Description
Summary:In the pursuit of advancing novel photocatalytic solutions for removal methylene blue (MB) from aqueous environments, our investigation centered on harnessing the potential of red alga valorization. By employing meticulous characterization techniques, we observed a transformative conversion of powdered alga into calcium oxide, distinguished by intricately structured and uniformly porous qualities. Furthermore, the analysis of UV outcomes unveiled a remarkably narrow band gap energy (2.61 eV) within the photocatalyst. Notably, our catalytic system exhibited exceptional prowess in the solar-driven photodegradation of methylene blue, achieving a substantial degradation efficiency (96%) within a brief 20-min interval. Conclusively, this study has unveiled the latent potential of red alga as an auspicious foundation for pioneering the evolution of novel photocatalytic agents.
