Embodiment Construction

[0013] The following examples further specifically illustrate the technical solution of the present invention.

[0014] In this embodiment, the carrier of the catalyst adopts ultrafine or nanometer activated carbon, and the active component is composed of 2-20% manganese dioxide and 2-15% copper oxide as the main catalyst, and 0.01-0.02% palladium oxide as the secondary catalyst.

[0015] The preparation method adopts dipping to roasting method, that is, manganese nitrate and copper or palladium nitrate is dissolved in deionized water, immersed in ultrafine or nano activated carbon and dried at 100℃~120℃, and then at 350℃~450℃ It is calcined for 2 to 4 hours and cooled to become a supported nano-scale catalyst.

[0016] For example, take 188g of manganese nitrate, 293g of copper nitrate, 0.04g of palladium nitrate, 700ml of deionized water, dissolve these nitrates in deionized water, and immerse 1kg of ultrafine activated carbon powder in deionized water mixed with nitrates for 1.5 h...

Abstract

The invention relates to a reduction catalyst technology, in particular to a load type ozone nanometer type reduction catalyst and a manufacturing method thereof. The invention is characterized in that each kilogram of superfine or nano activated carbon is added with 27g-725g of manganous nitrate, 73g-590g of copper nitrate, 0.019g-0.093g of palladium nitrate and 650g-850g of deionized water, andthe mixture is dipped for 0.5 to 1 hour, dried in a constant temperature drying device, then roasted for certain time at set temperature and manufactured into the load type nano catalyst after being cooled.

Description

Technical field [0001] The invention relates to a reduction catalyst technology, in particular to a supported ozone nano-type reduction catalyst and a manufacturing method thereof. Background technique [0002] Ozone is widely used in sterilization, deodorization, wastewater treatment and other fields. The unused ozone directly enters the atmosphere without being treated, which poses a certain threat to human health. Ozone can also be produced in modern electrical appliances. For example, the ozone produced by corona discharge and high-voltage discharge in engine room, copier, printing machine, fax machine, disinfection machine, etc. will also directly affect the ambient air and seriously affect our health. At present, there are many types of reduction catalyst preparation methods on the market, each with its own performance characteristics. [0003] If the patent number is ZL01105215.5, a loaded ozone (O 3 ) Reduction catalyst and its manufacturing method, characterized by adding...
