Rutile TiO₂ with highly active facets has attracted much attention owing to its enhanced activity during the photocatalytic degradation of pollutants such as pharmaceuticals in wastewater. However, it is difficult obtain by controlling synthetic conditions. This paper reports a simple hydrothermal synthesis rutile nanorods exposed {110} facets. The obtained was characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission (HR-TEM), and Raman...
In the present work, nano-sized TiO2 polymorphs (anatase, brookite, and rutile) were synthesized via hydrothermal treatment of an amorphous titania. Three characterized by XRD, Raman spectroscopy, SEM, UV–Vis DRS, N2-sorption measurements. The photocatalytic degradation experiments performed with low catalyst concentration, high organic loading under a 60 W solarium lamp irradiation. was monitored spectroscopy TOC Cinnamic acid, ibuprofen, phenol, diatrizoic acid dyes rhodamine B rose bengal...
Binary copper oxides with different ion oxidation states including cuprous Cu2O and cupric CuO have already been successfully synthesized by the simple highly repeatable grow-up technique from modified Cu sheet. By controlling annealing time temperature, oxide (CuO, Cu2O) composites were hierarchically formed on surface. All obtained samples characterized using X-ray diffraction (XRD) spectroscopy scanning electron microscopy (SEM). The results showed that sheets after in air yielded mixture...
Abstract: To solve several noticeable problems in cleaning surfaces that may expose bacteria, the beeswax- and CTAB-assisted synthesis of cubic-shaped Cu2O nanostructures is successfully achieved form suspension with an average particle size 100 nm. This unique material a distinct cubic morphology beeswax shell well-defined core are clearly observed core-shell structure. The Cu2O/beeswax/CTAB materials exhibit vigorous antimicrobial activity against common strains bacteria fungi such as E....
Abstract A highly efficient and stable photocatalyst, Ag 3 PO 4 , was prepared using a simple co-precipitation method at room temperature. The precursors used in this process were AgNO K 2 HPO . resulting photocatalyst forms irregularly-shaped spheres with diameters ranging from 300 to 1 μm. shape of the slightly changes when different surfactants (PVA, PVP, PEG) are used. powdered exhibits excellent visible light-driven photocatalytic performance. It is capable decomposing rhodamine B (RhB)...
Silver as a metal catalyst has been used to remove odorous compounds. In this study, silver particles in nano sizes () were prepared on the surface of , supporting material, using sputtering method. The nano-particles dispersed by dissolving into water, and aqueous phase was applied inorganic odor compounds, scrubbing reactor. Since ammonia high solubility, it removed from gas even spraying water scrubber. However, concentration nitrate ion increased only nano-particle solution, implying...
