چکیده انگلیسی
The pure and W-doped MoO3 nanobelts were prepared via a facile one-step hydrothermal method. The morphology and microstructure of the developed nanobelts were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). The characterization results showed that as-prepared samples are uniform nanobelts with a mean length of 20 µm and width range of 100-200 nm, and W element was distributed uniformly in MoO3 nanobelts. The comparison between pure and doped samples was carried out to reveal the superior gas sensing performance of W-doped MoO3 nanobelts. The results of sensing properties indicate that the sensors based on W-doped MoO3 nanobelts exhibit high response, good selectivity, and long term stability characteristics towards trimethylamine (TMA) gas, which are promising for trimethylamine sensors used to monitor air-quality and environmental.
