Electrodeposition of CoNi alloys in a biocompatible DES and its suitability for activating the formation of sulfate radicals

• Electrodeposition of CoNi alloys in a biocompatible DES. Electrochemical parameters allowed fine control catalyst film morphology. exhibited efficient catalytic mineralization antibiotics. Building sustainable future requires new, accessible, economic, and ecological methods preparing nanostructured materials used biomedical environmental applications. In this work, detailed study on the electrodeposition process deep eutectic solvent (DES) is presented. Alloy plating performed choline chloride within urea-based DES us to tailor elemental compositions, morphologies, size deposits based conditions. Homogeneous, continuous, needle-shaped were characterized using electrochemical ex-situ characterization techniques. Although process's behavior corresponded that normal deposition, applying most negative potentials produced co-reduction solvent, which favored incorporation oxygen species into deposit. Given materials’ nature, morphology, composition tailored high active surface, tested as platforms activate formation sulfate radicals from peroxomonosulfate salt. Results related proposed material preparation method promising, as, confirmed by effectiveness degrading antibiotic tetracycline. Altogether, work showcases versatile, environmentally friendly route for electrodepositing DESs yield proactive tool developing with potential.
