Abstract

This study reported the synthesis of well-dispersed palladium nanoparticles (PdNPs) using microwaves. Additionally, this method is quick, cheap, chemical-free, and environmentally friendly. The Eupatorium adenophorum aqueous extract, which contains polysaccharides and other phytochemicals, effectively reduced and stabilized PdNPs. We have preliminarily confirmed that PdNPs form via UV�visible spectroscopy and proposed a mechanism of PdNPs formation via Fourier transform infrared spectroscopy. EA-PdNPs have a face-centred cubic structure, as confirmed by XRD analysis. The images obtained by transmission electron microscopy showed spherical PdNPs whose average size was 11 ± 2 nm. EA-PdNPs showed good catalytic activity towards the reduction of methylene blue (MB), congo red (CR) dyes, and 4-nitrophenol (4-NP). It was found that EA-PdNPs showed a reduction efficiency of 94 against MB, CR, and 4-NP dyes even after five cycles. EA-PdNPs are anticipated to contribute to environmental water remediation significantly.
