Tin oxide nanoparticles with a narrow size distribution were prepared by pulsed laser ablation of a pure tin target both in aqueous solutions and in pure water. Laser beam of 266 nm, 355 nm and 532 nm from an Nd :YAG laser were applied and the wavelength effects on preparation of tin oxide particles were examined. The particle size and phase structure were characterized by using transmission electron microscope (TEM). The observation revealed that the particle size of the nanoparticles was about 2–5 nm. Chemical components of obtained nanoparticles were analyzed by using an energy dispersive X-ray analysis (EDX) and the results demonstrated that the nanoparticles mainly consisted of Sn and O elements. Furthermore, aqueous solutions of sodium dodecyl sulfate (SDS) were used to study the influence of surfactant concentration on the formation of tin oxide nanoparticles. When the surfactant reached critical micelle concentration, relatively stable colloidal suspensions consisting of well-dispersed tin oxide nanoparticles were obtained. UV-vis spectrometer was used to measure the absorption of suspensions of tin oxide nanoparticles.

Influence Of Ph

A systematic study on the preparation of tin oxide nanoparticles using the precipitation method has been conducted. The preparation of nanomaterials was by varying reaction parameters such as pH and temperature. The tin oxide nanoparticles were characterized by using AFM, SEM, XRD and UV-Vis. Particle size was obtained using XRD studies the value is 28.8 nm, 35.2 nm, 30.8 nm and 33.8 nm. It was found that the alteration of pH and temperature changes the particle size.

Reduction Of Co2

Gas sensors fabricated with antimony doped tin oxide (ATO) nanomaterials exhibit remarkable sensitivity for detecting oxidizing and reducing gases. This study highlights the enhanced selectivity and stability of the porous ATO nanomaterial electrode made for electrochemical reduction of CO2 in aqueous media. During electrochemical reduction, these electrodes prepared from compressed powders tend to crumble within a few hours in aqueous media. To overcome this electrode disintegration effect, we modified the surface of the doped tin-Oxide nanoparticles with Nafion and a dipodal silane (1,2-Bis(triethoxysilyl)ethane). The electrode characterization studies include Cyclic Voltammetry (CV), and Electrochemical Impedance Spectroscopy (EIS). Scanning electron microscopic investigation of electrode surface morphology and roughness before and after electrochemical CO2 reduction for derivatized and underivatized electrode revealed lower surface roughness for former than the latter.The derivatized electrodes allowed CO2 electrochemical reduction at low overpotentials and high current density without any electrode crumbling over more than 24 hours of continuous operation. Formate/formic acid and methanol were the major products of reduction at electrode potentials ranging from -0.4 to -1.0V vs. RHE in the CO2 saturated 0.1M KHCO3 electrolyte. Higher current density and Faradaic Efficiency of formic acid was observed when compared to planar tin electrode materials and tin oxide nanoparticles deposited on FTO glass.

A brisk and one-step green method of stannic oxide (Tin oxide) nanoparticles synthesis from the fruit essence of Averrhoa bilimbi has been described in this paper. Nanoparticle was synthesized using the method of co-precipitation and reduction with plant extract. The synthesized tin oxide nanoparticles have been characterized using different analytical techniques. Characterization was performed using UV-Vis Diffuse Reflectance Spectroscopy, Fourier-Transform Infrared Spectroscopy, Scanning Electron Microscopy, High-resolution Transmission Electron Microscopy, Energy Dispersive Spectroscopy, and X-ray Powder Diffraction. UV-Vis spectrum showed an absorbance in the range of 280 nm to 290 nm. The scanning electron microscopy analysis revealed the spherical morphology of the green synthesized nanoparticles and the energy-dispersive spectroscopy spectrum sights the intense peaks of Sn and O which validate the constitution of tin oxide nanoparticle. Further, X-ray diffraction analysis confirmed the formation of SnO2 nanoparticles in tetragonal crystal structure and the crystalline size of the nanoparticles estimated falls in the range of 2.6 nm. The nanoparticles size is determined to be at close range of 3.08 nm from the transmission electron microscopy studies. The exertion of the SnO2 nanoparticles was found against Klebsiella aerogenes and Staphylococcus aureus. Biosynthesized SnO2 nanoparticles showed antioxidant activity too. These findings support the use of tin oxide nanoparticles in distinct applications remarkably in medical field. SnO2 nanoparticles synthesis using the Averrhoa bilimbi fruit extract is being reported for the first time in this study to the best of our knowledge
