摘要

Abstract A family of ordered mesoporous silica chloride (SBA-Cl) with 2D P 6 mm hexagonal structures and high surface areas was prepared through treatment of SBA-15 with thionyl chloride. The materials were shown to have excellent catalytic activity in Beckmann rearrangements of ketoximes. The catalyst (SBA-Cl-2) was recovered and reused for at least three reaction cycles without significant change in its nanostructure as evidenced by ...
