IMASC 2.0 is building on significant progress. IMASC 1.0 established a new paradigm, resulting in fundamental understanding of model surfaces at the molecular scale to predict catalytic performance for support-free dilute alloy materials. Our highly collaborative center-wide research demonstrated that dilute alloy catalysts are capable of highly selective catalysis, predicted in part by the disparate reactivity of the minority and majority metals. Notably, dynamic restructuring of the alloy during activation and under catalytic conditions was used to create and sustain the active sites necessary for robust catalysis, thus providing a means of controlling selectivity.
