In this study, silica nanoparticle containing amine functional groups were prepared by syringe pumping method. After silica seed particles were synthesized by stöber method, the size of silica particles were controlled by injecting of additional silica precursor source using syringe pump. Finally, the silica nanoparticles were treated by different way of amine functionalization. Various sizes of silica nanoparticles having different amount of amines functional groups on surfaces were characterized in terms of their morphologies, electronic potentials, and catalytic activities. The catalytic activities of aminated silica nanoparticles were investigated through base-catalyzed model reaction with respect to degree of amination of silica nanoparticles.
