Divergent Bandgap Responses in Cu- and Zn-Doped NiTiO 3 Nanoparticle

This study demonstrates that Cu and Zn doping of NiTiO₃ nanoparticles yield divergent bandgap responses due to their distinct electronic configurations, where Cu²⁺ introduces impurity states that significantly narrow the bandgap and enhance visible-light photocatalytic activity, while Zn²⁺ has a negligible effect.
