Ag nanoparticles were impregnated in sub-micrometer crystalline jute cellulose particles by green method and evaluated the performance in catalytic degradation of dye and in antibacterial agent. [Display omitted] •Submicrometer crystalline jute cellulose (SCJC) particles were prepared.•Impregnation of Ag nanoparticles in SCJC particles.•Interaction of SCJC particles with Ag nanoparticles.•Exhibited catalytic and antibacterial properties. This work discussed the preparation of Ag nanoparticles (AgNPs) and AgNPs impregnated sub-micrometer crystalline jute cellulose (SCJC) particles using a green synthetic bioreduction method. The ultimate nanocomposite particles were named as SCJC/Ag. The crystalline structure of AgNPs was maintained in SCJC/Ag nanocomposte particles. The catalytic efficiency of SCJC/Ag nanocomposite particles were evaluated for the degradation of congo red (CR) and methylene blue (MB) using NaBH4 as reducing agent. A complete degradation of 20 mL of each CR (0.1 mM) and MB (0.05 mM) dye solution was achieved within 14 min when 0.005 mg mL−1 of SCJC/Ag nanocomposite particles was employed. SCJC/Ag nanocomposite particles also exhibited moderate antibacterial activities against Staphylococcus aureus, Escherichia coli, Shigella dysenteriae and Shigella boydii and the results were comparable with those of the reference AgNPs. SCJC/Ag nanocomposite particles were the most effective against Escherichia coli (E. coli) with minimum inhibitory concentration of 0.014 mg mL-1.
