TiO 2 Electronic Properties Analysis: DFT Study of Ni and NiSe Doping Effect
Titanium dioxide (TiO 2 ) is a promising photocatalyst for hydrogen generation, but its efficiency is severely restricted by a wide bandgap and rapid electron-hole recombination. This study employs Density Functional Theory (DFT) to investigate the structural and electronic effects of isovalent Ni⁴⁺ doping and subs...
