Photocatalytic degradation of methylene blue dye over immobilized ZnO nanoparticles: Optimization of calcination conditions
In the present study, calcination conditions during the synthesis of zinc oxide nanoparticles were optimized using response surface methodology (RSM) based on central composite design (CCD). After that, the effect of the type of UV irradiation on the photocatalysis of methylene blue (MB) dye was studied based on the kinetic model obtained at optimum conditions. Analysis of variance (ANOVA) exhi...
متن کاملPhotocatalytic degradation of Methylene blue dye and Chromium metal from wastewater using nanocrystalline TiO2 Semiconductor
This paper describes the basics of photocatalysis on semiconductors, mainly on TiO2 and the application of photocatalytic processes for water purification from organic and inorganic matter as well as metal removal introduced in order to improve the photocatalytic action of titanium dioxide. The photocatalytic activity of anatase phases of nanocrystalline TiO2 for the degradation of different su...
متن کاملAdsorption and photocatalytic degradation of methylene blue over hydrogen-titanate nanofibres produced by a peroxide method.
In this study, Degussa P25 TiO2 was partially dissolved in a mixture of hydrogen peroxide and sodium hydroxide at high pH. The fabrication of nanofibres proceeded by the hydrothermal treatment of the solution at 80 °C. This was followed by acid wash in HCl at pH 2 for 60 min, which resulted in the formation of hydrogen-titanate nanofibres. The nanofibres were annealed at 550 °C for 6 h to produ...

متن کاملPhotocatalytic Degradation of Amaranth Dye over Immobilized Nano-crystals of TiO2
-The present work is focused on the heterogeneous photocatalytic degradation of Amaranth dye over immobilized nano-crystals of TiO2. Immobilization has been an acceptable approach to overcome the drawbacks encountered with powder suspensions. Immobilization is performed using polyvinyl alcohol-formaldehyde binder. This method of immobilization does not require thermal heating at high temperatur...
