Hollow Urchin-Like Ag-Doped In2O3 Nanomaterials for Enhanced Low-Temperature Methanol Sensing Under UV Irradiations
Source abstract
Abstract
Methanol gas sensors have great significance in the field of automotive fuel. It will be flammable, explosive, and highly toxic once there are excessive concentrations of methanol in the environment. Therefore, it is significantly important to investigate high-performance methanol sensors at a low working temperature. However, detecting methanol still faces great challenges such as low response value and high working temperatures due to the deficiency of active adsorption sites and high reaction barrier. In this work, hollow urchin-like Ag-doped In 2 O 3 nanomaterial is designed to fabricate highly sensitive photoelectrical methanol gas sensors. The hollow urchin-like Ag-doped In 2 O 3 nanomaterial exhibits excellent methanol-sensing performance with illumination of UV light, including low working temperature (100 °C), high response (80@50 ppm), and rapid response-recovery dynamic (12/35 s).
