Catalytic behavior of size-controlled palladium nanoparticles in the hydrodechlorination of 4-chlorophenol in aqueous phase

Size-controlled palladium nanoparticles show high activity in hydrodechlorination of 4-chlorophenol, with smaller nanoparticles showing higher activity due to higher available surface area.
