Single-atom catalysis: A practically viable technology?

Recent advances in single-atom catalysis resulted in readily accessible materials whose application in most catalytic reactions mediated by conventional nanoparticle-based catalysts often results in higher activity and selectivity. Can we expect catalysis by atomically dispersed atoms to find practical applications? Which are the hurdles to be overcome before widespread uptake of atomically dispersed metals in industrial synthetic processes and in hydrogen fuel cells? © 2020 Elsevier B.V.
