In Situ Fabrication of SnS2/SnO2 Heterostructures for Boosting Formaldehyde−Sensing Properties at Room Temperature

Nanomaterials, Год журнала: 2023, Номер 13(17), С. 2493 - 2493

Опубликована: Сен. 4, 2023

Formaldehyde, as a harmful gas produced by materials used for decorative purposes, has serious impact on human health, and is also the focus difficulty of indoor environmental polution prevention; hence, designing developing sensors selective measurement formaldehyde at room temperature an urgent task. Herein, series SnS2/SnO2 composites with hollow spherical structures were prepared facile hydrothermal approach purpose sensing temperature. These novel hierarchical structured composites−based demonstrate remarkable selectivity towards within concentration range sub-ppm (0.1 ppm) to ppm (10 Notably, SnS2/SnO2−2 sensor exhibits exceptional formaldehyde-sensing performance, featuring ultra-high response (1.93, 0.1 17.51, 10 ppm), well good repeatability, long-term stability, outstanding theoretical detection limit. The superior capabilities can be attributed multiple factors, including enhanced adsorption, larger specific surface area porosity structure, synergistic interfacial incorporation heterojunction. Overall, excellent performance spheres opened up new way their trace

Nanomaterials, Год журнала: 2025, Номер 15(2), С. 129 - 129

Опубликована: Янв. 16, 2025

The SnO2@Bi2O3 core-shell heterojunction structure was designed and synthesized via a hydrothermal method, the morphology of samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS). Based on conclusions from XRD SEM, it can be observed that as temperature increases, content Bi2O3 coated surface SnO2 spheres gradually diameter nanoparticles also increases. At 160 °C, are fully with nanoparticles. This paper investigated gas-sensitive performance sensor towards ethanol gas. Gas sensitivity tests at optimal operating 300 °C showed composite prepared achieved response value 19.7 for 100 ppm ethanol. Additionally, exhibited excellent to ethanol, time only 4 s, well good repeatability. gas is attributed its p-n material properties. Its successful preparation contributes realization high-performance heterostructure sensors.
