A new synthesis strategy for ordered mesoporous carbon with precisely controllable pore sizes in the range of 3 to 10 nm using an inorganic pore expanding agent is demonstrated. The synthesis mechanism involves the formation of borosilicate and boron oxide nanolayers between carbon framework and silica surface within the mesopores of the silica template caused by spontaneous phase separation and subsequent solid state reaction during carbonization.
