Abstract

The development of one-step deposition technology for metal oxide-based coatings is significant for the rapid fabrication of gas sensors. Gas sensors based on LaFeO3 were fabricated by solution precursor plasma spraying (SPPS) strategy. Through a comparative analysis of material composition and cross-sectional morphology, we have determined the optimal spray distance (8 cm), ensuring the highest level of thickness uniformity in the coating (17.13 ± 0.34 μm). Furthermore, the influence of the number of passes on coating morphology and gas sensing performance was investigated. The optimal gas sensor possessed a higher response to isoamyl alcohol (236 at 25 ppm) at 250 °C. Meanwhile, excellent selectivity, repeatability, long-term stability (431.6 ± 9.2 at 60 ppm for 20 days), and a low limit of detection (144 ppb) were obtained. The superior low-concentration (< 25 ppm) gas-sensing performance should be ascribed to the loose porous morphology with uniform thickness and the higher surface activity of the optimal coating. Moreover, the practical experiment demonstrated the application potential of the sensors for monitoring wheat mildew. This work may provide a direction for the characteristic gas detection of wheat mildew and a successful case for the deposition of LaFeO3 coating by SPPS.

利用溶液前驱体等离子喷涂沉积高灵敏度 LaFeO3 涂层以检测异戊醇
开发基于金属氧化物涂层的一步沉积技术对于快速制造气体传感器意义重大。我们采用溶液前驱体等离子喷涂(SPPS)策略制造了基于 LaFeO3 的气体传感器。通过对材料成分和横截面形态的比较分析,我们确定了最佳喷涂距离(8 厘米),从而确保了涂层厚度的最高均匀性(17.13 ± 0.34 μm)。此外,我们还研究了喷涂次数对涂层形态和气体传感性能的影响。最佳气体传感器在 250 °C 下对异戊醇(25 ppm 时为 236)具有更高的响应。同时,还获得了极佳的选择性、重复性、长期稳定性(在 60 ppm 条件下,20 天的稳定性为 431.6 ± 9.2)和较低的检测限(144 ppb)。卓越的低浓度(25 ppm)气体传感性能应归功于厚度均匀的疏松多孔形态和最佳涂层的较高表面活性。此外,实际实验还证明了传感器在监测小麦霜霉病方面的应用潜力。这项工作为小麦霜霉病的特征气体检测提供了一个方向,也为利用 SPPS 沉积 LaFeO3 涂层提供了一个成功案例。
