• Cost-effective synthesis of silver nanoparticles using Crataegus pentagyna fruit extract is reports for the first time. • The CP -AgNPs was characterized using XRD, FT-IR, EDS, TEM, SEM, DLS and UV–Vis. • Spherical CP -AgNPs showed a high photocatalytic and antibacterial activities in the degradation of organic pollutants and various bacteria, respectively. • As-synthesized silver nanoparticles were used against multi-drug resistance gram negative and gram positive of bacteria. In this work, a cost-effective/green/high-efficient/facile process for the preparation of silver nanoparticles using C. pentagyna (CP -AgNPs) fruit extractas as reducing agent and capping agent was reported. The influence of different parameters including temperature, pH, concentration and time were studied to reach optimum conditions. The as-synthesized CP -AgNPs were characterized using UV/Vis, XRD, SEM, TEM, EDS and DLS analysis. Regular, spherical morphology and homogeneous of CP -AgNPs with a mean particles size of 25–45 nm was determined from TEM images. The CP -AgNPs in presence of sunlight catalyzed the degradation of the organic contaminant dyes, rhodmine b (RhB), eosin (EY) and methylene blue (MB) with percent degradation of 85% and 70% and 78%, respectively. In addition, CP -AgNPs exhibit antibacterial activities against seven ATCC strains of bacteria and eight strains of drug-resistant bacteria. Due to the results, CP -AgNPs enhanced antimicrobial potential against S. aureus, E. faecalis , P. aeruginosa , A. baumannii and E. coli with MIC and MBC of (0.11, 7.1 µg/ml), (0.11, 1.7 µg/ml), (0.11, 0.22 µg/ml), (0.11, 0.22) and (0.11, 0.44 µg/ml), respectively. Generally, CP-AgNPs have excellent potential application for the photocatalytic degradation of organic pollutant and in the development of antibacterial materials. [ABSTRACT FROM AUTHOR]
