Palladium nanoparticles (PdNPs) have been synthesized through various approaches utilizing different nanotechnological methods. Among these, green synthesis has been adopted to minimize environmental impact and avoid the use of hazardous chemicals. Many scientists advocate for green synthesis due to its simplicity, cost-effectiveness, and eco-friendly nature.

The unique properties of palladium nanoparticles are currently a subject of extensive research. Using plant extracts for their synthesis has shown promising results, offering diverse functional attributes and applications. This paper explores the optical, plasmonic, magnetic, and catalytic properties of PdNPs.

Palladium nanoparticles have gained significant attention for their applications in catalysis, antioxidant and antimicrobial activity, and as sensors for hydrogen and glucose. Their catalytic efficiency is notably influenced by the particle size, which enhances their performance in various chemical processes.
