TSU creates a catalyst to protect the atmosphere from emissions

A group of scientists at the TSU Laboratory of Catalytic Research (LCR) has created a new multifunctional material that combines the properties of a sorbent and a catalyst and will help solve environmental problems. The new catalyst is capable of capturing and neutralizing toluene, benzene, methanol, and other hazardous substances from industrial discharges and exhaust gases from vehicles. The scientists presented the fundamentals of creating catalysts for improving the environment in a review article published by one of the most prestigious world journals in catalysis, Applied Catalysis B: Environmental (Q1).

- In this article, we carry out a systematic analysis of the latest research in the creation and application of Pt-CeO2 composites, - says Mikhail Salaev, senior researcher at LCR. - The complementary properties of platinum and cerium oxide particles make it possible to use these materials in environmental catalysis, for example, in the neutralization reactions of a wide range of volatile organic compounds, soot, nitroaromatics, and for the utilization of carbon dioxide and photocatalytic processes. The article talks about modern methods of designing such materials, the influence of these methods on the properties of platinum particles, the surface of cerium oxide, and the nature and structure of active centers.
