Opis:
InWO3-InMoO3 loaded-TiO2 nanomaterial was synthesised by co-precipitation method and sonication technique. The nanomaterial was characterized by High-resolution scanning electron microscopy (HR-SEM) with elementary dispersive X-ray (EDX), High-resolution transmission electron microscopy (HR-TEM), photoluminescence spectroscopy (PL) and UV-Vis diffuse reflectance spectroscopy (DRS). The photocatalytic activity of InWO3-InMoO3 loaded-TiO2 nanomaterial was studied from the photodegradation of methyl green (MEG) and methylene blue (MB) under UV-light irradiation at 365 nm. The hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. The mineralization confirmed by chemical oxygen demand measurements. A flaxisible mechanism is proposed for higher catalytic activity of InWO3-InMoO3-TiO2 under UV-light for 365 nm. This catalyst was found to be stable and reusable without appreciable loss of catalytic activity up to five cycles. The InWO3- InMoO3 loaded-TiO2 nanomaterial on MEG was high photocatalytic activity that of MB so high photocatalytic activity has been discussed by first order kinetics, rate constant value and high quantum yield. This material was showed increased hydrophobicity that of TiO2 electrochemical study and antibacterial activity of the analysis was also studied.

Opis:
Highly efficient CdO-SiO2 nanomaterial was synthesized by Sol-gel method and sonication technique. The nanomaterial was characterized by Field-emission Scanning electron microscopy (FE-SEM) with elementary dispersive X-ray (EDX), High-resolution transmission electron microscopy (HR-TEM), photoluminescence spectroscopy (PL) and Ultraviolet-Visible diffuse reflectance spectra (DRS). The photocatalytic activity of CdO-SiO2 nanomaterial was studied from the photodegradation of Rh B as it has maximum efficiency at pH = 7 under UV-light irradiation at 365 nm. The photodegradation of dye various Catalyst loading and dye concentration is parameters have been studied. The hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. The mineralization of dye is confirmed by chemical oxygen demand measurements. An achievable mechanism is proposed for higher activity of CdO-SiO2 under UV-light at 365 nm. This catalyst was found to be stable and reusable.

Opis:
TiO2 nanomaterial was prepared by precipitation method and sonication technique. The nanomaterial was characterized by HR-SEM with EDX, TEM, XRD, FT-IR and PL analysis. The photocatalytic activity of TiO2 was much better than that of TiO2–P25 under UV-light irradiation at 365 nm. The photocatalytic activity was evaluated from the photodegradation of malachite green (MAG). The influence of operational parameters such as the effect of catalyst loading dye concentration and chemical oxygen demand measurements had also been investigated. The Photodegradation was found to follow the pseudo-first-order kinetics. Hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. It was proposed that the catalyst is found to be stable and reusable.

Opis:
InWO3 -TiO2 nanocomposite material was synthesised by co-precipitation method and sonication technique. The synthesized nanomaterial was characterized by FE-SEM with EDX, HR-TEM, XRD, FT-RAMAN, AFM and BET surface area measurements. The photocatalytic activity of InWO3-TiO2 nanocomposite material was studied from the photodegradation of malachite green (MAG) under UV-light irradiation. The photodegradation of MAG at various parameters are reported. The Photodegradation was found to follow the pseudo-first-order kinetics. The Hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. The antimicrobial activity of the prepared nanomaterials has also been investigated. Cyclic voltammeter (CV)) measurements analysis of the prepared nonamaterial was discussed in detail. It was proposed that the catalyst was found to be stable and reusable.
