Polyvinyl alcohol assisted Fe2O3/NiO hyper cross-linked polymer as a photocatalytic signal damper to aromatic hydrocarbons
In this study, poly vinyl alcohol assisted Fe2O3/NiO hyper cross linked polymer (HCP) were synthesized via Sol-gel method were mainly focused to remove aromatic hydrocarbons, but it also exhibit the adsorption of organic pollutants making it versatile for environmental remediation. The X-ray diffraction analysis shows the formation Fe2O3/NiO composites. The morphological studies confirm the formation of hyper cross linked polymer in agglomerated state. Besides the Tauc plot depict the increase in the bandgap after the incorporation of NiO on Fe2O3 nanoparticles. Then the Fe2O3/NiO HCP composites were characterized using diesel oil as a typical adsorbate via batch adsorption-photocatalytic experiment in aqueous solution. It shows an effective adsorption of Methylene blue (84% in 80 min) and the diesel oil in aqueous solution with the maximum adsorption efficiency of 93% with the linear correlation coefficient of 0.9768 via photocatalytic UV light signal damper. Also the Fourier transform infrared spectra confirm the maximum adsorption occurs for Fe2O3/NiO HCP as composites. The TOC analysis shows highest reduction efficiency for Fe2O3/NiO HCP as 94.64% (Methylene blue dye), and 85.87% (Diesel sample). This work depict the adsorption of aromatic based compounds in the aqueous solution, since the composite is magnetic in nature it could be removed and recycled for the further use.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
