(a) Response of pristine SnO2 sensors and PtAu/SnO2 sensors to 100 ppm acetone at various temperature values. (b) Selectivity test of PtAu/SnO2 sensors against 100 ppm of NH3, CH3COCH3, C2H5OH, CH3OH, C7H8, C8H10, C6H6, C6H14, and HCHO at 300 °C. (c) Dynamic response plots of PtAu/SnO2 materials to varying amounts of acetone (0.166–100 ppm) at 300 °C. (d) Linear response of PtAu/SnO2 sensors with acetone gas concentration.
