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 ...

In the present study, silver-doped TiO2 (Ag/TiO2) nanoparticles were prepared by various Ag doping (wt%) and a combination of sol-gel and ultrasound irradiation. Ag/TiO2 nanoparticles were characterized by energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. Based on the Taguchi method, photocatalytic...

This work presents the photocatalytic property of electron beam evaporated titanium dioxide (TiO2) thin films prepared at room temperature. The films were investigated for decomposition of methylene blue – eosin dye solution under visible light irradiation. The effect of annealing on structural, optical and decomposition properties was studied in detail. X-ray diffraction study revealed the amo...

Due to the pollution of dyeing and textile industry wastewaters in different colors and the need to remove these pollutants from the wastewaters, it is necessary to study and develop effective and efficient technology solutions required. To remove dye from aqueous solutions, photodegradation is employed as an effectively simple way. Thus, the BiOBr photocatalyst was chemically made by synthesis...

The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...

The heterogeneous photo-Fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. The photocatalyst has been prepared by coprecipitation method. The rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. It has been observed thatphotocatalytic degradation follows pseudo first order kinetics. The effect of various param...

A SeO2 ethanol solution as the facile precursor has been used for the preparation of quaternary Cu2ZnSnSe4 (CZTSe) nanoplates. Monodispersed single-phase CZTSe nanoplates have been prepared successfully by a facile one-pot thermal chemical method. The as-prepared CZTSe nanoplates show uniform morphology with a bandgap of ~ 1.4 eV. As a proof of concept, the CZTSe nanoplates have been used as a ...
