Major Contributions

1. Development of a novel photocatalyst by incorporating ruthenium into g-C3N4, which achieved significant LDPE degradation of up to 74.51 wt% within 24 hours under optimal conditions, demonstrating superior efficiency compared to existing methods.

2. Identification of optimal degradation conditions through systematic investigation of pH and temperature effects, revealing peak performance at pH 3 and 50°C, providing crucial operational parameters for practical applications.

3. Elucidation of the degradation mechanism involving Norrish Type I and II reactions, where Ru-gCN facilitates electron transfer and radical formation, leading to enhanced photocatalytic activity and efficient plastic decomposition.
