Surface Science of Catalytic Oxidation, Epoxidation and Automotive Emissions
This community investigates the atomic and molecular mechanisms of chemical reactions on solid surfaces, focusing on catalytic oxidation, the selective epoxidation of alkenes, and the reduction of automotive exhaust emissions.
The work centers on the interaction of gases such as oxygen, carbon monoxide, and hydrocarbons with metal and oxide surfaces. Recurring subjects include three-way catalytic converters for gasoline and diesel engines, silver catalysts for ethylene and propylene epoxidation, and the use of atom probe tomography to map atomic structures. Researchers examine adsorption, surface reactions, and the stability of active sites on materials like platinum, nickel, and alumina. The goal is to understand how surface composition and structure dictate reaction rates and selectivity in industrial and environmental applications.
The community is most heavily concentrated in platinum research, representing 2.0% of all tracked platinum papers, with 2,904 papers in this group. It also accounts for 1.2% of tungsten research (1,434 papers) and 1.0% of aluminium research (1,580 papers).
The community comprises 28,684 papers, published primarily in Surface Science, the Journal of Catalysis, and The Journal of Chemical Physics.
Recent work continues to focus on the atomic mechanisms of ethylene epoxidation on silver surfaces and the performance of three-way catalysts for heavy-duty natural gas engines.
