The aim of this study is to design and synthesize a new type of mesoporous silica supported palladium catalyst and apply it to the carbon-carbon coupling reaction to explore its catalytic activity and selectivity. In this study, mesoporous silica (MCM-41) support was synthesized by Sol-Gel method, and supported palladium catalyst was prepared by using ammonia to adjust pH and nitric acid palladium precursor. The catalyst was characterized by XRD, TEM, N2 adsorption-desorption and other characterization methods, and the results showed that the synthesized catalyst had high specific surface area, adjustable pore size and good crystallinity. The catalytic activity and selectivity of the catalyst were investigated by carbon-carbon coupling reaction (Suzuki reaction), and the results showed that the catalyst had good catalytic effect and high selectivity, providing a new idea for the development of efficient catalysts.Keywords: mesoporous materials, supported catalyst, carbon-carbon coupling, palladium
