Original titania nanocages are fabricated from sacrificial silica/polystyrene tetrapod‐like templates. Here the template synthesis, titania deposition and nanocage development through polystyrene dissolution and subsequent silica etching are described. Discussion about the competitive deposition of titania on the biphasic templates is particularly emphasized. The morphology of the nanocages is investigated by TEM, STEM, EDX mapping and electron tomography.

模板导向的四面体排列的打开窗口的Titania纳米笼的合成

原始的二氧化钛纳米笼由牺牲性二氧化硅/聚苯乙烯四脚架样模板制成。在这里描述了模板合成，二氧化钛沉积和通过聚苯乙烯溶解以及随后的二氧化硅蚀刻形成的纳米笼。特别强调了关于二氧化钛在双相模板上竞争性沉积的讨论。通过TEM，STEM，EDX作图和电子断层扫描研究了纳米笼的形态。
