Abstract

The invention relates to an ozone elimination catalyst with a porous substrate as the carrier. The ozone elimination catalyst is prepared by loading a coating solution on the porous substrate. The coating solution comprises the following active ingredients by weight: 0.8-1.2 parts of stearic acid sorbitol ester, 1.6-2.4 parts of OP-10, 4.2-5.8 part of polyethylene glycol, 0.15-0.85 part of carboxymethyl cellulose sodium, 1.1-1.9 parts of polyvinyl alcohol, 3.2-4.8 parts of vinyl acetate, 90-110 parts of water, and 2-50 parts of a nano-metal oxide. The invention also provides a preparation method of the ozone elimination catalyst with the porous substrate as the carrier. The prepared catalyst has the advantages of long service life, low cost, small wind resistance, and no secondary dust.

Description

technical field [0001] The invention belongs to the technical field of air purification materials, and relates to an ozone elimination catalyst, in particular to an ozone elimination catalyst with a long life, low cost, small wind resistance and no secondary dust pollution, and a porous substrate as a carrier and a preparation method thereof. Background technique [0002] Ozone is a strong oxidant that exists in many occasions, such as ozone air disinfection machines, ultraviolet lamps, fruit and vegetable disinfection machines, negative ion generators, electrostatic precipitators, copiers, etc. Although ozone is an excellent disinfectant, due to its high toxicity, its maximum concentration is limited to 0.10mg / m in various environments 3 . Therefore, it needs to be eliminated. [0003] The ozone elimination catalyst composed of Pt, Pd, Ag, Ce and other rare metals has high efficiency and long life, but its disadvantage is that it is expensive, which greatly limits the sco...
