Specialists from NSU have presented a new catalyst that can purify the air from carbon monoxide, one of the most common pollutants. The development was carried out as part of a collaboration between the Institute of Catalysis of the SB RAS.
The catalyst operates at room temperature and can be activated not only by ultraviolet light, like traditional photocatalysts, but also by natural light and ordinary light sources. This is why the device is particularly convenient for use in residential and office premises.
The basic principle of the catalyst is based on photocatalytic oxidation, a process in which pollutants decompose under the influence of light. The device prevents the formation of carbon monoxide as a byproduct and is capable of destroying chemical compounds, including viruses and bacteria.
The development can be used in air purification systems and as a photoactive coating for walls and other surfaces. Scientists emphasize that their goal is to protect the environment and human health, as carbon monoxide can negatively affect health by blocking the transport of oxygen in the blood.
To increase the efficiency of the catalyst, scientists modified it by applying nanoparticles of noble metals, such as platinum and palladium, to the surface. The particles promote faster oxidation of carbon monoxide, which makes the purification process more efficient.
There is already interest from major manufacturers in the Russian market who want to use the new catalyst to improve their products. NSU scientists are also working on creating self-cleaning coatings that will provide constant purification of premises from carbon monoxide.
