A simple sol-gel condensation of tin(iv) tert-butoxide led to the formation of meso/macroporous membranes. SEM observation clearly shows the cylindrical macropore array, of which mean pore diameter is controllable between 200 and 800 nm. The existence of slit-shaped mesopores (12 nm) was confirmed by a N 2 adsorption-desorption experiment.
