Abstract: Centered on “unveiling the magical potential of titanium”, this experiment commenced by employing electrochemical anodization to craft vibrant titanium oxide (TiO2) films. By meticulously adjusting applied voltages, electrolytes, and anodization durations, we achieved precise control over the coloration of these films, showcasing the captivating visual allure of chemistry. Subsequent X-ray photoelectron spectroscopy elucidated the composition of these intriguing layers, confirming their pure and non-toxic nature as titanium dioxide. Detailed discussions ensued regarding the refinement of oxide film quality processes and the adoption of environmentally friendly cycling techniques. Furthermore, we explored the application of anodized TiO2 films in dye wastewater treatment and NaCl corrosion resistance tests, unveiling their multifaceted capabilities encompassing degradation, antibacterial properties, and corrosion resistance. This endeavor underscores the beauty of applied chemistry. Finally, we devised a multifaceted science popularization plan aimed at disseminating knowledge to audiences of diverse backgrounds, dispelling concerns regarding the safety of titanium-colored film layers, and enabling participants to fully appreciate the enchantment of chemistry.
