Antibacterial and catalytic properties of silver nanoparticles loaded zeolite: green method for synthesis of silver nanoparticles using lemon juice as reducing agent

Abstract

Zeolite Y is a cage-like alumina silicate which is widely used as solid support to immobilize metal and metal sulfide nanoclusters. We have attempted to synthesis silver nanoparticle-loaded zeolite Y by an ion exchange method followed by a biogenic reduction method using lemon juice as a reducing agent. The antimicrobial activity of the silver ion, silver nanoparticles and silver chloride-modified zeolite was investigated against various Gram negative and Gram positive microorganisms. The silver nanoparticle-loaded zeolite was further functionalized with amoxicillin antibiotic which exhibited a strong antimicrobial action to kill drug resistant microorganisms. The catalytic behavior of silver nanoparticles was investigated to reduce 4-Nitrophenol in presence of NaBH 4 . The catalytic reaction is found to be pseudo-first order, resulting in a rate constant that was comparable with previously-reported results.

Phytochemical Process for the Functionalization of Materials with Metal Nanoparticles: Current Trends and Future Perspectives

“…They found that the Cu/ Natrolite zeolite functional nanoparticles took only 30 min for N‐formylation of benzylamine with the yield of 94% which is higher than any other catalysts . Selvamuthumari et al., immobilized the Ag nanoparticles within zeolite‐Y by employing ion exchange method followed by the biogenic reduction process using lemon juice as a reducing agent for Ag 2+ ions. The obtained Ag nanoparticle functionalized zeolite‐Y showed excellent catalytic performance in reducing 4‐NP and antimicrobial activity against Bacillus subtilis and Salmonella typhi bacterias .…”

Hatamifard and his co‐workers synthesised the functional Ag/zeolite nanostructures using Euphorbia prolifera leaf extract as the reducing agent for silver ions.…”

Biogenic synthesis of a silver nanoparticle–SnZrMoP nanocomposite and its application for the disinfection and detoxification of water

“…To overcome these demerits, biogenic nanoparticles synthesized from plant extracts without making use of any poisonous chemicals would be considered attractive for nanotechnology. 10 The phytochemicals present in plants are water soluble and can cause the immediate reduction of metal ions. 11 A number of medicinal plants, such as Acorus calamus, Alternanthera dentate, Ocimum sanctum, Azadirachta indica, Brassica rapa, Coccinia indica, Vitex negundo, Solanum xanthcarpum, Croton bonplandianum, Andrographis paniculata, and Cleome viscosa, have been reported in literature for the synthesis of biogenic Ag nanoparticles.…”
