Self‐Supporting Ni‐M (M = Mo, Ge, Sn) Alloy Nanosheets via Topotactic Transformation of Oxometallate Intercalated Layered Nickel Hydroxide Salts: Synthesis and Application for Electrocatalytic Hydrogen Evolution Reaction

“…As shown in Figure S7 of the Supporting Information, the clear emerging signals of Ni 0 and Mo 0 after reductive annealing agree with the formation of Ni‐Mo alloy. However, due to inevitable surface oxidation and surface‐sensitive nature of XPS technique, there were also considerable signals coming from the surface oxidized Ni and Mo species, an experimental phenomenon reported by several research groups on metal alloys . Similarly, different crystalline phases of Ni‐Ge and Ni‐Sn alloys or alloy mixtures were obtained by annealing the corresponding Ni‐LHS precursors at different temperatures (Figures S8 and S9, Supporting Information).…”

“…In the high-resolution XPS (HRXPS) spectra of Ni 2p (Figure 2c), the binding energies at 852.8 � 0.1 eV and 856.2 � 0.1 eV are indexed to Ni 0 and Ni 3 + , respectively. [44][45][46][47][48][49] The corresponding satellite peaks are located at the higher binding energies . In the HRXPS spectra of Mo 3d (Figure 2d), the peaks at 228.2 � 0.2 eV, 229.2 � 0.2 eV, 230.3 � 0.2 eV, and 232.3 � 0.2 eV eV are indexed to Mo 0 , Mo + 4 , Mo + 5 , and Mo + 6 , respectively.…”
