Palladium-Based Nanostructures with Highly Porous Features and Perpendicular Pore Channels as Enhanced Organic Catalysts

(Reported by Jie He)

A convenient and effective wet-chemical strategy that produces uniform highly porous palladium nanostructures (pPdNs) with perpendicular pore channels was reported. The pPdNs with perpendicular pore channels was prepared in aqueous solution at ambient temperature using hexadecylpyridinium chloride (HDPC) as the shape-directing agent, without the need of premade seed structures, organic solvents, or hard templates. The obtained pPdNs exhibit better catalytic activity than commercial Pd black and a home-made Pd catalyst for the hydrogenation of nitrobenzene, styrene, and also a Suzuki coupling reaction, making them promising for advanced catalytic applications.
