Fucoidan-mediated green synthesis of palladium nanoparticles as a recyclable catalyst for Heck coupling and alkyne reduction in pheromone synthesis.

ABSTRACT: The development of sustainable routes for metallic nanocatalysts remains challenging due to the reliance on toxic reagents and harsh synthesis conditions. To address this, a green and efficient method was established for the preparation of palladium nanoparticles (PdNPs@Fu) using fucoidan, a naturally occurring polysaccharide with several hydroxyl and sulfate groups as a stabilizing and reducing agent. Fucoidan can rapidly reduce Pd²⁺ to Pd⁰ in aqueous medium under microwave irradiation (450 W, 10 min). The resulting PdNPs@Fu exhibited uniform crystalline nanoparticles (sizes ranging from 2-6 nm and an average diameter of 3.83 ± 0.09 nm), with long-term colloidal stability over 30 days. Catalytic studies demonstrated remarkable activity in model organic transformation
