GENERATION HONEYCOMB-STRUCTURE OF TITANIA NANOTUBES AND THEIR CHARACTERIZATION

In this research, we highlight the honeycomb structure generated by electrochemical anodization and the effect of anodization voltage on the diameter and wall thickness of titania (TiO₂) nanotubes. According to our observations, a tiny change in the anodization parameter causes the morphology of nanotubes to vary. As a result, nanotube production is an extremely delicate process. Following the experimental section, we obtained nanotubes with diameters of 38, 55, and 91 nm and anodization potentials of 20, 30, and 40 V, respectively. With constant time, temperature, and pH, nanotubes grew and became longer at 20 V. Such morphology significantly impacts titania nanotube applications like photocatalysis for wastewater treatment.
