In this study, we developed a novel catalysts consisting of periodic mesoporous organosilica functionalized with bipyridinium ionic liquid supported palladium. The physiochemical properties of the hybrid catalyst were investigated using Fourier transform infrared spectroscopy, small angle X–ray powder diffraction, field emission scanning electron microscope, transmission electron microscope, nitrogen adsorption–desorption analyses, and atomic absorption spectroscopy. The stabilized Pd species inside the mesochannels provided good catalytic efficiency for the Suzuki–Miyaura coupling reactions in water. The activity of the designed catalysts retained for several consecutive recycle runs. The stability, recoverability, and reusability of the designed heterogeneous catalyst were also studied under various reaction conditions.

bridge dimeric organic functional group viologen PMOs synthesized via layer by layer growth on titania (TiO 2 ) has been unprecedently prepared as stable periodic mesoporous organosilica using surfactant under mild acidic conditions. The layer by layer TiO 2 incorporation within the prepared organic functional group viologen-PMO could successfully develop a new type of hybrid photo-oxidation system for the mineralization of formic acid under sunlight irradiation conditions.[a] M.
