How to remove ozone from the air?

Ozone, I believe everyone is familiar with it. It has strong oxidizing properties, so it is often used in medical and other industries for disinfection and sterilization, but it actually has a dual identity. In the high altitude, the ozone layer can protect us, and once it sneaks into the ground, it will endanger human health. In particular, ozone released in industrial production and waste gas and wastewater treatment will damage the human respiratory system and pollute the environment.
In what scenarios does ozone generally exist?
Waste gas emitted by factories and the printing industry are spaces where a large amount of ozone is retained; in fact, it also exists in office places. For example, laser printers will produce ozone when they are running, and the residual ozone gas after disinfection will also cause harm to the human body if it is not treated in time; the tap water that people drink daily also needs to be disinfected. For example, if the water plant uses ozone for disinfection, there will be residual ozone gas emitted to cause harm, etc.
These thorny problems must always be dealt with, otherwise ozone will become a "cruel executioner" that harms humans. There are actually many ways to remove ozone. Such as activated carbon adsorption, thermal decomposition, photocatalysis, catalytic decomposition, etc. Here we focus on the catalytic decomposition method of ozone decomposition catalyst. 
The ozone decomposition catalyst can mainly catalyze the conversion of harmful ozone into harmless oxygen, and in this process, ozone does not need to participate in the reaction, so it can be used for a long time, which can be said to be a huge cost saver! Ozone decomposition catalysts can effectively reduce the activation energy of ozone decomposition. Ozone decomposition catalysts composed of transition metal oxides such as copper oxide and manganese dioxide have active sites on their surfaces, which can adsorb ozone molecules and recombine them into oxygen molecules. No other energy consumption will be generated in this reaction. For example, in the production process of chemical and pharmaceutical products, tail gas destructors have become key equipment for end-of-pipe treatment. Its core component is the ozone decomposition catalyst layer - when the waste gas containing high concentrations of ozone passes through the catalyst layer, the ozone molecules are quickly decomposed into oxygen on the catalyst surface.
With the development of industry and the improvement of environmental standards, the scientific research team will develop more efficient, energy-saving and broad-spectrum ozone decomposition catalysts to create a cleaner air environment for mankind.
