“…The rate constant calculated for PNA‐20Ag catalyzed reduction of 4‐NP with sodium borohydride is 0.2987 min −1 . Considerable enhancement in catalytic activity is observed, which is comparable or better than the catalytic activity reported recently by different groups with metal or metal oxide heterogeneous catalysts …”

A novel poly(1‐naphthylamine)‐silver (PNA‐Ag) nanocomposite has been prepared and used as a heterogeneous catalyst for the reduction of 4‐nitrophenol (4‐NP) and methylene blue (MB). In this study, silver nanoparticles (AgNPs) have been incorporated to PNA via a simple and fast one‐step route, where PNA acts as the reductant for silver ions and stabilizer for AgNPs. The prepared PNA‐Ag nanocomposites were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray diffraction (XRD), thermogravimetric analysis (TGA), energy dispersive X‐ray scattering (EDAX), and Fourier transform infrared (FTIR) spectroscopy. They provided ample evidence for the anchoring of AgNPs to the PNA chains. Enhanced electrochemical performance of the PNA‐Ag nanocomposite has been evidenced by cyclic voltammetry studies. Catalytic studies confirmed that the rate of reduction of both 4‐NP and MB with sodium borohydride have been enhanced significantly in the presence of AgNPs loaded PNA in comparison to neat PNA. This nanocomposite could find application as catalyst for reductive degradation of toxic organic pollutants. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48318.

“…The leaf extracts from various plants including Solanum trilobatum (Kanchana et al, 2010), Anacardium occidentale (Sheny et al, 2012), Catharanthus roseus (Kalaiselvi et al, 2015) were also utilized for the production of palladium nanoparticles. The catalytic activity of various metallic nanoparticles such as silver (Bindhu and Umadevi, 2015;Kundu, 2013;Narayanan et al, 2013), gold (Maity et al, 2012;Narayanan and Sakthivel, 2011;Praharaj et al, 2004;Sen et al, 2013), palladium (Dauthal and Mukhopadhyay, 2013;Kalaiselvi et al, 2015;Santoshi kumari et al, 2015), platinum (Coccia et al, 2012) and iridium (Kundu and Liang, 2011) was widely studied in reduction of various dyes.…”

A facile and green route for the synthesis of palladium nanoparticles from palladium chloride was developed using non-toxic, renewable plant polymer, gum ghatti (Anogeissus latifolia), as both the reducing and stabilizing agent. The generated nanoparticles were characterized with UV-visible spectroscopy (UV-vis), dynamic light scattering (DLS), transmission electron microscopy (TEM), and X-ray diffraction (XRD) techniques. The formation of palladium nanoparticles was confirmed from the appearance of intense brown colour and broad continuous absorption spectra in the UV-visible region. The produced nanoparticles were found to be spherical in shape, polydisperse and the average particle size was 4.8 ± 1.6 nm. The face centred cubic crystal structure of the fabricated nanoparticles is confirmed from the selected-area electron diffraction and XRD patterns. Compared to earlier reports, the nanoparticles showed superior antioxidant at a much lower nanoparticle dose. Also, the homogenous catalytic activity of palladium nanoparticles was studied by probing the reduction of dyes such as coomassie brilliant blue G-250, methylene blue, methyl orange, and a nitro compound, 4-nitrophenol with sodium borohydride. The nanoparticles exhibited excellent catalytic activity in dye degradation and the results of this study demonstrate the possible application of biogenic palladium nanoparticles as nanocatalyst in environmental remediation. ª 2015 The Authors.

Nanoparticles of silver, gold, palladium and platinum are widely applied in medicine, sensor, energy and catalysis and have been widely investigated for their unique physicochemical properties. Next to silver and gold nanoparticles, palladium receives extensive attention due to their distinctive size‐dependent catalytic performance. Traditionally, Pd nanoparticles have been synthesized using various physical and chemical methods involving sophisticated equipment and excessive chemicals. Expanding demand and the emerging economic/environmental concerns in synthesizing palladium nanoparticles created the necessity for the development of simple, eco‐friendly, and cost effective processes. Within this context, biological processes that use plants, microorganisms, enzymes and biochemicals have been used for the synthesis of Pd nanoparticles as the green alternative. The aim of this article is to review the recent biological trends in the synthesis of Pd nanoparticles employing various plants and their effective utilization.
