Butanol, a highly toxic volatile organic compound, poses significant health risks. Consequently, the creation of efficient gas-sensitive materials for butanol detection holds substantial practical significance. This study employed a secondary hydrothermal technique to synthesize InO, BiVO, and their composite InO/BiVO. Notably, the InO/BiVO composite exhibited a threefold enhanced response, short desorption time and low operating temperature compared to pure BiVO. Moreover, the composite demonstrated improved selectivity, certain moisture-proof performance, and prolonged stability. The synthesis strategy, which entailed growing microspherical InO on BiVO, led to structural modifications, enhanced surface area, increased oxygen adsorption capacity, an enlarged optical bandgap, and improved anti-interference ability of the device. As a result, the formation of an n-n heterojunction between InO and BiVO in the composite material translates into an outstanding butanol sensing device.
丁醇是一种剧毒挥发性有机化合物，会带来重大健康风险。因此，开发用于丁醇检测的高效气敏材料具有重要的实际意义。本研究采用二次水热技术合成了InO、BiVO及其复合材料InO/BiVO。值得注意的是，与纯BiVO相比，InO/BiVO复合材料的响应增强了三倍，具有较短的脱附时间和较低的工作温度。此外，该复合材料还表现出更好的选择性、一定的防潮性能和更长的稳定性。这种合成策略是在BiVO上生长微球形InO，导致结构改性、表面积增加、氧吸附能力增强、光学带隙增大以及器件抗干扰能力提高。结果，复合材料中InO和BiVO之间形成的n-n异质结造就了出色的丁醇传感装置。
