“…The results of the XRD structural characterization of the synthesized material confirmed the presence of a kesterite-type crystalline phase, with a defined tetragonal geometry, and an I-42m space group with a preferential orientation in the crystallographic plane (2 2 0), showing concordance with ICSD collection code: 96-210-5814. Based on the main diffraction signals, it was possible to calculate the crystallite size using the Debye-Scherrer equation, obtaining an average value of 5.46 nm as a result, allowing it to be classified as a nanometric material in accordance with Lin, S. J. et al (6).…”

This article presents the synthesis of a kesterite phase quaternary semiconductor, based on the Cu2ZnSnS4 system (abbreviated CZTS), making use of a hydrothermal route starting from metal salt solutions. The results of characterization by X-ray diffraction (XRD) confirm the presence of a tetragonal kesterite phase I-42m with a preferential orientation in the plane (1 1 2). The results of the morphological characterization by means of scanning and transmission electron microscopy (SEM-TEM) confirmed the obtaining of nanometric particles, which are grouped as clusters of approximately 1 micron with crystallite sizes of ≈ 6.0 nm. The complementary analysis of electron microscopy with X-ray energy dispersion spectrometry (EDS) confirmed a good agreement in composition without evidence of volatilization of the species, which allowed the characteristics of the material to be preserved. The results of the analysis by ultraviolet (UV) spectroscopy determined the obtaining of a semiconductor with a band-gap of 1.46 eV, obtained by analyzing its absorption spectrum and the TAUC equation. The electrical properties of the material evaluated by solid state impedance spectroscopy confirmed that the synthesis route is appropriate for obtaining a semiconductor.

“…The process parameters such as usage of initial precursors (and their concentration), surfactant /complexing agent, pH value, and reaction temperature/time are controlling a phase purity, chemical composition, and morphology over synthesized nanoparticles by hydrothermal process [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] . The change in pH value of CCTS precursor's solution before and after the addition of MEA is shown in Fig.…”

Herein, the physical properties such as crystal phase, morphology, and chemical composition for Cu 2 CoSnS 4 (CCTS) nanoparticles, synthesized by hydrothermal growth at 200 °C, are studied according to the short reaction times from 1 h to 6 h, respectively. The raw data of chemical composition, XPS analysis, and their electrical properties of CCTS nanoparticles prepared at 200 °C for 12 h with different Cu concentrations are presented [1] in the present manuscript. Materials properties of CCTS and their electrical, optical properties were systematically studied, and their correlation between physical properties and materials properties is strongly studied in depth mode.

“…The CZTS has developed into a perfect absorber for thin-film-based photovoltaic applications because of its exceptional qualities, including earth-abundant and non-toxic materials, an ideal optical bandgap (1.0-1.5 eV), excellent absorption coefficients (>10 4 cm -1 ), and good electrical properties [14,15]. Additionally, Cu, Zn, Sn, and S are common in the crust and are essentially non-toxic, making the constituent elements of Cu2ZnSnS4 numerous in sources and environmentally friendly [16,17]. Cu2ZnSnS4 can be prepared in a variety of ways, and it has received more comprehensive research due to its chemical stability [18,19].…”

Industrial dyes contained a wide range of organic compounds that could affect the environment and high dimensional challenges to humans. In recent years, the environmentally safe and inexpensive quaternary copper-based chalcogenide Cu2ZnSnS4 (CZTS) has emerged as a material for photovoltaics and photocatalysis. CZTS nanoparticles were prepared in this investigation using the hydrothermal route at 210 °C for 24 h without the addition of a surfactant or capping agents. Rhodamine B (RhB), a carcinogenic dye, was degraded using the synthesized material through a photocatalytic process. The structural, morphological, optical, and photocatalytic characteristics of CZTS nanoparticles were examined using X-ray diffraction (XRD), Raman spectroscopy, Field emission scanning electron microscopy (FE-SEM), and UV-vis spectroscopy. The average particle size of CZTS is found to be 31 nm with crystalline nature have been characterized by XRD. The results demonstrate that the synthesized sample has mixed morphological structures such as clew-like and flower-like structures and a bandgap of 1.50 eV. CZTS nanoparticles were used as photocatalysts under direct sunlight for Rhodamine B degradation, with the fastest degradation efficiency of 72% at 50 minutes. The results show that surfactant-free hydrothermally synthesized CZTS nanoparticles are a very promising material for the degradation of RhB dye due to the rapid degradation rate and high degradation efficiency.
