中文摘要
摩擦纳米发电机（TENG）作为气体传感器是一种无需外部电源的检测策略。本研究制备了Ag/Bi2WO6复合材料，并将其用作TENG器件中的摩擦电层。引入Ag颗粒显著提升了器件的输出性能。此外，基于2% Ag/Bi2WO6的自供电气体传感器（SPGS）对100 ppm乙醇表现出27.6%的响应值，响应时间和恢复时间分别为72.7秒和81秒。该传感器还具有较低的检测限（LOD），可达2.7 ppm。其气体敏感性能的提升归因于Ag的催化作用，该作用促进了乙醇气体分子的吸附与脱附过程。本工作展示了多元金属氧化物在乙醇检测中的潜在应用价值。
English Abstract
Triboelectric nanogenerators (TENG) as gas sensor is a strategy for detection that does not require power source. This study prepared Ag/Bi 2 WO 6 composite as a triboelectric layer in a TENG device. Incorporating Ag particles improved output performance. Additionally, self-powered gas sensor (SPGS) based on 2% Ag/Bi 2 WO 6 exhibited a response of 27.6% to 100 ppm ethanol with response/recovery times (72.7/81 s). SPGS also have a lower limit of detection (LOD) as 2.7 ppm. The enhanced gas-sensitive performance to the catalytic effect of Ag, which facilitated the adsorption and desorption of ethanol gas molecules. This work demonstrating the potential application of multi-element metal oxides in ethanol detection was demonstrated.
