Abstract Palladium (Pd) nanoparticles have received significant attention in various metal-catalyzed transformations and cross-coupling reactions as recyclable and highly active catalysts. By the way, the applications of Pd nanoparticles remain limited by weakness in terms of their easy aggregation and the difficulty of catalyst product separation. Recently, deposition of noble metals (i.e. Au, Pt, Ag, and Pd) on n-type TiO2 nanoparticles has attracted considerable attention due to the uniqueness of their combinatorial interfacial properties and functions which are otherwise not available to either of the single components. In fact, Pd deposition on anatase TiO2 nanoparticles has been shown to enhance their catalytic activity in removal of organic pollutant. In this study, we synthesized Pd and TiO2-decorated CNT. And then study has been undertaken to investigate the UV irradiation effect on catalytic activities. A Pd-TiO2-CNT composite was prepared by a previously reported sol-gel method, whereby anatase TiO2 and metallic Pd nanoparticles were deposited onto the surface of CNTs. The prepared Pd-TiO2-CNT material was employed as a catalyst for the Heck reaction, and it showed higher catalytic activity in the presence of UV irradiation than in the absence of UV irradiation.
