Abstract

This study demonstrates direct fabrication of a visible-light-responsive LaTiO₂N film via nitridation of the La₂Ti₂O₇ film hydrothermally prepared on a titanium substrate as an oxide precursor. The thickness and surface morphology of the film were not significantly affected by nitridation. An anodic photocurrent was observed for the LaTiO₂N film fabricated using colloidal IrO₂ as a cocatalyst for the oxidation of water, indicating the oxidation of water. This implies that the fabricated LaTiO₂N film functions as an n-type semiconductor electrode under visible-light irradiation.
