Abstract
Superficially porous silica particles are provided as well as a one-pot process for making the superficially porous particles, the process comprising hydrolyzing and condensing a silica precursor comprising a functional group to form superficially porous particles, the superficially porous particles comprising silica microparticles having silica nanoparticles bound to the surface of the microparticles. The nanoparticles provide a porous outer layer on the microparticles. The superficially porous particles are useful as a stationary phase in liquid chromatography and allow for fast mass transfer and separation of samples.
