Silver oxide (Ag₂O) has been extensively researched due to its strong redox behavior, antibacterial, and catalytic capabilities, photo degradation, agglomeration, and low reusability limit in its practical performance. Polyaniline (PANI) improves surface functionality, stability, and charge separation in Ag₂O structures, which improves photocatalytic and antibacterial performance. The structural, optical, characteristics that control these qualities are clarified through characterization utilizing UV, FTIR, XRD. Methylene blue dye was used to measure the photo catalytic activity of Ag₂O and PANI-Ag₂O nanocomposites, and their antibacterial potential was examined against bacterial and fungal pathogens. Overall, the study demonstrates that PANI-Ag₂O on composites exhibit superior multifunctional capabilities, making them promising materials for wastewater treatment and biomedical applications.
