Heterostructured g-CN/TiO Photocatalysts Prepared by Thermolysis of g-CN/MIL-125(Ti) Composites for Efficient Pollutant Degradation and Hydrogen Production.

Photocatalysts composed of graphitic carbon nitride (g-CN) and TiO were efficiently prepared by thermolysis of the MIL-125(Ti) metal organic framework deposited on g-CN. The heterojunction between the 12 nm-sized TiO nanoparticles and g-CN was well established and the highest photocatalytic activity was observed for the g-CN/TiO (3:1) material. The g-CN/TiO (3:1) composite exhibits high visible light performances both for the degradation of pollutants like the Orange II dye or tetracycline but also for the production of hydrogen (hydrogen evolution rate (HER) up to 1330 μmolhg and apparent quantum yield of 0.

CdSe nanorod/TiO nanoparticle heterojunctions with enhanced solar- and visible-light photocatalytic activity.

CdSe nanorods (NRs) with an average length of ≈120 nm were prepared by a solvothermal process and associated to TiO nanoparticles (Aeroxide P25) by annealing at 300 °C for 1 h. The content of CdSe NRs in CdSe/TiO composites was varied from 0.5 to 5 wt %.

High performance Ce-doped ZnO nanorods for sunlight-driven photocatalysis.

Ce-doped ZnO (ZnO:Ce) nanorods have been prepared through a solvothermal method and the effects of Ce-doping on the structural, optical and electronic properties of ZnO rods were studied. ZnO:Ce rods were characterized by XRD, SEM, TEM, XPS, BET, DRS and Raman spectroscopy. 5% Ce-doped ZnO rods with an average length of 130 nm and a diameter of 23 nm exhibit the highest photocatalytic activity for the degradation of the Orange II dye under solar light irradiation.
