A series of Al-doped Na-TiO2 nanorods (AlTi-nR-x) varying the Al2O3/TiO2 (Al/Ti) ratio was synthesized by hydrothermal method. TEM results revealed well-defined nanorod like shape morphology. XPS results confirmed the presence of Al inside the samples and a slight increase in electron density around the Ti atom. Calcined materials were evaluated in the CO2 hydrogenation (HYD) in a continuous flow-microreactor...
A series of WO3 supported on TiO2 catalysts were prepared by impregnation method with varying WO3 content. The prepared catalysts were characterized by FT-IR, Laser Raman, X-ray diffraction, BET surface area and temperature programmed desorption of NH3. X-ray diffraction and Laser Raman spectroscopic results suggest that WO3 was highly dispersed on titania up to 15 wt%. Acidity of the catalyst depended...
