Abstract

The invention relates to the field of catalytic materials and especially relates to titanium-based composite catalyst gauze capable of high-effectively degrading formaldehyde and a preparation methodthereof. The base body of the titanium-based composite catalyst gauze is titanium gauze, wherein TiO2 nanoarray grows on the surface of the titanium gauze. A manganese based catalytic component is supported on the surfaces of the titanium gauze and TiO2 nanoarray. The titanium-based composite catalyst gauze has a netlike structure and great mechanical performance, is better in adaptability, can bedirectly used for manufacturing a composite filter screen in an air purifier, allows non-photo catalytic degradation of formaldehyde, can achieve self-regeneration, is prolonged in one-time working period, and has great electric-conductivity and can be electrified for self-heating regeneration further. The composite catalyst gauze also can be integrated with a one-key regeneration function when being assembled into equipment.

Description

technical field

[0001] The invention relates to the field of catalytic materials, in particular to a titanium-based composite catalytic net for efficiently degrading formaldehyde and a preparation method thereof. Background technique

[0002] Indoor wood, boards, furniture and wall surface coatings basically contain formaldehyde, and it has been found through research that the release period of formaldehyde is usually three to fifteen years. Even after a long time of decoration, many appliances will continue to Release formaldehyde. The No. 153 Bulletin released by the World Health Organization in 2004 determined that formaldehyde is a carcinogenic and teratogenic substance. Formaldehyde is also a recognized source of allergies and is one of the risk factors for childhood leukemia. According to medical journals and related literature reports, the harm of indoor formaldehyde to human health can be summarized as stimulation, toxicity and carcinogenicity.
