The micropores regarding the material had been constructed by subsequent annealing. The outcome regarding the experiments reveal that the 3DPS-based sensor's reaction is strongly determined by heat, displaying a mountain-like reaction curve. The maximum sensor susceptibility (Ra/Rg) was found become up to 505.7 at a heating heat of 153 °C sufficient reason for an exposure to 100 ppm acetone. Furthermore, at 153 °C, the sensor nonetheless had an answer of 2.1 when exposed to 50 ppb acetone gas. The 3D
