نویسندگان
چکیده
Stannous oxide (SnO) micro sheets were successfully synthesized by the hydrothermal alkaline solution method and characterized X-ray diffraction, scanning electron microscopy, transmission energy-dispersive spectroscopy, Brunauer-Emmett-Teller (BET) techniques. BET analysis confirmed a mesoporous structure with 33.8944 m2 g−1 specific surface area an average pore diameter of 6.488 nm. The resistance-based study SnO was performed for various volatile organic compounds (VOCs) at 100 °C. response sensor is maximum toward ethanol good (∼2 s)/recovery (∼11 s) time optimum working temperature found to be °C gas. typically depends on state, gas diffusion, diameter, sensor, crystallite size material. (29.251 nm) strain (8.952 × 10−4) particles analyzed Williamson-Hall Plot. target gases validated Knudsen diffusion coefficient (Dκ). Dκ value 8.962 1011 nm s−1 °C, which among obtained values other VOCs.
