Two research teams have developed a novel theoretical model to describe the overall activity of multisite alloy catalysts. In their study published in Journal of the American Chemical Society, they propose a concept of equivalent site ratio and successfully quantified the contributions of various active sites in Pt-Ru disordered solid solution (DSS) alloys.
