A breakthrough in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to the development of clean diesel engine technology and help combat air pollution.
Catalysis is an important process that underpins the chemical industry allowing us to efficiently produce the chemicals that we need. It also allows us to clean-up the pollution that we would otherwise emit into the atmosphere. Catalysts are typically metallic nanoparticles, often platinum group metals that are finely deposited upon a substrate. The activity and durability of the catalyst critically depend upon the interaction of the particles with the substrate.
In recent years the team at the University of St Andrews have been exploring metal nanoparticles prepared by exsolution at the surface of perovskite oxides and have shown these structures to enable new dimensions in catalysis and energy conversion and storage technologies owing to their socketed, well-anchored structure.
The findings are published in the journal Nature Communications.
