Abstract

The invention relates to a flexible platinum formaldehyde room-temperature oxidation catalyst and a preparation method thereof, in particular to a Pt / TiO2 / cotton fiber flexible composite formaldehyde room-temperature oxidation catalyst and a preparation method thereof. The catalyst comprises a degreased cotton fiber carrier, a nano TiO2 surface coating and Pt active ingredients dispersed on the surface of the TiO2 coating, wherein the Pt active ingredients exist in a zero-valence form, grain size ranges from 1nm to 10nm, and loading capacity is 0.05-2wt%. The Pt / TiO2 / cotton fiber flexible composite formaldehyde room-temperature oxidation catalyst has the advantages of hierarchical mesoporous-macroporous structure, light weight and flexibility, Pt is combined firmly with the TiO2 coating and carrier cotton fiber, elemental Pt of the active ingredients is high in dispersity on the surface of the TiO2 coating and small in grain size and can catalytically decompose formaldehyde efficiently at room temperature, noble metal Pt is low in consumption and air resistance, and the catalyst is suitable for using used in various air purifiers.

Description

technical field

[0001] The present invention relates to a kind of Pt / TiO 2 The invention discloses a catalyst for room-temperature oxidation of cotton fiber composite formaldehyde, which belongs to the field of indoor air purification. Background technique

[0002] Formaldehyde is one of the most important pollutants in indoor air and has great toxicity. At present, eliminating indoor formaldehyde pollution has become a hot research topic in the field of environmental governance. Among the existing formaldehyde removal methods, the room temperature catalytic oxidation method is better than other methods (adsorption method, absorption method, negative ion oxidation method, ozone catalytic oxidation method, biological filtration / plant purification method, low temperature plasma method and photocatalytic oxidation method, etc.) It has unique advantages, it can be carried out under normal temperature and pressure, high formaldehyde removal efficiency, simple equipment, long li...
