The electrical, optical and electrochemical performance of nanocomposite materials are higher compared to pure metal oxides. Recently, Tin (IV) oxide (SnO2)—Titanium dioxide (TiO2) nanocomposites have been widely studied because of their interesting physicochemical properties. SnO2–TiO2 nanocomposites can be used in as Li-ion batteries, gas sensors and photocatalysts thanks to their structural, optical, electrical and electrochemical properties. In this study, SnO2–TiO2 nanocomposites were obtained by using different surfactants by hydrothermal synthesis method. According to the results obtained, mesoporous SnO2–TiO2 nanocomposites without any impurities were obtained. Electrochemical properties of nanocomposites were investigated with a three-electrode cell system. The experiments were carried out in the potential range of–1 V/0 V and at different scanning rates of as 20–400 mV/s. Measurements were taken for each nanocomposite before and after 500 cycles. Specific capacitances were calculated for a scan rate of 400 mV/s. The highest specific capacitance values were obtained for nanocomposite prepared with Tween 80 as 251.6 F/g and 252.1 F/g for 500 cycles before and after, respectively. In addition, as a result of electrochemical impedance spectroscopy experiments, it was observed that nanocomposites exhibit typical capacitive behavior.
