15 Σεπ 2020 · In this work, we have demonstrated a facile method to fabricate NiFe LDH/NiTe composites for enhancing the OER performance by partial chemical etching of nickel foam to prepare NiTe nanoarrays, and subsequently depositing NiFe LDH with a hydrothermal process.
15 Σεπ 2020 · NiFe LDH/NiTe interface nanorod was built by forming NiFe LDH at the surface of NiTe nanorod. The binding strength of intermediates are optimized by electronic interaction of NiFe LDH and NiTe. The NiFe LDH/NiTe interface nanorods exhibit remarkable OER activity in 1.0 M KOH.
6 Φεβ 2023 · Nitrogen-doped graphitic carbon materials hosting single-atom iron (Fe–N–C) are major non-precious metal catalysts for the oxygen reduction reaction (ORR). The nitrogen-coordinated Fe sites are described as the first coordination sphere.
10 Μαΐ 2021 · We found that the spin polarization occurs at the first electron transfer step in OER, where coherent spin exchange happens between the ferromagnetic catalyst and the adsorbed oxygen species with...
15 Ιουλ 2019 · The P-O-Fe bond and the redox cycle between N-P-O-Fe-O and N-P-O-Fe-O 2 on atomically dispersed Fe-N-P-C complex catalyst prepared directly form woody biomass efficiently reduced adsorption strength of OH*, which leads to outstanding ORR activity.
28 Νοε 2016 · Here, we report ultrathin metal–organic frameworks (MOFs) as promising electrocatalysts for the OER in alkaline conditions. Our as-prepared ultrathin NiCo bimetal–organic framework nanosheets on...
