摘要: The mesoporous solid SBA-2, prepared at room temperature in alkaline pH using the gemini surfactant [CH3(CH2)15N(CH3)2(CH2)3N(CH3)3]2+ can adopt hollow sphere (ca. 100 μm diameter), flat plate (50 μm across) and small (1–2 μm diameter) morphologies. Plates appear to be formed directly by fracturing of spheres. nanostructure these materials is consistent with templating around close packed micelles. X-Ray diffraction high resolution imaging show that structure preparations ranges from mainly hexagonal cubic packing.
