GREEN CONGLOMERATE AND INVESTIGATION USING AQUEOUS EXTRACTION FROM DATURA METAL LEAVES FOR CUPROUS OXIDE NANOPARTICLES

Journal of Emerging Technologies and Innovative Research (2018)

K. Prathap Kumar N. Sabari Arul

The Cuprous Oxide (Cu2O) nanoparticles were synthesized by green synthesis method using copper as precursor and Ammonium chloride with Lactobacillus bulgaricus as reducing agent in presence of Datura metal leaf extract as bio-surfactant in an aqueous medium. The bio synthesized nanoparticles were describe the distinctive natured by X-ray diffraction (XRD) and the pattern unveil face centered cubic structure. The size of Cu2O nanoparticles were observed by scanning electron microscopy (SEM). The results indicate that the Cu2O nanoparticles have high purity and the average particles size is 32 nm. The elemental anatomy of matals has been identified by Energy Dispersive X-Ray Analysis (EDX). Also conducting Inductive Couple Plasma (ICP) for its propensity to identify and quantify all elements with the exception of Argon

Strong quantum confinement effects in kesterite Cu2ZnSnS4 nanospheres for organic optoelectronic cells

Nanoscale (2013)

N. Sabari Arul Dong Yeol Yun Dea Uk Lee Tae Whan Kim

X-ray photoelectron spectra, X-ray diffraction patterns, scanning electron microscopy images, and high-resolution transmission electron microscopy images showed that the as-prepared samples were Cu2ZnSnS4 (CZTS) nanospheres with a kesterite phase. Ultraviolet-visible absorption spectra for the CZTS nanospheres with an average crystallite size of 3.26 nm showed that the absorption edge corresponding to the energy gap shifted to the higher energy side due to the quantum confinement within the CZTS nanoparticles. Current–density measurements showed that the power conversion efficiency (0.952%) of the organic photovoltaic cells with CZTS nanospheres was much higher than that (0.120%) of the cells without CZTS nanospheres.

Room Temperature Growth of Cerium-Iron Oxide Nanorods

Advanced materials research (2010)

N. Sabari Arul D. Mangalaraj N. Ponpandian Pao Chi Chen Junsin Yi

Cerium-iron oxide composite nanorods were synthesized by a surfactant free precipitation method. The synthesized products were characterized by XRD, FESEM, BET and TEM. Increase in the mole concentration causes the morphology of the cerium oxide to change from nanorods into nanocubes. X-ray diffraction pattern shows a diffraction peak at 28.5° corresponding to (111) reflection plane normal to c axis of a cubic fluorite structure of CeO2 and also hexagonal phase of Fe2O3 and orthorhombic phase of FeO (OH). EDAX analysis on individual nanorod conform the presences of Iron, which supports the XRD spectra. From transmission electron microscopy (TEM), the length and width of the nanorods were estimated in the range of ~100-350 nm and ~20-40 nm respectively. The Brunauer Emmett Teller (BET) analysis showed the increase in surface area for the obtained nanorods with respect to the increase in Fe concentration which in turn enhanced the formation and growth of nanorods.

Solvothermal synthesis of three‐dimensional CeO₂ micropillows and their photocatalytic property

physica status solidi (RRL) - Rapid Research Letters (2014)

N. Sabari Arul D. Mangalaraj Jeong In Han

Abstract Three‐dimensional (3D) CeO 2 micropillows were synthesized by using solvothermal method. The pH of the precursor solution was adjusted to 10 by adding ammonium hydroxide. The structural, morphology and compositional characteristics of CeO 2 micropillows were investigated by XRD, SEM, TEM and EDAX. XRD analysis showed the formation of CeO 2 micropillows. BET analysis showed high specific surface area for the synthesized CeO 2 micropillows (191 m 2 g –1 ). Optical absorption of CeO 2 micropillows showed enhanced photoabsorption ability with the estimated band gap energy of 2.8 eV. The photodegradation rate of the CeO 2 micropillows was found to be 87% and obeys pseudo‐first‐order equation. The photocatalytic results indicated that the CeO 2 micropillows exhibit enhanced photocatalytic property towards azo dye acid orange 7 (AO7) under UV–Vis light illumination. magnified image (© 2014 WILEY‐VCH Verlag GmbH & Co.

Kinetics and Photodegradation Study of Congo Red using Mg with Ti/Al Co-Doped ZnO Nanocomposite under UV Light

Asian Journal of Chemistry (2019)

N. Sabari Arul T. Senthilnathan

ZnO nanocomposites co-doped with dopants like Mg with Ti or Al were prepared and assigned as ZnO-A and ZnO-B. All the nanocomposites were characterized by XRD, SEM and EDX and its utility towards the photodegradation of Congo red is studied. The present study was carried out in 30 W mercury lamp fitted in batch photoreactor and the effect of decomposition was measured in UV-absorption. Nanocomposite with combination of Ti dopant (ZnO-A) exhibited effective degrading ability to aqueous Congo red solution. A solution of 100 ppm of above concentrated ZnO nanocomposite solution was reduced nearly to 5ppm within 5 h. The photodegradation kinetics revealed that the photodegradation of aqueous Congo red follows first order reaction and showed quite comparable degradation effeciency with earlier reports.
