Surface and Interface Engineering of Moni Alloy Nanograins Bound to Mo-Doped Nio Nanosheets on 3d Graphene Foam for High-Efficiency Water Splitting Catalysis

Three-Dimensional Strawlike MoSe2-Ni(Fe)Se Electrocatalysts for Overall Water Splitting

“…235.22 eV) still exist, but the intensity of the Mo 4+ peaks becomes higher and a set of peaks attributed to Mo 0 appear at the binding energy of 226.45 and 229 45. eV, indicating that high-valent Mo is reduced to low-valent Mo during the HER process 55,56. In the Se 3d core spectrum (Figure5e), Se 3d 5/2 and Se 3d 3/2 are obtained at 55.18 and 55.78 eV, respectively, which can be classified as Se 2− .…”
