N2 - Bandgap modification of TiO2 has been achieved through a conceptually new non-compensated co-doping for enhanced solar energy utilization, guided by theoretical modeling and simulations. A wet chemical approach was used to prepare Cr-N co-doped TiO2 nanoparticles. XPS results show that both Cr and N have been successfully incorporated into TiO2. UV-Vis co-doped TiO2 exhibit significantly enhanced absorption compared to either N-doped TiO2 or Cr-doped TiO2. STS spectra showed that the bandgap energy was reduced to about 2.0 eV for co-doped TiO2.
