Facile two-step synthesis of yttrium-doped g-C₃N₄ for enhanced photocatalytic degradation of methylene blue with self-cleaning properties.

ABSTRACT: In this study, porous graphitic carbon nitride (g-C₃N₄) with different yttrium (Y) doping ratios are synthesized using a facile two-step pyrolysis method, yielding Y/g-C₃N₄-1, Y/g-C₃N₄-2, Y/g-C₃N₄-3, and Y/g-C₃N₄-4. These synthesized materials are used for the photocatalytic degradation of methylene blue (MB). Among the synthesized combinations, Y/g-C₃N₄-3 showed the highest photocatalytic activity (99%) under visible light. It exhibited pseudo-first-order kinetic behavior (k = 0.0439 min^-1, R ² = 0.999, t _1/2 = 15.78 min) for MB degradation, outperforming the other materials. In tap water, Y/g-C₃
