Biosynthesis of waste pistachio shell supported silver nanoparticles for the catalytic reduction processes

Abstract

Silver nanoparticles (NPs) are immobilised on pistachio shell surface by L. leaves extract as an antioxidant media. The Fourier transform infrared spectra, X-ray diffraction, field-emission scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy, and transmission electron microscope analyses confirmed the support of silver NPs on the pistachio shell (Ag NPs/pistachio shell). Ag NPs on the pistachio shell had a diameter basically in the 10-15 nm range. Reduction reactions of 4-nitrophenol (4-NP), and organic dyes at ambient condition were used in the investigation of the catalytic performance of the prepared catalyst. Through this research, the Ag NPs/pistachio shell shows a high activity and recyclability, and reusability without loss of its catalytic activity.

Immobilization of biogenic metal nanoparticles on sustainable materials – green approach applied to wastewater treatment: a systematic review

“…Agriculture wastes can be used as supports for biogenic MNP as is the case of the shells of almonds, 132,133 walnuts, 22 peaches, 4 pistachios, 134,135 hazelnuts, 136 wheat bran and rice bran 93 and seeds of Russian olives. 137 The catalytic performance of green Pd-NP supported on modified almond shells was studied.…”

Synthesis of Silver Nanoparticles: From Conventional to ‘Modern’ Methods—A Review

“…In many instances, ligand-stabilized NPs are synthesized first, followed by the formation of shell structures by ligand exchange [86]. Different AgNPs with coating shells, such as metal-AgNPs, pistachio-AgNPs, silica-AgNPs, have been evaluated by scientists [109][110][111].…”
