摘要 研究采用有机金属化学气相沉积(MOCVD)法,以乙酰丙酮铜Cu(acac)2为前驱物对SBA-15孔结构进行修饰,制备出结构均匀的ink-bottle孔体系.该制备过程中,基质SBA-15的表面特性对于合成结构良好的ink-bottle孔有重要影响,SBA-15经进行适度的镀碳处理后,其表面由亲水表面变为憎水表面,有利于后续有机金属选择性的吸附和沉积,从而实现对SBA-15孔口的修饰,即保持了SBA-15原有的较大比表面积和孔体积的同时使其孔口尺寸明显减小,得到ink-bottle孔结构.MOCVD法首次成功应用于ink-bottle孔制备过程中,对于合成不同孔结构介孔材料领域的研究具有重要意义.
