The detection and portable monitoring of organic amine is necessary for hazardous substance warning, life, health. Herein, capsule-like tungsten oxide nanoparticles (NPs) were prepared to detect triethylamine, the gas-sensing property further enhanced by adjusting oxygen vacancy band structure doping with Ag NPs. As-prepared nanomaterial consists well-dispersed shapes. More chemically adsorbed are formed in Ag-doped oxide, bandgap decreases compared pristine oxide. tests show that optimal (Ag/WO3) NPs-based sensor exhibits more than six times response higher toward 50 ppm triethylamine (TEA) at an temperature 220 °C, a limit as low 248 ppb. Notably, fast recovery time anti-interference properties remarkable, two-week stability also satisfactory, which superior reported related materials. For real-time TEA detection, as-prepared Ag/WO3 proved be efficient sensing material applications.
