“…3c), two distinct peaks at approximately 128.9 eV and 129.7 eV were observed, attributed to the presence of reduced phosphorus within the metal phosphides. 40,41 A noteworthy observation was the positive shift of approximately 0.3 eV in the binding energy for the Ni 2p 3/2 spectrum of A-NiFeP/NiP-Fe:10% and A-NiFeP/NiP-Fe:25%, in comparison to that of NiP (Fig. 3a).…”

“…[10] The strong electron interaction can accelerate charge transfer, improve electron conductivity, regulate electronic structure on the interface and optimize the adsorption energies of reaction intermediates, which is in favor of the dissociation of water and the adsorption and desorption of hydrogen, thus enhancing catalytic performance. [9][10]25] Mean- while, the P 2p region was fitted to three peaks, corresponding to P 2p 1/2 (130.5 eV) and P 2p 3/2 (129.5 eV) for PÀ Co or PÀ Fe as well as PÀ O bonds (134.4 eV) (Figure 2c). [26] In addition, the effect of phosphating treatment on phosphorus atom coordination was investigated using electron paramagnetic resonance (EPR).…”

“…1 However, as a renewable energy resource with high energy density, hydrogen may be able to effectively alleviate the above issues. 2,3 Capturing sunlight as a driving force for splitting water to produce hydrogen is considered an ideal and promising tactic. [4][5][6] Photocatalytic hydrogen evolution has also faced impediments, such as low charge transfer efficiency, low activity, and poor light utilization.…”
