    Abstract:
    This study investigates the co-precipitation synthesis of (2 and 4 wt%) Ag and polyacrylic acid-doped SrO nanocomposites for bactericidal activities and catalytic Rhodamine B (RhB) decolorization. The objective of the investigation was to minimize the rate of electron-hole recombination of SrO to enhance charge transfer. The influence of Ag and PAA on the crystal structure, morphology, absorbance wavelength, and exciton recombination rate of SrO was studied using a systematic characterization. The binary dopants were added into SrO to reduce the crystallite size, which produces the new active sites (reduces the recombination rate) and may generate reactive oxygen species (ROS). In a neutral medium with sodium borohydride (NaBH4), the synthesized nanocomposites demonstrated reasonable results for catalytic reduction of RhB dye (74.3 %). The bactericidal efficiency (96.6 %) of prepared samples was measured for Escherichia coli (E. coli) at various concentrations. Molecular docking studies were performed to rationale the antibacterial activity of PAA-SrO and Ag/PAA-SrO nanocomposites against DHFRE. coli, DHPSE. coli, and FabIE.coli suggested their role as inhibitors.
