NOVELTY - Preparing monolithic ozone decomposition catalyst with adjustable shape comprises mixing manganese acetate, graphene oxide and solvent according to the dosage ratio of 9g: 1 g: 20 ml to obtain suspension A, (ii) mixing potassium permanganate and solvent according to the dosage ratio of 4.5 g: 20 ml to obtain solution B, (iii) in the state of stirring, quickly dropping the solution B into the suspension A, and (iv) pouring the above mixed solution into a mold, freeze-drying and calcining. USE - The monolithic catalyst is used in unique volume and shape requirements of ozone tail gas treatment system, including disinfection cabinet, printer, air purifier, fresh air system, and ventilation fan (claimed). ADVANTAGE - The method uses manganese acetate, potassium permanganate, and graphene oxide as precursors, adopts a freeze-drying method, and realizes the shape control of the integral ozone decomposition catalyst by changing the shape of the mold, can customize the catalyst according to the requirements for the shape and size of the ozone decomposition module in specific application scenarios, and meets the special requirements for the shape and size of the ozone decomposition module for disinfection cabinets, printers, air purifiers, fresh air systems, and ventilation fans. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of catalyst in ozonolysis reactions with a humidity greater than 60%, and the time for the ozonolysis efficiency of more than 99% exceeds 5000 hours.
