Exsolution trends and co-segregation aspects of self-grown catalyst nanoparticles in perovskites

Abstract

Exsolution of transition metals from perovskites provides an effective route to useful catalysts, but the underlying factors governing exsolution remain poorly understood. Here, the authors find trends in exsolution in layered perovskites, showing that co-segregation of B-site dopant and oxygen vacancies plays a central role.
