Catalytic remediation of water pollutants using Ag/ZnO nanocomposites stabilized with carboxymethyl cellulose: a kinetic investigation

Abstract Nowadays, polymers are acting as the foundation of advanced materials covering economically most of the world needs. These natural or synthetic polymers are converted into more innovative materials by integrating them with nanotechnology. This study presents an effective catalytic system comprising of carboxymethylcellulose (CMC)-stabilized Ag/ZnO nanocomposites (NCs) which were characterized using advanced techniques, including Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction and field emission scanning electron microscopy. These NCs’ were tested for their catalytic potential in degrading rhodamine-B, methyl orange, malachite green, and methylene blue. With quick removal rates and advantageous kinetics, these NCs showed outstanding degrading efficiency. Additionally, the catalyst’s reusability was also evaluated and the findings are presented in this research work. In a nut shell, CMC-stabilized Ag/ZnO NCs are not only effective catalysts but also lays the groundwork for further studies in catalysis. Graphical Abstract
