Abstract

Spherical palladium nanocrystals were generated from aqueous Na₂[PdCl₄] via photosynthetic reactions within green microalgae (Chlorella vulgaris). Electrospun chitosan mats were effective for immobilizing these biogenic nanocrystals, as a material for recycling as a catalyst for the Mizoroki–Heck cross-coupling reaction. This photosynthetically-driven metal transformation system can serve as a good candidate for an environmentally-friendly method for the synthesis of metal nanocatalysts.
