Summary Metal sulfides conjugated graphene oxide (GO) have captivated researchers owing to the elaborated opto‐electrochemical and photocatalytic properties. Current research reports the synthesis of Copper sulfide (CuS) and cadmium sulfide (CdS) bimetal sulfide GO composite by single‐source precursor using diethyl dithiocarbamate ligand. The synthesized alloy was deposited through electron beam deposition system. Characterization of the thin films was done by various techniques including, XRD, UV‐visible spectrophotometry, fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM)‐energy dispersive X‐ray analysis (EDX). Electrochemical properties were investigated through cyclic voltammetry and linear sweep voltammetry using 3‐M KOH. Degradation of toxicants such as methyl red dye, pesticide isopyrazam, and phenol was done by the thin film to evaluate its photocatalytic characteristic. (CuS‐CdS)GO thin film showed separate bandgaps for CuS and CdS as 2.04 and 3.3 eV. A hexagonal crystal system for (Cu2S‐CdS)GO was observed through XRD with an average crystal size of 50 nm. A cubic shape with globular edges was detected by SEM investigation. An impressive specific capacitance value of 35 F g−1 at 100 mV s−1 proved it as a promising electrode for supercapacitors. A remarkable photocatalytic degradation rate was obtained by the thin film for all the toxicants with the highest rate for pesticide, that is, 81% under just 60 minutes, which remained >70% even after four successive cycles. The profound electrochemical and photocatalytic properties of (Cu2S‐CdS)GO thin film make it an auspicious material for optical, electrical, and photo‐devices.

The present work outlines the synthesis of e-beam deposited (Sn2Sb2S5)GO:FTO thin film. The surface and physicochemical characterization of the thinfilm was done through X-ray diffraction (XRD), X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray and UV-visible spectrophotometry. An orthorhombic phased Sn2Sb2S5-GO was confirmed by XRD with crystallite size of 16.9 nm. SEM morphology revealed homogenous distribution of grains and sheet-like structure of graphene oxide (GO) and a direct band gap of 2.9 eV. Moreover, electrical investigation presented (Sn2Sb2S5)GO:FTO as an excellent electrode material with 303 F g−1 specific capacitance. The photocatalytic degradation rates by the thinfilm for methyl red dye, pesticide and phenol were 70%, 94% and 54%. The dynamic properties of the investigated film present it as a propitious material for opto-electrical and remediation devices.

“…When manufacturing various devices, it is often necessary to form SnO 2 -based films. As a rule, such classical methods as dip-coating [28,29], spin-coating [30,31], physical vapor deposition (PVD) [32] and chemical vapor deposition (CVD) [26,33] are used for this purpose. These methods have some disadvantages, including limitations on the accuracy of dosing and targeting upon deposition of the material on the substrate surface, the risk of a gradient across the film thickness, high energy costs and precursor consumption, poor reproducibility, etc.…”

The atmospheric pressure solvothermal (APS) synthesis of nanocrystalline SnO2 (average size of coherent scattering regions (CSR)—7.5 ± 0.6 nm) using tin acetylacetonate as a precursor was studied. The resulting nanopowder was used as a functional ink component in microextrusion printing of a tin dioxide thick film on the surface of a Pt/Al2O3/Pt chip. Synchronous thermal analysis shows that the resulting semiproduct is transformed completely into tin dioxide nanopowder at 400 °C within 1 h. The SnO2 powder and the resulting film were shown to have a cassiterite-type structure according to X-ray diffraction analysis, and IR spectroscopy was used to establish the set of functional groups in the material composition. The microstructural features of the tin dioxide powder were analyzed using scanning (SEM) and transmission (TEM) electron microscopy: the average size of the oxide powder particles was 8.2 ± 0.7 nm. Various atomic force microscopy (AFM) techniques were employed to investigate the topography of the oxide film and to build maps of surface capacitance and potential distribution. The temperature dependence of the electrical conductivity of the printed SnO2 film was studied using impedance spectroscopy. The chemosensory properties of the formed material when detecting H2, CO, NH3, C6H6, C3H6O and C2H5OH, including at varying humidity, were also examined. It was demonstrated that the obtained SnO2 film has an increased sensitivity (the sensory response value was 1.4–63.5) and selectivity for detection of 4–100 ppm C2H5OH at an operating temperature of 200 °C.
