Patent ID: 7815883

Claim:
A method of forming an organic-functionalized and zirconium doped mesoporous silica with platelet morphology and short mesochannels having a channel length of about 100-350 nm, comprising: adding EO 20 PO 70 EO 20 , silicon source, organosilane and Zr(IV) ions into a HCl solution to form a synthesis solution, wherein the molar ratio of EO 20 PO 70 EO 20 , silicon source, organosilane, Zr(IV) ions, HCl and H 2 O is 0.008-0.02:1:0.05-0.3:0.03-0.1:4-12:100-310; hydrothermally heating the synthesis solution to form the mesoporous silica; and removing EO 20 PO 70 EO 20 from the pores of the mesoporous silica.
