Case Study

Conductivity Gas Sensors Based on Tin (IV) Sulfide Nanorods

Giberti, Alessio, et al. Sensors and Actuators B: Chemical, 2016, 223, 827-833.

The conductivity gas sensors based on synthetic nano-tin disulfide (SnS2) films were prepared by screen printing technology and their sensing performance for aldehydes, ketones and other gaseous compounds was tested. The findings indicate that at an operating temperature of 300 °C, the SnS2 film demonstrates a significant selectivity for the carbonyl functional groups present in aldehydes and ketones.
Synthesis of SnS2 and deposition of thin films
· First, 2.3 mmol of SnCl4·5H2O were dissolved in 2 mL of HCl (37% m/v). Subsequently, 30 mL of distilled water were added to the resulting suspension, and the solution of Sn4+ ions was stirred for 10 minutes. Afterward, 3.3 mmol of thioacetamide and 18 mL of water were added. The mixture was stirred for 3 hours, resulting in the formation of a brown precipitate of SnS2. The control of S2- ions' concentration was achieved by maintaining an acidic environment, which allowed the control of the growth of the SnS2 crystallites. The precipitate was then isolated by vacuum filtration, washed with water and methanol, and dried for 6 hours at 40 °C in air.
· Next, the sensing paste was prepared by adding organic vehicles to the SnS2 powder, followed by its deposition on the alumina substrate using a screen-printing technique, resulting in a film thickness of about 30 μm. Subsequently, the screen-printed films underwent thermal stabilization at 180 °C in a muffle oven for 12 hours in air to allow the evaporation of organic vehicles. Finally, the substrate was mounted on a suitable support to be interfaced with the electronic measuring system.

SnS2 Nanosheets for High-Performance Photocatalytic Hydrogen Production

Yu, Jing, et al. ACS applied materials & interfaces, 2014, 6(24), 22370-22377.

Monodisperse tin disulfide (SnS2) nanosheets (diameter of about 0.8-1 μm and thickness of about 22 nm) were successfully prepared by a simple solvothermal procedure. Experiments showed that the SnS2 nanosheets (SnS2 NSs) exhibited high photocatalytic hydrogen production activity (1.06 mmol h-1 g-1) under simulated sunlight irradiation, and also exhibited excellent photoelectrochemical response performance in the visible light region.
Preparation of SnS2 NSs and characterization of photocatalytic activity
· Synthesis of SnS2 NSs: 1 mmol of SnCl2·2H2O, 2 mmol of thioacetamide (TAA), and 0.5 g of PVP were combined in 30 mL of triethylene glycol (TEG) while stirring vigorously at room temperature. The resulting clear solution was then transferred to a 50 mL Teflon-lined stainless steel autoclave, where it was heated to 220 °C for 12 hours before cooling to room temperature naturally. The product obtained was centrifuged at 10,000 rpm for 8 minutes and washed multiple times with ethanol. Ultimately, the yellow SnS2 powder was collected after being dried overnight at 60 °C.
· Photocatalytic activity of SnS2 NSs: The photocatalytic generation of hydrogen from water was performed using the CEL-SPH2N photocatalytic activity evaluation system. In a typical experiment, 20 mg of catalyst powder was added to 100 mL of a 10 vol % methanol solution, along with 0.1 M Na2S and 0.1 M Na2SO3 as sacrificial agents. Prior to starting the catalytic reaction, the entire system was evacuated with a mechanical pump. The amount of hydrogen produced was determined based on a fitted standard curve.
