This article describes pioneer work in the field of mesoporous materials. Today, over 11 Years ago, the so called SBA Materials are some sort of standard materials - at least in the academic field. The synthesis of the Materials using template P123 are very good reproducible. Unfortunately -to my knowledge- only pores with diameters up to ~100 Angstroms can be synthesised using the P123. In my experiments I failed synthesising Materials with bigger pores using L121. I could only obtain amorphous, non porous stuff with these template. Is there anyone outside who was able to succeed? I need urgently some 300 Angstrom SBA for my further research. Kind Regards Angie
