Adsorption and photocatalytic performance of bentonite-titanium dioxide composites for methylene blue and rhodamine B decoloration
Bentonite - TiO2 composites were prepared by impregnation of TiO2 and bentonite, followed by microwave irradiation processes. The composites were characterized using FTIR, SEM, XRD, and nitrogen sorption methods. Anatase phase of TiO2 in all composites are observed through XRD diffraction peaks and surface morphology of the composites. The adsorption and photocatalytic capabilities of the compo...
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 کاملEfficient Immobilised TiO2 in Polyvinylidene fluoride (PVDF) Membrane for Photocatalytic Degradation of Methylene Blue
Immobilised titanium dioxide (TiO2) in membrane structures has recently become attractive. This is due to the elimination of the separation step after the process of photocatalytic degradation. The efficiency of the TiO2 surface area exposed to UV light as the main important parameter needs to be considered. The immobilisation of TiO2 nanoparticles in the polyvinylidene fluoride (PVDF) membrane...
متن کاملHydrothermally synthesized nanocrystalline Nb2O5 and its visible-light photocatalytic activity for the degradation of congo red and methylene blue
Nb2O5 nanoparticles were synthesized by the hydrothermal method. Structural, morphological and elemental analysis of synthesized Nb2O5 nanoparticles was carried out using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy, respectively. The average crystal size calculations were performed on the basis ...
متن کاملPreparation, Characterization, and Application of Nanospherical α-Fe2O3 Supported on Silica for Photocatalytic Degradation of Methylene Blue
In the research, spherical α-Fe2O3 NanoParticles (NPs) were synthesized through Forced Hydrolysis and Reflux Condensation (FHRC) process and were supported on the surface of silica sand by Solid-State Dispersion (SSD) method. Characterization of silica and α-Fe2O3/SiO2 catalyst was done using Fourier-Transform InfraRed (FT-IR) spectrosc...
