Abstract

Monodisperse silica core–shell particles with a high surface area and large pore size were rapidly prepared via a multilayer-by-multilayer (ML-b-ML) process, with 6–7 layers of silica nanoparticles deposited per coating cycle onto an oppositely charged polyelectrolyte in 0.1 M NH4NO3 at pH 2.7. The resultant porous shells show much greater porosity compared to particles obtained by the traditional layer-by-layer process.
