Solid-state catalysts mediate a large fraction of commercial chemical reactions. Typically, these chemistry workhorses lose some of their ability to transform reactants to products as a result of various aging processes. One such process converts active metallic catalyst sites to inactive metal oxides. That undesirable change requires frequent chemical reactor maintenance, which is costly. A team led by Jason Hattrick-Simpers and Jochen Lauter­bach of the University of South Carolina, . . .
