Procedure

SBA-15 is a mesoporous silica material. In this embodiment, PholTMS was co-condensed with a silica source to form phenol-functionalized platelet SBA-15, which is denoted by Phol-SBA-15-p. Then, phenol-functionalized platelet SBA-15 was sulfonated by concentrated H2SO4 to form phenolsulfonic acid-functionalized platelet SBA-15, which is denoted by PholSO3H-SBA-15-p.
