visible light irradiation. Xing et al. [21] prepared the highly dispersed carbon and
lanthanum co-doped TiO 2 crystals with exposed (001) facets by using glucose as the
carbon-doping source and (001)-facet-controlling agent through a simple one-step
hydrothermal method. The C doping was responsible for the strong absorption in the
visible light region, and the La doping acted as the electron capture center. The
