AI Technical Summary
Existing photocatalytic glass can only produce a catalytic reaction under ultraviolet light or strong sunlight, resulting in extremely low purification efficiency indoors or in low light environments, and it becomes completely ineffective at night, failing to meet the need for continuous 24-hour purification.
A visible light catalytic layer composed of nano-silver and nano-titanium dioxide decomposes formaldehyde under light irradiation. A chemical adsorption catalytic layer composed of nano-manganese dioxide powder and activated carbon particles adsorbs and decomposes formaldehyde in the absence of light. Light energy is absorbed and transferred to the visible light catalytic layer through a nano-nitrogen-doped titanium dioxide light energy conversion layer. Combined with a hydrophobic silica sol anti-reflective and antifouling layer and an ion exchange barrier layer, efficiency and lifespan are improved.
It achieves continuous formaldehyde purification under both light and dark conditions, overcoming the defect of traditional photocatalytic glass failing at night, extending the service life of the catalyst layer and improving purification efficiency.
