| description | <p></p><div> <p>In this study, the application of the core-shell Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub> nano-catalysts for fenton-like degradation of malachite green dye has been presented. The nano-catalysts were prepared using a combination of solvothermal and sol-gel techniques and characterized using XRD, FTIR, SEM/EDX, TEM and VSM techniques. The effects of various reaction parameters on the degradation of malachite green dye using the prepared nano-catalysts were investigated. The optimal condition for pH, catalyst dosage and H<sub>2</sub>O<sub>2</sub> amount were found to be at 6.7, 15 mg and 50 μL, respectively. Under the optimized conditions, a degradation efficiency of 96.18 % for malachite green dye was achieved using the catalyst within 30 minutes at 303 K with a pseudo first order rate constant of 0.1102 min<sup>−1</sup>. The plausible mechanism for MG degradation was determined to be the combination of adsorption and simultaneous decomposition via formation of hydroxyl radicals. The performance of the nano-catalyst was compared with other fenton-like catalysts reported in the literature. Finally, the magnetic properties of the Fe<sub>3</sub>O<sub>4</sub>@SiO<sub>2</sub> catalysts was utilized for its successful recovery and application in multiple degradation cycles.</p> </div><p></p><h2>Other Information</h2> <p> Published in: ChemistrySelect<br> License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="http://dx.doi.org/10.1002/slct.202003937" target="_blank">http://dx.doi.org/10.1002/slct.202003937</a></p> |
