Amidine polystyrene (PS) beads and amphiphilic triblock copolymers are simultaneously assembled inside an emulsion with tetraethyl-orthosilicate (TEOS) as silica source, which form composite structured particles during the evaporation of droplets. By burning out PS beads and the triblock copolymers, spherical meso-macroporous silica particles were produced in powder form. The size of macropores could be controlled with a size of PS beads. Resulting hierarchically porous particles have more than three times the specific surface area of simple macroporous particles. Consequently, these meso-macroporous particles have high potential use in various applications requiring large surface-to-volume ratio, including catalytic supports, adsorbents, or drug carriers.", }
