Gold-loaded tungsten trioxide nanofiber, preparation method and gas sensor
By preparing dendriticized gold-loaded tungsten trioxide nanofibers as gas-sensitive materials, the problems of slow response, poor selectivity, and poor stability of existing sensors for the detection of diethyl carbonate were solved, achieving high sensitivity and long-term stable detection results.

Abstract
This invention discloses a gold-loaded tungsten trioxide nanofiber, its preparation method, and a gas sensor. The gold-loaded tungsten trioxide nanofiber comprises dendritic WO3 nanofibers and Au nanoparticles loaded on the surface of the dendritic WO3 nanofibers. The nanofibers of this invention have a dendritic surface modified with a large number of Au particles. When used as a gas-sensitive material in a gas sensor, it exhibits highly sensitive and rapid response characteristics to diethyl carbonate, enabling highly selective, highly sensitive, and long-term stable detection of diethyl carbonate.
