在酸性合成法基础上,不添加有机共溶剂和其它模板剂,通过加入少量NH4F和Cu(NO3)2得到了分散的球状形貌SBA-15粒子.对所得样品用小角X射线衍射(XRD)、N2吸脱附曲线、扫描电镜(SEM)进行表征,讨论了不同电解质对样品形貌和孔结构的影响.结果发现,随着酸浓度增加,得到了分散的规则六边形SBA-15粒子,而加入一定量的氟化铵则得到了球形纠结状形貌的SBA-15.实验表明,氟离子在形成球状粒子的过程中起主要作用,而Cu2+阻碍了球状粒子的纠结.随着Cu2+浓度的增加,部分硅源不能参与自组装生成SBA-15,其原因可能是Cu2+与模板剂中亲水的聚氧乙烯形成PEO/Cu2+端基,影响了硅源正常的缩聚.
