Isomorphic Ti substitution into SBA-15 without Ti loss and with lower TiO2 segregation.


A convenient method has been discovered to incorporate Ti atoms isomorphically into a SBA-15 lattice without Ti loss. By hydrolysis of a Ti precursor near neutral pH instead of conventional acidic conditions, Ti loss was almost eliminated and its segregation to form TiO2 particles was suppressed while the mesoporous structure remained intact.
