摘要

Graphitic carbon nitride (g-C₃N₄) is one of the most enticing ‘celebrities’ in photocatalysis due to its easily manufacturable nature, stable chemical properties, and suitable band structure. Here, we report the synthesis of a graphitic carbon nitride nanophotocatalyst (g-C₃N₄–RB) that is solar radiation-based and covalently bonded to a light-harvesting RB (RB) molecule (e.g., enhanced light absorption, improved charge separation). A highly effective nanophotocatalyst-based system was developed using g-C₃N₄–RB as the nanophotocatalyst. The attachment of RB enhances catalytic efficiency, making these nanomaterials a promising platform for future advancements in solar-driven photocatalysis and renewable energy applications. This system achieved notable NADPH regeneration (90.38%) and remarkable sulfide oxygenation efficiency (99%) and also facilitated solar-based photocatalysis, reducing dependence on traditional energy for chemical processes. The objective of the present research is to develop and utilize RB-based graphitic carbon nitride (g-C₃N₄) nanophotocatalysts for the direct synthesis of solar compounds and the oxygenation of sulfides under solar radiation. This novel approach enables an eco-friendly environment for pharmaceutical substrate production and promotes the utilization of solar energy for sustainable organic transformations.
