[0051] 为研究PCN 222的结晶情况,对实施例1制备获得的PCN 222进行了XRD表征,其结 果如图3B所示。可以看出XRD谱图峰型较好,峰值为5.86°,7.86°,8.30°和10.63°,证明了结 晶晶体主轴为六面体,这与SEM表征结果高度一致。同时该表征也进一步证明了成功合成了 PCN 222晶型材料。
其实验结果如图3A所示,该PCN 222材料具有非常好的热稳定性,升温至450°C基本无明显失重(>85%),即使升温至600°C,仍保持有65%左右的重量。 为研究PCN 222的结晶情况,对实施例1制备获得的PCN 222进行了XRD表征,其结果如图3B所示。可以看出XRD谱图峰型较好,峰值为5.86°,7.86°,8.30°和10.63°,证明了结晶...
Thermogravimetric analysis provided relevant information on the composition and thermal stability of both materials in complement with other techniques (energy-dispersive X-ray spectroscopy X-EDS, thermal-dependent XRD). In general, decomposition of (Hf)PCN-224(H2) occurred faster than for (Hf)PCN-22...
能具体说说你用的什么方法吗？我也用水热釜和油浴合成了，结果xrd图谱与单晶对比，有一些偏差。我用的...
The crystal structures of the PPTP-3 and its various components were analyzed by XRD (Figure 2b). The crystal structures and the position of diffraction peaks hardly change after TiO2 modification, indicating that KH-570 grafting on the TiO2 surface can not affect its crystallinity. Furthermore,...
