Photocatalytic Activity of Sol−Gel-Derived Nanocrystalline Titania

K. V. Baiju, +4 more
- 05 May 2007 - 
TL;DR: In this paper, the photocatalytic activity of nanocrystalline titania (TiO2) powders has been investigated as a function of processing and material parameters through the decomposition of the methylene blue (MB) dye under exposure to ultraviolet (UV) radiation (λ = 200−400 nm) in an aqueous solution.
Journal ArticleDOI

Synergistic Effect in Photocatalysis As Observed for Mixed-Phase Nanocrystalline Titania Processed via Sol−Gel Solvent Mixing and Calcination

Ajesh K. Zachariah, +5 more
- 08 Jul 2008 - 
TL;DR: In this paper, the photocatalytic activity of mixed-phase nanocrystalline titania (TiO 2) processed via sol−gel SMC is measured by monitoring the degradation of the methylene blue dye in an aqueous solution, under UV-radiation exposure, using the UV−vis absorption spectroscope.
Journal ArticleDOI

Characterisation of stoichiometric sol–gel mullite by fourier transform infrared spectroscopy

P. Padmaja, +4 more
- 01 Nov 2001 - 
TL;DR: In this paper, the structural changes and coordination of Al and Si in the mullite system as a function of temperature (60-1400°C) were studied. But the results of the FTIR spectral patterns of the gel and the gel calcined at 200°C show bands corresponding to Al-O−Al and Si−O−Si vibrations, while at higher temperatures hydroxyl groups and organics present have been removed.
Journal ArticleDOI

Dehydroxylation and high temperature phase formation in sol-gel boehmite characterized by Fourier transform infrared spectroscopy

G. Krishna Priya, +4 more

Journal ArticleDOI

Photoregenerable, Bifunctional Granules of Carbon-Doped g-C3N4 as Adsorptive Photocatalyst for the Efficient Removal of Tetracycline Antibiotic

Suyana Panneri, +6 more
- 06 Jan 2017 - 
TL;DR: In this article, a simple aqueous spray drying process was used to obtain high surface area porous architecture of C3N4 nanosheets by using 2 wt% poly vinyl alcohol as binder.
