What's Happening?
A recent study published in Nature investigates the photocatalytic oxidation of tyrosine using colloidal cadmium sulfide (CdS) particles under visible light irradiation. The research focuses on the characterization and behavior of these particles, which are synthesized using cadmium iodide as a precursor. The study employs various analytical techniques, including X-ray diffraction (XRD) and transmission electron microscopy (TEM), to determine the phase structure and size of the CdS particles. The photocatalytic process is monitored through UV-visible spectrophotometry, revealing the formation of dityrosine and dopachrome as oxidation products. The study highlights the role of hydroxyl radicals in facilitating the oxidation process, with experiments demonstrating the light-driven nature of the reaction.
