CNT-interconnected iron-doped NiP2/Ni2P heterostructural nanoflowers as high-efficiency electrocatalyst for oxygen evolution reaction

Metal–Organic Framework-Derived Fe-Doped Ni3Se4/NiSe2 Heterostructure-Embedded Mesoporous Tubes for Boosting Oxygen Evolution Reaction

“…Besides that, the Ni-MOF-Se-400 showed a better C dl value than the NiFe 0.2 -MOF-Se-400, possibly owing to its nanosheet morphology that can contribute to the enhanced surface area. 26,63,64 Additionally, the high OER activity of Ni-MOF-Fe-Se-400 was verified by the lowest charge-transfer resistance (R ct ) detected in its EIS (Figures 5e and S10). A smaller R ct signifies that the interactions at the electrode−electrolyte interface are quite feasible, which can enhance the OER activity.…”

Electronic structure modification and N-doped carbon shell nanoarchitectonics of Ni3FeN@NC for overall water splitting performance evaluation

“…The way to adjust the band gap is by doping a transition metal and a carbon material with various kinds of elements (N, P, S, O, or Se). [19][20][21][22] However, it has not been proven to satisfy all conditions for use as a catalyst material. Therefore, further research needs to be conducted on synthetic methods, such as doping, coating, and hybridization, which have been employed in previous studies, and to improve the performance by chemical and physical methods based on previous research.…”

Coupling of PET waste electroreforming with green hydrogen generation using bifunctional catalyst

“…30,31 Furthermore, other two peaks centered at 852.9 eV and 869.8 eV are consistent with Ni-P bonds. [32][33][34] On the Co 2p XPS spectrum, the two peaks located at 778.6 eV and 793.7 eV correspond to Co 2p 3/2 and Co 2p 1/2 of Co-P, respectively. And the two peaks located at 782.0 eV and 798.2 eV are consistent with Co-O bond, with two satellites detected at 803.4 eV and 786.0 eV (Fig.…”
