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-depen
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...
The XRD pattern of PCN-224 reveals characteristic peaks at around 2θ = 4.62◦, 6.54◦, 7.90◦, 9.12◦, and 11.14◦, which represents the crystal planes of (0 0 2), (0 2 2), (2 2 2), (0 0 4), and (2 2 4), respectively. These previous characterization ...
