Palladium Supported on Mesoporous Silica via a Two-Step Method as an Efficient Catalyst for Suzuki-Miyaura Coupling Reactions

Abstract:

In this paper, palladium-containing SBA-15 (Pd/SBA-15) was synthesized via a two-step method. In this procedure, Pd nanoparticles of 3-5 nm in size have been synthesized by formalin reduction method and incorporated into mesoporous SBA-15 silica during hydrothermal synthesis. The resulting nanocomposite with 1.20 wt% Pd loading was achieved with highly dispersed and uniform palladium nanoparticles. The catalytic activity of the Pd/SBA-15 nanocomposite was used as a catalyst for the Suzuki-Miyaura coupling reactions. The Pd/SBA-15 nanocomposite exhibited excellent catalytic activities and reuse ability in air for the Suzuki-Miyaura coupling reactions.
