WebMechanistic mysteries of nickel catalysts unveiled. New mechanistic studies have uncovered the role of salts and additives in the formation of active species in nickel-catalysed reactions. These results address ‘a fundamental gap in knowledge’, according to Eva Hevia, an expert in organometallic chemistry at the University of Bern ... WebThe real active moiety of Fe–N–C single-atom catalysts (SACs) during the oxygen reduction reaction (ORR) depends on the applied potential. Here, we examine the ORR activity of various SAC active moieties (Fe–N4, Fe–(OH)N4, Fe–(O2)N4, and Fe–(OH2)N4) over a wide potential window ranging from −0.8 to 1.0 V (vs. SHE) using constant …
