N, S-Codoped TiO2/Fe2O3 Heterostructure Assemblies for Electrochemical Degradation of Crystal Violet Dye
In contemporary research, “Heterostructure” assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitate faster charge carrier transport across the material interfaces. The improved/enhanced efficiency metrics in these systems (electro/photo-electrochemical processes/devices) is due to synergistic interaction and synchronized charge transport a...
متن کاملAcidic Peptizing Agent Effect on Anatase-Rutile Ratio and Photocatalytic Performance of TiO2 Nanoparticles
TiO2 nanoparticles were synthesized from titanium isopropoxide by a simple peptization method using sulfuric, nitric, and acetic acids. The effect of peptizing acid on physicochemical and photocatalytic properties of TiO2 powders was studied. The structural properties of synthesized TiO2 powders were analyzed by using XRD, TEM, N2-physisorption, Raman, DR UV-vis, FTIR, and X-ray photoelectron s...
متن کاملEnhanced Photocatalytic Activity of Polypyrrole/TiO2 Nanocomposites for Acid Violet Dye Degradation under UV Irradiation
Abstract-In-situ chemical polymerization was used to synthesize PPy/ TiO2 nanocomposite. The nanocomposite was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDX) to ensure the crystallite size, functional groups and morphology of the polymer nanocomposite. The band gap of th...
متن کاملBand alignment of rutile and anatase TiO2
The most widely used oxide for photocatalytic applications owing to its low cost and high activity is TiO2. The discovery of the photolysis of water on the surface of TiO2 in 19721 launched four decades of intensive research into the underlying chemical and physical processes involved2–5. Despite much collected evidence, a thoroughly convincing explanation of why mixed-phase samples of anatase ...
متن کاملUnderstanding the effect of surface/bulk defects on the photocatalytic activity of TiO2: anatase versus rutile.
The sole effect of surface/bulk defects of TiO2 samples on their photocatalytic activity was investigated. Nano-sized anatase and rutile TiO2 were prepared by hydrothermal method and their surface/bulk defects were adjusted simply by calcination at different temperatures, i.e. 400-700 °C. High temperature calcinations induced the growth of crystalline sizes and a decrease in the surface areas, ...
