摘要：

A solution phase UV-photoactivation technique has been reported to prepare palladium nanoparticles. Aqueous H2PdCl4 solution was irradiated under UV-light (similar to 365 nm, 340 lux) in a nonionic surfactant solution to produce Pd(0) nanoparticles. The particles generated in this method are stable, spherical and small (5-10 nm) with a tight size distribution. Catalytic activity of the photoproduced palladium nanoparticles has been substantiated through photodecolorization of aqueous acridine orange solution. It has been found that the photoproduced palladium nanoparticles have a profound influence on the reaction rate and the rate varies linearly with nanoparticle concentration.
