Schottky barrier modulation via calcium hydroxide nanoparticles on g-C3N4/Ti3C2 for overall photocatalytic applications

Abstract

In this work, a novel 2D g-C3N4/Ca(OH)2/Ti3C2 heterojunction was synthesized via a one-step thermal method to enhance photocatalytic efficiency. With a 2.44 eV band gap and improved porosity, it enables stronger visible light absorption. Calcium hydroxide enhances structural integrity, while nitrogen vacancies optimize charge separation and Schottky barrier modulation. This photocatalyst achieves a CO evolution rate of 205.3 μmol g−1 h−1, H2 evolution of 17 300 μmol g−1 h−1, and 99.7% MB and 99.2% TC removal. This strategy advances sustainable energy and environmental remediation.
