    Tin oxide nanoparticles are prepared by electrochemical reduction   method using tetrapropylammonium bromide (TPAB) and   tetrabutylammonium bromide (TBAB) as structure directing agent in   an organic medium viz. tetrahydrofuran (THF) and acetonitrile   (ACN) in 4:1 ratio by optimizing current density and molar   concentration of the ligand. The reduction process takes place   under an inert atmosphere of nitrogen over a period of 2 h. Such   nanoparticles are prepared by using a simple electrolysis cell in   which the sacrificial anode as a commercially available in tin   metal sheet and platinum (inert) sheet act as a cathode. The   parameters such as current density, solvent polarity, distance   between electrodes and concentration of stabilizers are used to   control the size of nanoparticles. The synthesized tin oxide   nanoparticles are characterized by using UV–Visible, FT-IR and   SEM–EDS analysis techniques. UV-Visible spectroscopy has revealed   the optical band gap to be 4.13, 4.16 and 4.24 ev for (8, 10 and   12 mA/cm 2) and the effect of current density on theirs particle   size, respectively.
