"快速响应钯基氢传感器制备及应用于智慧交通物联网"

The document titled "物联网-智慧交通-AAO模板制备快速响应钯基氢传感器.pdf" focuses on the development of a rapid response hydrogen sensor for use in smart transportation systems within the Internet of Things (IoT) framework. The importance of such a sensor lies in the fact that hydrogen is an explosive gas, which can pose a serious safety risk if its concentration in the air falls within the range of 4.65% to 74% by volume. In the event of a hydrogen leak, a fast-responding sensor is crucial for detecting the gas quickly and providing ample time for people to evacuate to safety. The main objective of this research is to prepare a hydrogen sensor based on a palladium (Pd) catalyst with an anodic aluminum oxide (AAO) template. The AAO template is fabricated using a two-step anodic oxidation process, resulting in pores with an average size ranging from 70 to 80 nm. The distance between these pores is optimized to enhance the sensor's sensitivity and response time to hydrogen gas. Overall, the development of a fast-responding hydrogen sensor using AAO template preparation techniques represents a significant advancement in enhancing the safety and efficiency of smart transportation systems. By leveraging IoT technology, such sensors can play a crucial role in early detection and mitigation of potential hydrogen-related hazards, thereby safeguarding both the public and infrastructure from the risks associated with hydrogen gas leakage.
