“…No secondary phase is observed in the synthesised SnO 2 , revealing the high purity of the sample. Usually, SnO 2 crystallises in its tetragonal rutile structure in hydro/solvothermal treatment [23,30,31,42]. In our study, the presence of solvent (ethanol) with an external temperature of 100°C leads to the formation of orthorhombic SnO 2 phase.…”

Tin dioxide (SnO 2 ) nanoparticles (NPs) are synthesised via a direct (one-step) solvothermal route in the presence of ethanol as a solvent. The as-synthesised SnO 2 is well characterised by various analytical techniques such as X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy and BET surface area analyses. The powder X-ray diffraction study reveals that the synthesised oxide adopts orthorhombic SnO 2 crystal structure. The transmission electron microscopic investigation shows the formation of nanoparticles with an average size of 6.44 nm. Moreover, the influence of the solvent on morphological and textural properties of as-synthesised SnO 2 is also explained. Further, the as-synthesised SnO 2 nanoparticles are employed for Friedel-Crafts benzoylation of anisole to produce 4-methoxybenzophenone. Various reaction parameters viz. effect of reaction temperature, effect of catalyst dosage, effect of solvation, and substrate ratio are also addressed for the acylation reaction. The SnO 2 NPs exhibit high catalytic activity for the acylation reaction of anisole. They also show high stability for the benzoylation with good recyclability up to five consecutive cycles.

“…The SnO 2 NPs is widely used as sensors, conducting electrode, rechargeable batteries, optical and electronic devices (Hu et al 2002, Liu et al 2005, Yeow et al 2009. Numerous procedures have been reported for the synthesis of SnO 2 NPs including sol-gel, hydrothermal, co-precipitation, solvothermal, chemical vapor deposition and carbothermal reduction process (Leite et al 2002, Fujihara et al 2004, Liu et al 2005, Qiao et al 2014, Bhagwat et al 2015, Nadaf and Venkatesh 2016. However, the use of plant materials for the synthesis of nanomaterials is more advantageous due to its easy handling, environment friendly and economical nature (Haq et al 2016).…”

The tin dioxide nanoparticles (SnO 2 NPs) were fabricated via eco-friendly process using Daphne mucronata (D. mucronata) leaves extract as capping and reducing agent. The N 2 adsorption/ desorption experiment was performed to determine the surface area by Brunauer-Emmett-Teller (BET) method and S BET was found to be 147 m 2 g −1 . The crystalline nature and lattice parameter was studied by x-ray diffraction (XRD) and calculated crystallite size is 15.63 nm. The surface morphology was examined by scanning electron microscopy (SEM) and the estimated average particle size is 64 nm. The percentage composition and purity of the SnO 2 NPs was determined by energy dispersive x-ray (EDX). The raman active modes were identified by using raman spectroscopy while functional groups upon the surface were studied by using fourier transform infrared (FTIR) spectroscopy. The photocatalytic performance of SnO 2 NPs was examined against Rhodamine 6G (R6G) and 99.70% rhodamine 6G (R6G) were degraded in 390 min with the degradation rate of 0.0148 per min. The SnO 2 NPs were screened against the selected microorganisms and the order of antimicrobial activity is given as; Gram negative bacteria (GNB)>Gram positive bacteria (GPB)>fungi.

SnO 2(1-x) ZnO (x) (with x values 0.0,0.2,0.4,0.5,0.6,0.8,1.0) nanocomposite was prepared by a simple microwave assisted solvothermal method using ethylene glycol as solvent. The as-prepared samples are calcinated at 500 0 C. They were characterized using powder X-ray diffraction (PXRD) and the AC electrical parameter was studied with in the temperature range of 40-150 0 C. Both the dielectric loss factor and dielectric constant decreases with increase in frequency and increases with increase in temperature. It is due to the occurrence of space charge polarization. Increase in AC electrical conductivity with increase in frequency and temperature was noted and it is due to hopping of electrons. The results are reported here with.
