Abstract
A sonochemical co-precipitation method was employed to synthesize the CoO-ZnO nanocomposite for the degradation of methyl red (MR) anionic dye. The nanocomposite was characterized using UV–Vis spectrophotometer, FTIR, XRD, SEM-EDX, TGA and Zeta potential. The SEM images showed the agglomeration of spherical grains due to the difference in the magnetic nature of the sample. The zeta potential values exhibited that the colloidal suspension was present all over the surface. Response Surface Methodology (RSM) was utilized to optimize the degradation of MR dye, and achieved 89 % removal efficiency with a 30 mg dose of the catalyst over 120 minutes. The degradation mechanism relies on the photocatalytic activity of the synthesized CoO-ZnO nanocomposite, which generates reactive oxygen species to break down MR dye. The high degradation efficiency, achieved via RSM optimization, underscores the nanocomposite’s potential for environmental remediation. This makes it a promising solution for removing MR dye and other anionic dyes from polluted water.
期刊介绍:
The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
