatalytic degradation performance of tin oxide nanomaterials is better.
