a High-resolution XPS spectra of Ni 2p for NiPS3 UNSs, 20.0N and 30.0N. b Synchrotron-based XANES S L edge of 0.0N, 20.0N and 30.0N. c EELS spectra of Ni L2,3 edge for NiPS3 UNSs and 20.0N. Average potential profiles along the z axis direction of d CdS (200) crystal facet and e NiPS3 (002) crystal facet. f The differential charge density map of NiPS3/CdS system. The golden and cyan iso-surfaces indicate the area of net-electron accumulation and deficit, respectively. The work functions and differential charge density map were calculated considering the solvation effect in 17 vol% triethanolamine aqueous solution.
