Highly stable silver nanohybrid electrocatalysts for the oxygen reduction reaction

Abstract

Silver nanoparticles (AgNPs) were deliberately functionalized <i>via</i> aryl diazonium chemistry with a monolayer of calix[4]arenes. The resulting nanohybrids show high efficiency and high selectivity toward the ORR in alkaline media along with an exceptional durability and a high methanol tolerance.
