WebThe analysis of the ORR reaction pathway shows that Fe-TCPP and Fe-(mIM)4 have good catalytic activity. Following, the confinement effect (5~14 Å) was introduced to investigate its influence on the catalytic activity. The Fe-TCPP and Fe-(mIM)4 active sites have the lowest overpotential at the axial space of 8Å and 9Å, respectively. WebThe curved edge, nitrogen and carbon co-doped trimetallic-organic framework-derived phosphide grown on nickel foam (Ni–Fe–Mn–P/NC@NF) demonstrates low …
WebThe curved edge, nitrogen and carbon co-doped trimetallic-organic framework-derived phosphide grown on nickel foam (Ni–Fe–Mn–P/NC@NF) demonstrates low overpotentials of 72 mV at 10 mA cm −2 for the hydrogen evolution reaction (HER) and 274 mV at 30 mA cm −2 for the oxygen evolution reaction (OER), with corresponding Tafel slopes of ... 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 potential …
