“…SDS-TiP nanocomposite was prepared by drop wise addition of 0.1 M Titanium chloride solution prepared in CCL 4 into mixture of 0.1 phosphoric acid and sodium dodecyl sulphate in different mixing volume ratios at constant temperature (25 ± 1 °C) [12].White precipitate of ion exchanger SDS-TiP was obtained. The rest processes were similar as reported earlier [9,25].…”

In this paper, a facile and highly efficient nanocomposite sodium dodecyl sulphate-based titanium(IV) phosphate (SDS-TiP) was successfully synthesized by sol-gel method. The surface morphology, crystalline structure, and optical properties were characterized by FTIR, XRD, TGA-DTA, SEM, TEM and UV-Vis diffuse reflectance spectroscopy (DRS). The physiochemical properties such as pH titration, elution behavior and chemical stability of SDS-TiP were studied. The ion exchange capacity of SDS-TP was found to be higher (1.6 meq g −1 ) for Na + ion as compared to their non-SDS material (1.1 meq g −1 ). For optimal adsorption of metal ions, sorption studies were performed in different solvent systems showing higher distribution coefficient (K d ) values. The SDS-TiP nanocomposite is active as a catalyst under visible light having optical absorption wavelength below 600 nm and the band gap obtained was 3.2 eV indicating that the material is behaving as a semiconductor. The higher photocatalytic activity of SDS-TiP is attributed due to the structure of the catalyst, optimal amount of SDS-TiP (5 g/dm 3 ) and the initial concentration of methylene blue (MB) was found to be 20 ppm. It was observed that 90% of MB dye was removed after exposure to solar radiation for short duration. SDS-TiP can be effectively used as a highly efficient photocatalyst for the decomposition of MB dye as well for the removal of metal ions.

Polyaniline-Sn(IV)iodophosphate (PANI-SnIP) nanocomposite cation exchanger was synthesized via the sol-gel approach and its AC and DC electrical conductivity, dielectric properties and optical properties were studied. The characterization of the nanocomposite using FT-IR, UV-Vis spectroscopy, SEM and TEM showed the formation of a nanocomposite with improved physicochemical properties. The AC electrical conductivity was found to increase with the increase in applied frequency and concentration of the Sn(IV)iodophosphate (SnIP) filler content. The optical band gap of the nanocomposite decreased from 3.99 eV for pure polyaniline (PANI) to 3.60 eV for the nanocomposite with 30% SnIP content. The ethanol vapor sensing characteristics were evaluated by the fabrication of a PANI-SnIP nanocomposite as a sensor for ethanol vapor detection. The sensing performance of the nanocomposite was markedly improved with the increase of SnIP concentration. The nanocomposite sensor exhibited a linear response to the variable concentration of ethanol (50, 100, 300, and 500 ppm), a quick response time, and a reproducible and reversible response, which are a clear manifestation of its sensing ability and environmental utility.
