Schottky barrier modulation <i>via</i> calcium hydroxide nanoparticles on g-C<sub>3</sub>N<sub>4</sub>/Ti<sub>3</sub>C<sub>2</sub> for overall photocatalytic applications
In this work, a novel 2D g-C<sub>3</sub>N<sub>4</sub>/Ca(OH)<sub>2</sub>/Ti<sub>3</sub>C<sub>2</sub> heterojunction was synthesized <i>via</i> 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<sup>-1</sup> h<sup>-1</sup>, H<sub>2</sub> evolution of 17 300 μmol g<sup>-1</sup> h<sup>-1</sup>, and 99.7% MB and 99.2% TC removal. This strategy advances sustainable energy and environmental remediation.
