Exploring the Mechanism of Photocatalytic Degradation using La2CrMnO6/g-C3N4 Nanocomposites: A Combined Experimental and Computational Study

Photocatalytic degradation has emerged as a promising approach for addressing environmental pollutants, with nanocomposite materials playing a crucial role in enhancing catalytic efficiency. This study explores the mechanism of photocatalytic degradation using La₂CrMnO₆/g-C₃N₄ nanocomposites through a combined experimental and computational approach. The La₂CrMnO₆/g-C₃N₄ heterostructure was synthesized and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV-Vis spectroscopy to assess its structural, morphological, and optical properties. Photocatalytic performance was evaluated under visible light irradiation, demonstrating enhanced degradation efficiency compared to individual components. Density functional theory (DFT) calculations were employed to investigate charge transfer dynamics, electronic band structure, and reaction pathways, providing insights into the synergistic interaction between La₂CrMnO₆ and g-C₃N₄. The findings highlight the role of interfacial charge separation and redox reactions in improving photocatalytic performance. This study advances the understanding of perovskitebased nanocomposites for environmental remediation and paves the way for the development of efficient photocatalytic materials.
