Synthesis of MCM-41 via different routes

This review focuses the different routes for MCM-41 synthesis such as nano-sized mesoporous silicas with metal oxide incorporation, from Glycerol and Ethylenediamine, from different dioxosilicon sources, synthesis of pure siliceous MCM-41 with different pore diameter, synthesis highly ordered MCM-41 with mixed surfactants, and synthesis from rice husk ash. The emerging characteristic of synthesized MCM-41 by these different routes was also discussed such as surface morphology, surface area, pore diameter and crystal sizes of MCM-41 in this review.
