Influence of La doping on the ethanol gas sensing properties of CdSnO3 micro-cubes

Synthesis of BaSnO3 as a Highly Dispersed Additive for the Preparation of Proton-Conducting Composites

“…After heating the sample at 600 °C, the reflections related to the crystalline BaSnO3 phase appear on the diffractogram, and the intensity of the diffraction peaks of the witherite BaCO3 phase decreases significantly. According to the data of thermal analysis at this temperature, the exothermic effect and chemical reaction (5) with the formation of CO2 are observed. These processes are associated with the crystallization process, the transition of the amorphous phase of barium stannate into the crystalline phase, and the formation of a nanocomposite, which is a mixture of BaSnO3 with residual unreacted nanocrystalline BaCO3 (Figure 5, curve 3).…”

Manganese doped two-dimensional zinc ferrite thin films as chemiresistive trimethylamine gas sensors

“…These defects facilitate the capture of additional electrons from the conduction band of the ZFM1 thin film. 110 As a result, they contribute to the expansion of the electron-withdrawing layer's thickness, ultimately enhancing the sensor's responsiveness, thereby increasing its chemical reactivity towards TMA. The suggested thin film sensor can be utilized as a cost-effective TMA sensing device, giving TMA manufacturing industries and transportation networks a reliable way to monitor the amount of trimethylamine (with fishy smell) in the environment.…”

Simultaneously Engineering Oxygen Defects and Heterojunction into Ho-Doped ZnO Nanoflowers for Enhancing n-Propanol Gas Detection

“…In the previous works of our group, an n -propanol gas sensor based on the LaFeO 3 /La 2 O 3 heterostructure exhibited a high response value of 4.3 toward 1 ppm n -propanol gas . From the aspect of element doping, the enhancement of gas-sensing performances, including response value − and stability, , through the doping of rare earth elements in metal oxides has been widely reported. − Meanwhile, ZnO, as an n-type semiconductor, finds diverse applications in catalysts, , nanogenerators, , electroluminescence, , and gas sensors. , Inspired by these advantages, a 5% La-ZnO film was prepared that demonstrated a higher response value (400%) to 500 ppm H 2 gas compared to pure ZnO (80%) . Zhao et al prepared Ce-doped ZnO nanowires, which were exposed to 100 ppm ethanol, and exhibited a higher response (25.3) than pure ZnO (7.4) .…”
