Popis: The control of both poly condensation of the titanium alkoxide, [Ti(OR) 4 ], and alkoxide coverage of the templating monodispersed polystyrene (PS) beads in suspension lead to various morphologies of macroporous solids after calcination. By increasing the ratio H 2 O/[Ti(OR) 4 ], the solids progressively evolve from a dense interconnected macroporous network to almost isolated hollow spheres characterized using SEM.
