Palladium supported on mesoporous silica via an in-situ method as an efficient catalyst for Suzuki–Miyaura coupling reactions

•Palladium-containing SBA-15 (Pd/SBA-15) was synthesized via an in situ approach.•The resulting sample with 1.46 wt% Pd loading was achieved with highly dispersed and uniform palladium nanoparticles.•The Pd/SBA-15 exhibited excellent catalytic activities and reuse ability in air for the Suzuki–Miyaura coupling reactions.

Palladium-containing SBA-15 (Pd/SBA-15) was synthesized via an in situ approach. In this procedure, the hydrophobic solvent (CHCl3) was used as a transport medium to inject the Pd precursor (Pd(acetylacetonate)2) directly into the inner core of the surfactant micelles. The resulting nanocomposite with 1.46 wt% Pd loading was achieved with highly dispersed and uniform palladium nanoparticles. The Pd/SBA-15 nanocomposite exhibited excellent catalytic activities and reuse ability in air for the Suzuki–Miyaura coupling reactions.

In this procedure, the hydrophobic solvent (CHCl3) was used as a transport medium to inject the Pd precursor (Pd(acac)2) directly into the inner core of the surfactant micelles. The resulting nanocomposite with 1.46 wt% Pd loading was achieved with highly dispersed and uniform palladium nanoparticles.
