Abstract: A new facile and reliable route for synthesis of nano-sized Pd(0) particles onto zeolitic matrix has been developed. [Pd(NH₃)₄] ₂₊ ions have been first immobilised in NaY matrix by ion exchange, then upon reaction with hydrazine hydrate [Pd(NH₃)₄] ₂₊ ions were directly reduced to nano-sized Pd(0) particles almost instantaneously. Transmission electron microscopic (TEM) analysis reveals that well separated nano-sized (10-20 nm) palladium(0) particles have been formed onto the surface of the zeolite crystals. X-ray powder diffraction analysis supports that the particles are highly dispersed in the zeolite matrix. The prepared nano-composite is found to be highly catalytically active in a variety of Heck cross-coupling reactions.
