Transition metal-doping could effectively extend the light response range of TiO2 photocatalysts from the ultraviolet (UV) to the visible region. Co-doped brookite titanium dioxide (Co–TiO2) photocatalysts were synthesized via the hydrothermal method with titanium tetrachloride as the raw material and cobalt chloride hexahydrate as the dopant. The prepared Co–TiO2 photocatalysts were characterized...
Yttrium and copper co-doped TiO2 catalysts were prepared by sol-gel method. The photocatalysts were characterized by means of XRD. By co-doping of Y3+ and Cu2+ not only could restrain the growth in size and aggregation of the nanoparticles, but also could effectively inhibit phase transformation from anatase phase to rutile. The reduction of CO2 showed that the nano Y-Cu/TiO2 obtained obvious photocatalytic...
