Study of Photocatalytic Degradation of Methyl Orange on Different Morphologies of ZnO Catalysts
In this study, several ZnO catalysts were prepared using different zinc sources as precursors. The different catalyst morphologies obtained were used to degrade photocatalytically a methyl orange (MO) dye solution, which was used to model wastewater pollution. The precursors, Zn(CH3COO)2, ZnCl2 and Zn(NO3)2, were individually added to a solution containing cetyltrimethylammonium bromide (CTAB) ...
متن کاملInvestigation of Photocatalytic Degradation of Methyl Orange by Using Nano-Sized ZnO Catalysts
Nano-sized ZnO catalysts were prepared by a direct precipitation method under the optimal conditions (calcination of precursors at 550 ̊C for 120 min). The as-synthesized ZnO catalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-Vis spectroscopy. The photocatalytic properties of ZnO nanoparticles were investigated via methyl orange (MO) as a model org...
متن کاملelectrocatalytic degradation of methyl orange on pbo2-tio2 nanocomposite electrodes
the electrocatalytic degradation of methyl orange (mo) on pbo2-tio2 nanocomposite electrodes was studied by cyclic voltammetry and bulk electrolysis. the results reveal that pbo2-tio2 nanocomposite electrodes possess higher oxygen evolution overpotential than pbo2 electrodes and the electrocatalytic degradation of mo on the electrodes is direct oxidation process. the influence of experimental p...
متن کاملFacile Fabrication of Cu2O Nanobelts in Ethanol on Nanoporous Cu and Their Photodegradation of Methyl Orange
Thin cupric oxide (Cu₂O) nanobelts with width of few tens of nanometers to few hundreds of nanometers were fabricated in anhydrous ethanol on nanoporous copper templates that was prepared via dealloying amorphous Ti40Cu60 ribbons in hydrofluoric acid solutions at 348 K. The Cu₂O octahedral particles preferentially form in the water, and nanobelts readily undergo the growth along the lengthwise ...
متن کاملThe Photocatalytic Kinetics of the Methyl Orange Degradation in the Aqueous Suspension of Irradiated TiO2
Background: In the present study, the photocatalytic (TiO2/UV) batch process has been used for the methyl orange (MO) degradation. Methods: In the catalyst range from 0.25 to 1.5 g/L, the optimum concentration of TiO2 was found to be 0.5 g/L. The kinetic behavior of MO degradation has been evaluated using the non-linear form of pseudo-first order and pseudo-second order models. Results: The g...
