Recently, several transition metal chalcogenide materials with favorable optical and electrical properties suitable for sustainable solar-based energy generation have been identified. In this work, thin films of two promising ternary sulfides (bornite and chalcopyrite) in the Cu–Fe–S system were successfully synthesized as thin films from utilizing tris-N,N-diethyldithiocarbamate iron(III) and bis-N,N-diethyldithiocarbamate copper(II) molecular precursors in aerosol-assisted chemical vapor deposition at 450 °C for 1 h. The deposited thin films were studied by powder X-ray diffraction, and the resulting patterns were indexed to orthorhombic and tetragonal copper iron sulfide (bornite, Cu5FeS4 and chalcopyrite, CuFeS2). The morphology of the films at the microscale was explored by scanning electron microscopy, revealing a polycrystalline thin film with elemental ratios (i.e., Cu:Fe:S) of the two materials corresponding to those expected for bornite (≈5:1:4) and chalcopyrite (≈1:1:2), consistent with the X-ray structural characterization. Characterization of the electrical transport properties of these high-quality thin films by the four-point probe method was performed. The results revealed resistivities of 1.8 × 10–4 Ω·m for bornite and 1.6 × 10–2 Ω·m for chalcopyrite, which are consistent with previously reported values for the bulk materials. Estimation of the optical energy band gap from Tauc plots of the ultraviolet-visible spectroscopy data was taken for bornite and chalcopyrite giving direct band gap energies of 1.28 and 0.97/1.62 eV, respectively, demonstrating their potential utility as either solar absorbing thin films or for photocatalysts for water splitting.

Chemical vapor deposition (CVD) is a widely used method for the synthesis of high-quality thin films of inorganic materials. Transition metal dichalcogenides (TMDs) have received a great deal of interest due to their electronic and catalytic properties. To enable the widespread use of CVD in the synthesis of TMDs for practical applications, the choice of precursor(s) is critical. Single-source precursors are appealing for CVD applications, as they can influence the properties of the deposited film, potentially simplify CVD processes, and reduce the use of hazardous coreactants such as H 2 S. In this Perspective, we discuss examples of single-source precursors that have been demonstrated to deposit group 4−6 sulfur or selenium TMDs via CVD, along with aspects of precursor design, decomposition mechanisms, and properties of the resulting materials.

Iron (III) diethyldithiocarbamate complex (Fe(DTC)) of the general formula [Fe(S2CN(Et)2)3] was synthesized and characterized using chemical, thermogravimetric (TGA/DTG), and (FT‐IR) analysis. The vapor adsorption tests verified that the Fe(DTC) was mesoporous and that the pore surface area was 16.73 m2/g, according to the N2 adsorption‐desorption isotherm. The main aim of this study is to eliminate methyl green (MG) from water via Fe(DTC) adsorption. The adsorption experiments, that investigated the influence of pH and mass, demonstrated that both of these factors have an impact on adsorption. The optimal conditions for MG adsorption onto the Fe(DTC) metal complex were 0.05 g for a Fe(DTC) mass and a pH value of 7 ± 0.2. At 333 K, the maximum capacity for the Fe(DTC) metal complex adsorbent was 26 mg/g for MG. At 180 min, the elimination efficiency for MG dye was approximately 87%. Based on the kinetic experiments, the pseudo‐second‐order model was determined to be the most appropriate for assessing the adsorption process. The mechanism of adsorption was studied by appropriating the adsorption data to the Temkin, Freundlich, Langmuir, Temkin, and Radushkevich models. The results can be adequately described by the Langmuir model.
