Modern society heavily relies on transportation. The internal combustion engines that power most vehicles emit gaseous pollutants that are harmful to human health and to the environment. Catalytic removal of toxic carbon monoxide (CO) from exhaust fumes is typically done with expensive noble metals as one of the key components of automotive catalytic convertors. For his PhD research, Valerii Muravev explored ways to improve the efficiency of costly catalysts by optimising the use of noble metals in convertors. Muravev recevied his PhD cum laude on November 26th 2021.
