Catalyst for non-photocatalytic degradation of VOC (Volatile Organic Compounds) as well as preparation process and preparation device

Abstract

The invention relates to the technical field of cleaning, in particular to a catalyst for non-photocatalytic degradation of VOC (volatile organic compounds) as well as a preparation process and a preparation device. The catalyst is C-M1Ox-M2Oy-M3NPs, x and y respectively represent the mass percentage contents of M1Ox and M2Oy in the catalyst, and the values of x and y are different along with the base material of the catalyst and are 50% lt; x + y < lt >; 60%; wherein M < 1 > O < x > is a first promoter, M < 2 > O < y > is a second promoter, C represents a catalyst TiO2, and M < 3 > N < Ps > is metal nanoparticles. And the M3NPs is Ag nano particles. According to the catalyst for catalytically degrading the VOC, the preparation process and the preparation device, the VOC can be degraded under the dark condition, and an excellent degradation effect can be achieved in a room or in a dark environment.

Description

technical field [0001] The invention belongs to the field of cleaning technology, and in particular relates to a catalyst for non-photocatalytic degradation of VOC, a preparation process and a preparation device. Background technique [0002] As people's requirements for the living environment are getting higher and higher, indoor environmental pollution has become a pain point in the hearts of ordinary people. Modern urbanites spend more than 80% of their time indoors. Volatile organic compound (VOC) pollution represented by formaldehyde and benzene series and microbial pollution represented by bacteria seriously endanger people's health. At present, the photocatalysts on the market can only effectively degrade formaldehyde under the action of short-wavelength strong light, and it is difficult to exert the degradation effect indoors or in a dark environment. [0003] Akira Fujishima, the father of photocatalysis in Japan, pointed out that if you want to use photocatalyst i...
