Metal oxide photocatalyst is a semi-conductive material. Coated on the substrate, it can undergo violent catalytic degradation under the exposure of UV light. It can effectively degrade harmful gases, eliminate bacteria, and neutralize toxic gases released by bacteria or fungi. It can also be used for removing formaldehyde, odor, contaminants, and generally purifying air. It is suitable for all kinds of air filters and odor removal systems such as air conditioning, air purifying, vehicle air conditioning, workshop air purifying, etc. Metal oxide photocatalysts are suitable for a wide range of application and have been well received by our customers.
