Abstract

Exsolution, nanoparticle precipitation from oxide materials during reduction, offers a promising approach to heterogeneous catalysis. Here, authors examine the switching behavior between high and low activity and correlate the electro-catalytic activity to exsolved phases from complex oxides.
