New Insights Into Exsolution Catalyst Fabrication Published

Journal of the American Chemical Society Features RWTH Research on Catalyst Innovation

Catalysts made from solid materials are used to produce approximately 90 percent of industrially important chemicals. A key type of such catalysts consists of nano-sized metal particles finely dispersed on an oxide support. The fabrication of such catalysts faces several critical challenges: the metal particles should neither be too large nor too close to each other, and they should maintain their dispersion even under extreme operating conditions to ensure that the often-expensive metals are used as efficiently as possible.

Recently, there has been significant interest in ’exsolution’ as a straightforward way to address these challenges. ...
