摘　　要：氨气检测涉及各种行业,可用于环境分析、空调压缩机、呼吸诊断分析、化肥工业等。氨气是环境和安全监测重点关注的对象,其相应的传感器显得尤为重要。目前,传统的氨气传感器检测速度已经得到一定的提升,但仍存在工作温度过高等不足,制备室温下快速检测氨气的传感器尤为必要。文章采用液相激光烧蚀的方法合成高氧空位的微纳米三氧化钨材料,用于高效的室温氨气传感器。该制备方法具有可控性好、纯度高、生产效率高和装置简单等优点,所获得的三氧化钨材料在室温下对氨气的响应度达到56%,优于同类型传感器的性能,有望应用于制作高性能的室温氨气传感器。Ammonia(NH_(3))detection plays a crucial role in various fields,including environmental analysis,air conditioning compressors,respiratory diagnostics,and the fertilizer industry.As a key concern in environmental and safety monitoring,its corresponding sensors are particularly important.Although traditional NH_(3) sensors have seen improvements in detection speed,there are limitations to their functions such as high operating temperatures.This underscores the necessity to develop sensors capable of rapidly detecting NH_(3) at room temperature.This study employs a liquid-phase laser ablation method to synthesize micro-nano tungsten trioxide(WO_(3))materials with high oxygen vacancies for highly efficient room-temperature NH_(3) sensors.The preparation method demonstrates advantages such as excellent controllability,high purity,high production efficiency,and simple equipment requirements.The synthesized WO_(3)material achieves a 56%response to NH_(3) at room temperature,outperforming similar sensors,showing promising potential for developing high-performance room-temperature NH_(3) sensors.
