Semiconductor-based photocatalytic systems have found widespread use in environmental pollution cleanup and renewable energy production. In this study, we synthesized WO3 as a catalyst for the degradation of methylene blue, a thiazine dye, which was used in the previous work. The hydrothermal process is used to create WO3 nanoparticles, which are made from sodium tungstate. When it comes to confirming the nanoparticles, many characterization techniques are employed, including X-ray diffraction (XRD), Fourier transform infrared (FTIR), UV-Vis diffuse reflectance spectrometer (DRS), X-ray photoelectron spectroscopy (XPS), and field emission–scanning electron microscope (FE-SEM). The existence of monoclinic crystalline structure is shown by XRD, with the average crystalline size being around 34 nm. FTIR confirms the presence of metal oxides. The pellucid absorption extremity in the UV-Vis region corresponds to the rudimentary absorption of the WO3 semiconductor. FE-SEM confirms square-shaped nanoplates with EDX address the occurrence of elemental tungsten. The photocatalytic activity of WO3 nanoparticles against methylene blue is taken for at different intervals of time that confirms MB’s degradation. Our present work suggests that prepared nanoparticles should be potential for photocatalysts using various industrial dyes.

“…In recent years, metal oxide-carbon (MO-C) materials, due to their intriguing physical, chemical, electrical, and optical properties as well as their ability to combine multiple advantages and performance characteristics, have become one of the most important research topics. 1,2 Carbon materials with a large specific surface area and easy access to various pore sizes have attracted intense research, [3][4][5][6][7][8][9][10][11] although some deficiencies such as their low dispersibility in water make them undesirable for some applications. Metal oxide materials, also in spite of their versatile properties, possess some weak properties, such as low electrical conductivities, which restricts them in many applications.…”

The diverse applications of metal oxide-biopolymer matrix as a nanocomposite heterogenous catalyst have caused many researches to scrutinize the potential of this framework. In this study, a novel hybrid barium oxide-chitosan nanocomposite was synthesized through a facile and cost-effective co-precipitation method by doping barium oxide nanoparticles within the chitosan matrix at a weight percentage of 20 wt.% BaO-chitosan. A thin film of the novel hybrid material was produced by casting the nanocomposite solution in a petri dish. Several instrumental methods, including Fourier-transform infrared (FTIR), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD), were used to analyze and characterize the structure of the BaO-CS nanocomposite. The chemical interaction with barium oxide molecules resulted in a noticeable displacement of the most significant chitosan-specific peaks in the FTIR spectra. When the surface morphology of SEM graphs was analyzed, a dramatic morphological change in the chitosan surface was also discovered; this morphological change can be attributed to the surface adsorption of BaO molecules. Additionally, the patterns of the XRD demonstrated that the crystallinity of the material, chitosan, appears to be enhanced upon interaction with barium oxide molecules with the active sites, OH and NH2 groups, along the chitosan backbone. The prepared BaO-CS nanocomposite can be used successfully as an effective heterogenous recyclable catalyst for the reaction of N,N′-(alkane-diyl)bis(2-chloroacetamide) with 2-(arylidinehydrazine)-1-carbothioamide as a novel synthetic approach to prepare 2-hydrazonothiazol-4(5H)-ones. This new method provides a number of benefits, including quick and permissive reaction conditions, better reaction yields, and sustainable catalysts for multiple uses.
