“…For instance, a RGO/Fe3O4 based nanocomposite with Pd NPs has been synthesized via a green route by Withania coagulans leaf extract as a reducing and stabilizing agent and its catalytic activity has been tested for the reduction of 4-NP in water with good results. The hydroxyl groups of phenolics in W. coagulans leaf extract is directly responsible for the reduction of Pd 2+ , Fe 3+ ions and GO [89]. A green synthesis of the Cu/Fe3O4 NPs using Silybum marianum L. seeds extract and their application as magnetically separable nanocatalyst for the reduction of nitroarenes have been reported [90].…”

“…The Pd NPs/RGO exhibited catalytic activity for the reduction of nitroaromatic compounds with excellent reusability up to 5 cycles without reduction of the catalytic activity. In addition to that, a research article from the same research group demonstrates the synthesis of Pd nanoparticles supported on reduced graphene oxide/Fe 3 O 4 by a Withania coagulans leaf extract‐mediated green process . The synthesized composite material has successfully been explored for the aqueous reduction of 4‐nitrophenol (4‐NP) at ambient temperature .…”

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.

“…Recently, nano noble metals functionalized rGO have been extensively attentions because of combining the merits of both rGO and nano noble metals. Palladium (Pd), one of important catalyst of noble metals, was employed to form diverse Pd functionalized rGO, which was selected for the architecture of high-efficient electrochemical sensors and their application in electrochemical analysis [34][35][36][37][38].…”

Vitamin K 3 (VK 3 ), a synthetic blood coagulation vitamin with fat-solubility, easily results in side-effect in animal body due to its toxicity and improper addition of animal feedstuffs. In this study, a novel sensor based on glassy carbon electrode (GCE) modified with a conducting polymer-both nano-noble metals and two-dimensional nano-carbon composite consisting of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), carboxymethyl cellulose (CMC) and reduced graphene oxide@palladium (rGO@Pd) was successfully used for the voltammetric detection of VK 3 in animal blood and feedstuff samples. Under the optimized conditions, PEDOT:PSS-CMC-rGO@Pd/GCE/GCE displayed the excellent synergistically electrocatalytic ability for the electrochemical oxidation-reduction of VK 3 , which exhibited a good voltammetric response for VK 3 in the concentration range from 4 × 10 -7 to 9 × 10 -5 M, with a limit of detection of 1.4 × 10 -8 M. Furthermore, a facile preparation, high sensitivity, good selectivity, superior sensing stability, and satisfactory practicability of PEDOT:PSS-CMC-rGO@Pd/GCE/GCE for sensing VK 3 suggested that the potential applicability of PEDOT:PSS-CMC-rGO@Pd provided a promising electrochemical sensing platform for the determination of VK 3 in pharmaceutical and feed inspection.
