Template-free synthesis of mesoporous N-doped SrTiO3 perovskite with high visible-light-driven photocatalytic activity.
An effective, template-free synthesis methodology has been developed for preparing mesoporous nitrogen-doped SrTiO(3) (meso-STON) using glycine as both a nitrogen source and a mesopore creator. The N-doping, large surface area and developed porosity endow meso-STON with excellent activity in visible-light-responsive photodegradation of organic dyes.

متن کاملImmobilization of cobalt doped rutile TiO2 on carbon nanotubes walls for efficient photodegradation of 2,4-dichlorophenol under visible light
In this work, we focused on improvement of rutile-type TiO2 degradation efficiency by cobalt doping and decorating on carbon nanotubes walls (CNTs) (Co-TiO2/CNTs). We also synthesized pure TiO2, Co-TiO2 and TiO2/CNTs samples for control experiments. The textural and morphology features of the samples were characterized by a range of analyses including: XRD, FESEM/EDX. FTIR, TEM, UV-Vis DRS and ...
متن کاملPhotodegradation of Alachlor Over Fe - TiO 2 on Granular Activated Carbon Support under UV and Visible Light
Fe-TiO2 on granular activated carbon support was synthesized via hydrothermal method without calcination. The crystalline phases were identified using X-ray diffraction whereas the surface morphologies were examined using scanning electron microscopy. Peaks of anatase TiO2 and graphite were present in the Fe-TiO2-GAC sample. Comparisons of the surface features of GAC and Fe-TiO2-GAC show that F...
متن کاملSoft-Template Synthesis of Mesoporous Anatase TiO₂ Nanospheres and Its Enhanced Photoactivity.
Highly crystalline mesoporous anatase TiO₂ nanospheres with high surface area (higher than P25 and anatase TiO₂) are prepared by a soft-template method. Despite the high specific surface area, these samples have three times lower equilibrium adsorption (<2%) than Degussa P25. The rate constant of the mesoporous anatase TiO₂ (0.024 min-1) reported here is 364% higher than that of P25 (0.0066 min...
