Understanding the condensation process of two precursors in the Stöber process is crucial to enhance the complexity and applicability of silica hybrids. We present a simple and effective method to prepare functional silica hybrid particles with tunable properties through the co-condensation of tetraethoxysilane and an organoalkoxide precursor using a modified Stöber process. Three organoalkoxide precursors have been studied: (3-mercaptopropyl)triethoxysilane, (3-cyanopropyl)triethoxysilane, and (3-aminopropyl)triethoxysilane. All three investigated systems produce functional silica hybrid particles, as confirmed by various characterization techniques. Scanning transmission electron microscopy and nitrogen sorption analysis demonstrated that features such as the microstructure could be tailored by the careful selection of the second precursor. A drastic increase in the specific surface area can be obtained with 3cyanopropyltriethoxysilane: 270 m
