N2 - Monodisperse mesoporous silica microparticles (50 to 100 μm) can be produced via a microfluidic jet spray-drying route, using cetyl trimethylammonium bromide (CTAB) or pluronic F127 as templating agents, and tetraethylorthosilicate (TEOS) for silica. The microparticles demonstrate highly ordered hexagonal mesostructures with surface areas from ~ 900 up to 1500 m2/g and pore volumes from ~ 0.6 to 0.8 cm3/g. Here, the spray drying of dual surfactant-templated silica, and dual-surfactant templated carbonsilica composites are presented, with discussion on the possible interactions governing meso- and macro-structure formations and the hierarchical structures formed through evaporation-induced self assembly via spray drying.
