SnS<sub<2</sub< Nanosheets as a Template for 2D SnO<sub<2</sub< Sensitive Material: Nanostructure and Surface Composition Effects

Two-dimensional nanosheets of semiconductor metal oxides are considered as promising for use in gas sensors, because of the combination of a large surface-area, high thermal stability and high sensitivity, due to the chemisorption mechanism of gas detection. In this work, 2D SnO<sub<2</sub&...

520			\|a Two-dimensional nanosheets of semiconductor metal oxides are considered as promising for use in gas sensors, because of the combination of a large surface-area, high thermal stability and high sensitivity, due to the chemisorption mechanism of gas detection. In this work, 2D SnO<sub<2</sub< nanosheets were synthesized via the oxidation of template SnS<sub<2</sub< nanosheets obtained by surfactant-assisted one-pot solution synthesis. The 2D SnO<sub<2</sub< was characterized using transmission and scanning electron microscopy (TEM, SEM), X-ray diffraction (XRD), low-temperature nitrogen adsorption, X-ray photoelectron spectroscopy (XPS) and IR spectroscopy. The sensor characteristics were studied when detecting model gases CO and NH<sub<3</sub< in dry (RH<sub<25</sub< = 0%) and humid (RH<sub<25</sub< = 30%) air. The combination of high specific-surface-area and increased surface acidity caused by the presence of residual sulfate anions provides a high 2D SnO<sub<2</sub< sensor’s signal towards NH<sub<3</sub< at a low temperature of 200 °C in dry air, but at the same time causes an inversion of the sensor response when detecting NH<sub<3</sub< in a humid atmosphere. To reveal the processes responsible for sensor-response inversion, the interaction of 2D SnO<sub<2</sub< with ammonia was investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) in dry and humid air at temperatures corresponding to the maximum “positive” and maximum “negative” sensor response.

In this work, 2D SnO<sub<2</sub< nanosheets were synthesized via the oxidation of template SnS<sub<2</sub< nanosheets obtained by surfactant-assisted one-pot solution synthesis. The 2D SnO<sub<2</sub< was characterized using transmission and scanning electron microscopy (TEM, SEM), X-ray diffraction (XRD), low-temperature nitrogen adsorption, X-ray photoelectron spectroscopy (XPS) and IR spectroscopy. The sensor characteristics were studied when detecting model gases CO and NH<sub<3</sub< in dry (RH<sub<25</sub< = 0%) and humid (RH<sub<25</sub< = 30%) air. The combination of high specific-surface-area and increased surface acidity caused by the presence of residual sulfate anions provides a high 2D SnO<sub<2</sub< sensor’s signal towards NH<sub<3</sub< at a low temperature of 200 °C in dry air, but at the same time causes an inversion of the sensor response when detecting NH<sub<3</sub< in a humid atmosphere. To reveal the processes responsible for sensor-response inversion, the interaction of 2D SnO<sub<2</sub< with ammonia was investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) in dry and humid air at temperatures corresponding to the maximum “positive” and maximum “negative” sensor response. 2D nanomaterials template synthesis SnS<sub<2</sub< nanosheets SnO<sub<2</sub< nanosheets gas sensor carbon monoxide Technology T Electrical engineering.

abstract	Two-dimensional nanosheets of semiconductor metal oxides are considered as promising for use in gas sensors, because of the combination of a large surface-area, high thermal stability and high sensitivity, due to the chemisorption mechanism of gas detection. In this work, 2D SnO<sub<2</sub< nanosheets were synthesized via the oxidation of template SnS<sub<2</sub< nanosheets obtained by surfactant-assisted one-pot solution synthesis. The 2D SnO<sub<2</sub< was characterized using transmission and scanning electron microscopy (TEM, SEM), X-ray diffraction (XRD), low-temperature nitrogen adsorption, X-ray photoelectron spectroscopy (XPS) and IR spectroscopy. The sensor characteristics were studied when detecting model gases CO and NH<sub<3</sub< in dry (RH<sub<25</sub< = 0%) and humid (RH<sub<25</sub< = 30%) air. The combination of high specific-surface-area and increased surface acidity caused by the presence of residual sulfate anions provides a high 2D SnO<sub<2</sub< sensor’s signal towards NH<sub<3</sub< at a low temperature of 200 °C in dry air, but at the same time causes an inversion of the sensor response when detecting NH<sub<3</sub< in a humid atmosphere. To reveal the processes responsible for sensor-response inversion, the interaction of 2D SnO<sub<2</sub< with ammonia was investigated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) in dry and humid air at temperatures corresponding to the maximum “positive” and maximum “negative” sensor response.
