摘要

摩擦纳米发电机作为气体传感器是一种不需要电源的检测策略。本研究在TENG装置中制备了Ag/Bi2WO6复合材料作为摩擦电层。加入银颗粒提高了输出性能。此外，基于2% Ag/Bi2WO6的自供电气体传感器（SPGS）对100 ppm乙醇的响应率为27.6%，响应/恢复时间为72.7/81 s，检测下限（LOD）为2.7 ppm。Ag的催化作用增强了气敏性能，有利于乙醇气体分子的吸附和解吸。这一工作证明了多元素金属氧化物在乙醇检测中的潜在应用。

Ag/Bi2WO6-based triboelectric nanogenerators for self-powered ethanol sensor

Triboelectric nanogenerators (TENG) as gas sensor is a strategy for detection that does not require power source. This study prepared Ag/Bi₂WO₆ 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/Bi₂WO₆ 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.
