Abstract
The scientific community has preferred the photocatalysis process to remove organic pollutants from water. Many catalysts have been developed over the years, and one such catalyst is molybdenum disulfide (MoS2), which is a two-dimensional (2D) material with an energy bandgap in the visible spectrum. In this manuscript, the facile synthesis of MoS2 nanostructures in varying molybdenum (Mo) and sulphur (S), Mo/S ratios has been demonstrated through a single-pot hydrothermal route. The structural validation of the nanostructures was done using X-ray diffraction (XRD) patterns. Further, the morphological information about the MoS2 nanostructures was gathered using the Field Emission Scanning Electron Microscope (FE-SEM) and High-Resolution Transmission Electron Microscope (HR-TEM) analyses. The photodegradation process of the Malachite Green dye was analyzed by UV-visible absorption spectroscopy. The results showed that 1T/2H MoS2 nanoflowers degraded the malachite green dye with a degradation efficiency of 98.4%. The decomposition of this commonly used dye possesses great significance in industrial waste water treatment.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
