“…However reduction of Cr(VI) in the presence of noble metal nanoparticles like Pd, an additional reducing agent is needed while noble metal nanoparticles act as catalyst to speed up the reduction of Cr(VI). Catalytic reduction of Cr(VI) using Pd nanoparticles stabilized by different supporting systems has been widely documented in literature ( Veerakumar and Lin, 2020 ). For example, Omole et al (2007) have reported palladium nanoparticles in N,N -dimethylformamide for catalytic reduction of Cr (VI) using formic acid as hydrogen source.…”

“…The chelation between the support and the PdNPs stabilizes the nanoparticles and prevents the agglomeration phenomena, consequently increasing the catalytic activity and facilitating its recovery and reuse. Various supports have been developed for anchoring and stabilizing PdNPs such as organic polymers, inorganic materials, organic-inorganic hybrids and carbon materials [4][5][6][100][101][102][103][104].…”

Among transition metal nanoparticles, palladium nanoparticles (PdNPs) are recognized for their high catalytic activity in a wide range of organic transformations that are of academic and industrial importance. The increased interest in environmental issues has led to the development of various green approaches for the preparation of efficient, low-cost and environmentally sustainable Pd-nanocatalysts. Environmentally friendly solvents, non-toxic reducing reagents, biodegradable capping and stabilizing agents and energy-efficient synthetic methods are the main aspects that have been taken into account for the production of Pd nanoparticles in a green approach. This review provides an overview of the fundamental approaches used for the green synthesis of PdNPs and their catalytic application in sustainable processes as cross-coupling reactions and reductions with particular attention afforded to the recovery and reuse of the palladium nanocatalyst, from 2015 to the present.

“…Recently, the use of Pd NPs as sensors and catalysts has been investigated due to their remarkable properties. [ 32–37 ] It is of great interest that Pd NPs are obtained by the green synthesis method for catalysis, sensors, and biological applications. 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.…”

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.
