Abstract

An efficient method for detecting H₂S gas at low temperatures using micrometer-sized spherical Ag₃PO₄-doped SnO₂ materials synthesized by hydrothermal and chemical precipitation methods is reported. The crystalline phase, defects, elemental composition, and morphology of the samples were characterized in detail using scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The characterization results verified the spherical structures of Ag₃PO₄-doped SnO₂ materials. The performance analysis revealed that the proposed gas sensor has the advantages of low operating temperature (100 °C), high response value (118), and good selectivity. The excellent H₂S gas sensing performance is attributed to the increased oxygen vacancy defects and facile electron transfer process in the conduction band. Overall, this study validates the potential of gas-sensitive sensors based on Ag₃PO₄-doped SnO₂ materials for practical applications.
