Highly stable silver nanohybrid electrocatalysts for the oxygen reduction reaction

Silver nanoparticles (AgNPs) were deliberately functionalized via 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. Deli...

Zusammenfassung:Silver nanoparticles (AgNPs) were deliberately functionalized via 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. Deliberate functionalization of silver nanoparticles with a monolayer of calix[4]arenes leads to a highly stable electrocatalyst toward the ORR.
