Modification of TiO 2 with metal chalcogenide nanoclusters for hydrogen evolution [PDF]

, 2020
: Using density functional theory, corrected for on-site Coulomb interactions (DFT + U), we have investigated surface modification of TiO2 with metal chalcogenide nanoclusters for hydrogen evolution. The nanoclusters have composition M4X4 (M = Sn, Zn; X =
