Heterostructures based on ZnO-TiO2/delaminated montmorillonite coated with Ag have been prepared by sol–gel and photoreduction procedures, varying the ZnO contents. They thoroughly characterized XRD, WDXRF, UV–Vis, XPS spectroscopies, N2 adsorption, SEM, TEM. In all cases, was effectively delaminated formation of TiO2 anatase particles anchored clay layer’s surface, yielding porous materials high surface areas. The structural textural properties heterostructures synthesized were unaffected...
Gold nanoparticles deposited on TiO2–Ni prepared by sol–gel process catalyses the CO oxidation to hydrogen purification. Gold-catalysts were characterized UV-Vis and Raman spectroscopies, X-ray diffraction, H2-TPR, N2 physisorption, HRTEM STEM-HAADF microscopies. These catalysts applied in water–gas shift reaction at temperatures from 30 300 °C this was studied DRIFTS understand catalytic surface phenomena. The best conversion showed doped Au/TiO2–Ni(1) with regard Au/TiO2 Au/TiO2–P25...
The photocatalytic degradation/adsorption process of the β -blocker atenolol (ATL) under UV irradiation is described using two types silver decorated catalysts: silver/titania and silver/titanates. ions were reduced on surface TiO 2 -P25- Degussa gallic acid. Silver/titanates prepared by a microwave-assisted hydrothermal method as starting material to obtain hydrogen titanate (H Ti 3 O 7 ) structure with tubular morphology. These materials characterized X-ray diffraction, UV-Vis...
Cu/Ti photocatalysts were prepared by the sol-gel process with different copper loadings (1.0, 2.5, and 5.0 wt.%) then thermally treated at several calcination temperatures from 400 to 600 °C. The materials characterized X-ray diffraction (XRD), N2 physisorption, Scanning Electronic Microscopy Energy Dispersive Spectroscopy (SEM-EDS), Ultraviolet-visible-Diffuse Reflection Spectroscopy, Ultraviolet-visible spectroscopy as a function of temperature, (Temperature Programmed Reduction)...
Abstract Photocatalytic degradation of Rhodamine B was carried out by decorated V 2 O 5 /NT and WO 3 titanate nanotubes with Pt (0.3 wt. %) under visible light irradiation. The effect parameters such as titanic acid phase, surface area photocatalyst load on the deactivation photocatalytic were studied. Photoatalysts characterized S BET , XRD, UV‐vis, XPS, HR‐TEM, H ‐TPR. We found that Pt‐WO reached 90% dye in 60 min. 60% after 90 min 450‐nm irradiation pH neutral. incorporation nanoparticles...
