如图10所示,合成的Ce(III)-MOF的PXRD谱图与模拟的谱图的主要衍射峰比对一致,并且与已报道的文献中的衍射峰位置比对一致,证明已成功制备了Ce(III)-MOF。经过部分氧化后生成的Ce(III,IV)-MOF的PXRD与Ce(III)-MOF的主要衍射峰比对一致,说明经过部分氧化后只是改变了金属Ce的化合价,并没有改变它原来的结构。 (六...
XRD spectra was performed using D8 ADVANCE (Germany) with CuKĮ (1.5406 Å) radiation. Nitrogen adsorption–desorption isotherms were examined using a Quantachrome Quadrasorb EVO apparatus (Quantachrome Instruments, Boynton Beach, USA). XPS (Thermo ESCALAB 250XI) was used to measure the ...
Finally, the structure of was determined by FT-IR, ICP, XRD, BET, EDX, SEM, SEM-mapping, TEM, and TGA-DTA techniques and used as a new and potent nanocatalyst for the synthesis of tetrazoloquinazolines . One of the advantages of this nanocatalyst is the active surface to form products...
[11] was confirmed by our VTXRD and TGA measurements. Differently from D'Arras et al. [11] we found a discrete surface area due to microporosity through N2 adsorption isotherms at −196 ◦C (about 220 m2/g) after thermal activation in the 250–450 ◦C range. XAS confirmed the ...
