چکیده
A RuO2-CdS-Ti-MCM-48 mesoporous material has been prepared. This composite material generates hydrogen and oxygen in the absence of a Pt co-catalyst and most importantly photocorrosion of CdS is completely eliminated.

Synthesis of mesoporous TiO2-SiO2-Ag and investigation of its structural and photocatalytic properties under visible light and ultra-violate
In this project, mesoporous titanium oxide-silicon oxide doped by silver (TiO2-SiO2-Ag) was hydrothermally synthesized. Titanium isopropoxide, tetraethyl orthosilicate and silver nitrate were used as precursors for TiO2, SiO2 and Ag, respectively. Initially TiO2-SiO2 mesoporous nanocomposite was synthesized with weight ratios of silica to titania SiO2:TiO2:3:1 via hydrothermal method at 70˚C an...
متن کاملSynthesis and characterization of CdS nanoparticle anchored Silica-Titania mixed Oxide mesoporous particles: Efficient photocatalyst for discoloration of textile effluent
An efficient photocatalyst consisting of CdS nanoparticle dispersed mesoporous silica-titania was prepared using amphiphilic triblock copolymer P123 as template and silica-titania sol–gel precursors. The CdS nanoparticle was incorporated into silica-titania mesoporous nanosturctures by post impregnation method. The synthesized catalyst has been characterized by FTIR, TEM, SEM, and EDAX analysis...

In this work, we report synthesis and characterization of Bi2O3 nanoparticles loaded on mesoporous MCM-41 nanoparticles by a simple solid-state dispersion (SSD) method. Monoclinic bismuth oxide nanoparticles were prepared by polyacrylamide gel method and used as loading materials on the prepared mesoporous MCM-41 as a supporting material. Fourier transform infrared spectroscopy (FT-IR), X-ray p...
متن کاملMesoporous silica nanospheres decorated with CdS nanocrystals for enhanced photocatalytic and excellent antibacterial activities.
Uniform SiO2@CdS mesoporous nanospheres with an average diameter of 300 nm have been synthesized successfully by a facile process. The as-prepared mesoporous composite nanospheres have a BET-specific surface area of 640 m(2) g(-1) and an average pore size of 2.82 nm. The results demonstrated that more than 60% Rhodamine B (RhB) dye in solution (4.8 mg L(-1), 50 mL) could be removed by adsorptio...
