“…The binding energy peaks at 335.4 eV and 340.5 eV corresponded to the spin-orbit splitting components, Pd 3d5/2 and Pd 3d3/2, respectively. The observed binding energy values for Pd 3d coincided with the reported values of Pd(0) [ 61 ], which confirms the successful biosynthesis of PdNPs in the zero-oxidation state using M. recutita flower extract.…”

The green chemistry method is the preferred approach for synthesizing metal and metal oxide nanoparticles because of its low toxicity, environmental friendliness, feasibility, and safety to human health compared with other chemical or physical methods. The present work reports the phytogenic synthesis of palladium nanoparticles (PdNPs) using an aqueous extract of Matricaria recutita (Chamomile). The phytochemical-mediated synthesis of PdNPs is an economical and eco-friendly approach without using toxic elements as reducing and capping or stabilizing agents. The UV-visible spectroscopic characterization was initially used to confirm the preparation of PdNPs using an aqueous extract of M. recutita flowers as a bioreductant for the reduction of Pd2+ to Pd0 without using any extra capping and reducing agents. The appearance of surface plasmon resonance (SPR) peak at 286 nm confirmed the formation of M. recutita extract-based PdNPs. Furthermore, the PdNPs were characterized by TEM, SEM, EDX, XRD, XPS, and FTIR to confirm their proper synthesis. The thermogravimetric analysis (TGA) was implemented to interpret the decomposition pattern and thermal stability of as-synthesized PdNPs. The biosynthesized PdNPs were further applied as a nanocatalyst in degradation of an azo dye Congo red (CR) in the presence of NaBH4. The catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) was also investigated in the presence of NaBH4. All the catalytic reactions were performed in water, and no significant loss in catalytic activity was observed after recovery and reusability of the biosynthesized PdNPs.

“…It has been found that Pd NPs synthesized by the green synthesis method have outstanding antioxidant properties, but their activity is not yet fully determined. [ 38 ] Han et al [ 39 ] reported that they synthesized LNT stabilized palladium nanoparticles (Pdn‐LNT NPs) by green synthesis method. They observed that Pdn‐LNT NPs had high cytotoxic and antioxidant activity.…”

Green synthesis is considered to be one of the most suitable method because it enhances the therapeutic effects of palladium nanoparticles (Pd NPs). In this study, various biological activities such as antimicrobial, anticancer, antioxidant, and DNA cleavage activities of Urtica-mediated green synthesizing Pd NPs were investigated. The synthesized Pd NPs were characterized by using UV-vis, XPS, FT-IR, TEM, and XRD analyses. As a result of the TEM analysis of Pd NPs, the mean particle size was found to be 7.44 ± 1.94 nm, and this result was supported by XRD analysis. The maximum DPPH scavenging activity was determined as 79.6% at 500 mg/L. The newly green synthesized Pd NPs exhibited high antimicrobial activity to gram-negative bacteria than grampositive bacteria. Urtica-mediated green synthesized Pd NPs also showed double strain DNA cleavage activity. For the cytotoxic effects of Pd NPs, the MDA-MB-231 breast cancer cell line, HT-29 colon cancer cell line, Mia Paca-2 human pancreatic cancer cell line, and healthy cell line L929-Murine fibroblast cell line were used. IC 50 values of Pd NPs against MDA-MB-231, HT-29, and MIA PaCa-2 cancer cell lines were calculated as 31.175, 20.383, and 29.335 μg/ml, respectively. No significant cytotoxic effect was observed in the healthy lines L929.

The reasonable control of the dispersion of noble metals is an important topic for heterogeneous catalysts. In this manuscript, PdCu/C, AuCu/C and PdAuCu/C were prepared by the galvanic reduction method to ensure that Pd and Au follow the distribution of Cu nanoparticles. The catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), energy-dispersive spectrometer elemental mappings and lines scans. Both the Pd and Au had very high dispersion no matter whether they were introduced individually or simultaneously. The Pd and Au were distributed mainly on the Cu nanoparticles as evidenced by the energydispersive spectrometer elemental mappings and lines scans. The reduction of 4-nitrophenol was used as a model reaction for the prepared catalysts. PdCu/C and AuCu/C showed high activity for this reaction compared to the literature, and the activity could be further increased by the introduction of Pd and Au in an appropriate ratio at the same time. The normalized reaction rate reached 2.005 s À 1 mM À 1 for the PdAuCu/C-2.0, in which the mole ratio of Pd to Au was 2.0.
