Sensing of heavy metal Pb²⁺ ions in water utilizing the photonic structure of highly controlled hexagonal TiON/TiO₂ nanotubes.

ABSTRACT: The detection of heavy metals in water, especially Pb²⁺ ions, is important due to their severe hazardous effects. To address this issue, a highly controlled hexagonal TiON/TiO₂ heterostructure has been synthesized in this study. The fabrication process involved the utilization of atomic layer deposition and direct current sputtering techniques to deposit TiO₂ and TiON layers onto a porous Al₂O₃ membrane used as a template. The resulting heterostructure exhibits a well-ordered hollow tube structure with a diameter of 345 nm and a length of 1.2 µm. The electrochemical sensing of Pb²⁺ ions in water is carried out using a cyclic voltammetry technique under both light and dark conditions. The concentration range for the Pb²⁺
