Synthesis of Frankincense gum stabilized AgNPs by microwave irradiation and their catalytic, antioxidant, and antibacterial properties

Herein, report the microwave irradiation synthesis of AgNPs using frankincense gum (FR) and their antioxidant, catalytic and antibacterial activities. The developed synthetic route for the synthesis of AgNPs is simple, eco-friendly, and economically viable. UV–visible, FTIR, powder XRD, DLS, and TEM techniques have been used for the characterization of synthesized FR@AgNPs. FTIR data demonstrated that the CO and –OH functional groups of frankincense gum were playing an essential role in the reduction and stabilization process of the synthesized FR@AgNPs. TEM and powder XRD measurements were confirmed that FR stabilized FR@AgNPs were well dispersed, spherical, and high crystallinity with a size of 7 ± 2 nm. In the presence of NaBH4, the catalytic potential of FR@AgNPs was verified for the reduction of Methyl Orange (MO), Rhodamine-B (Rh–B), and Methyl Red (MR) dyes. AgNPs exhibited significant catalytic efficacy for the degradation of MO, Rh–B, and MR dyes. The AgNPs have shown good antibacterial activity against the Bacillus subtilis, Bacillus series, Escherichia coli, and Pseudomonas aeruginosa. The DPPH radical scavenging mechanism was used to test the antioxidant potential of FR@AgNPs at various concentrations.
