ABSTRACT
Significance of the Study:
This study highlights the sustainable valorization of dead pine needles into biochar-based composites (Biochar/CuO and Biochar/CuO/BaO) for environmental and biomedical applications. The composites exhibit enhanced photocatalytic dye degradation (98.8% efficiency) and potent antibacterial activity against Enterococcus faecalis, leveraging biochar’s porosity and metal oxides’ semiconductor properties. By converting forest waste into functional nanomaterials, this research promotes eco-friendly wastewater treatment and microbial control, supporting circular economy principles and reducing biomass pollution.
Summary of the Study:
The study synthesized Biochar/CuO and Biochar/CuO/BaO composites from pine needle-derived biochar via pyrolysis. Characterization confirmed crystalline integration, reduced bandgap, and improved surface properties. The composites demonstrated exceptional photocatalytic degradation of methylene blue (98.8%) and strong antibacterial effects against E. faecalis. The synergistic effects of biochar and metal oxides enhance performance, offering a sustainable solution for water remediation and biomedical applications while repurposing forest waste into value-added materials.
