Thirdly, the investigation of heteroatom is always of great interest and significance in zeolite science.

In addition, the amount of heteroatom substitution is another factor that can influence the hydrothermal stability.

本文还开发了另一种新颖的在强酸性体系中合成杂原子分子筛的方法—"pH-adjusting"方法。

At present, the direct synthesis of heteroatom doping SBA-15 study less [9-10]. Yue, etc.

At the same time several fused bicyclic heteroatom analogs were synthesized. Some of our Smac mimetics promote apoptosis in cancer cells.

与此同时，我们还合成了一些杂原子取代的并环Smac模拟物并测试其生物活性。

This is because heteroatom species have been fixed in the framework of the zeolite primary units when the seed solution is prepared and with the self-assembly of the zeolite primary units surrounding the surfactant, heteroatom species are directly introduced into the mesostructure.

这是因为在制备沸石导向剂的过程中，杂原子被固定在沸石的微结构单元中，当沸石导向剂与表面活性剂通过自组装过程形成介孔分子筛时，杂原子随沸石的微结构单元一起进入了产物的骨架当中。

When the mesostructure is basically formed, the pH value of the reaction system is adjusted to 7-8 and then the hydrothermal crystallization is prolonged for some time to obtain heteroatom-incorporated mesoporous silica. The aim of adjusting pH value to near neutral is to change heteroatom species from the cationic to oxo form and therefore can enter the mesoframework through condensation with silanol groups in the wall.

该方法主要的特点是：操作简单（以调节体系pH值代替繁琐的后处理过程），效率高（可以得到Si/Al=5且铝物种全部处于四配位的骨架位置的Al-SBA-15），不破坏产物有序结构（产品具有高度有序的介孔结构），具有普遍性（适用于多种杂原子的掺杂如铝、钛、钒）。
