Two-dimensional SnS nanoflakes: synthesis and application to acetone and alcohol sensors

Abstract

SnS nanoflakes were synthesized using a solid state reaction method at 600 °C and their gas sensing properties were investigated.

Fast and selective detection of volatile organic compounds using a novel pseudo spin-ladder compound CaCu2O3

“…A detailed analysis of the reactions involved for acetone and ethanol has been previously reported. 39 In the schematic representation (Scheme 1) below are represented all the steps which were carried out for the resistance variation and, hence, for the sensor response:…”

Defect-Induced Gas-Sensing Properties of a Flexible SnS Sensor under UV Illumination at Room Temperature

“…However, the presence of S vacancies has been reported to impart n-type properties to SnS by some authors [ 12 , 13 ]. From the viewpoint of gas-sensing applications, p-type SnS sensors show the ability to detect toxic gases and volatile organic compounds (VOCs) at RT [ 6 , 14 ]. The disadvantage of p-type SnS sensors is their high base resistance, which hinders the ability to integrate them into portable and flexible devices.…”

Effect of Thioacetamide Concentration on the Preparation of Single-Phase SnS and SnS2 Thin Films for Optoelectronic Applications

“…Similarly, the favorable electronic characteristics, excellent structural flexibility, wider spectral response, and better thermal stability of SnS 2 make it a competitive nontoxic substitute for the conventional CdS [14] and Zn(O,S) [20] buffers in thin-film solar cells [2]. Furthermore, both SnS and SnS 2 have also been applied in photodetectors [21,22], photocatalysis [23], water splitting [24], gas sensors [25,26], biosensors [27], field-effect transistors [28,29], lithium-sodium ion batteries [30,31], thermoelectrics [32], electrochemical capacitors [33], and supercapacitors [34].…”
