Description
| - 27Al 3Q MAS NMR spectroscopy and DFT/MM calculations were employed to study the Al siting in eleven differently synthesized samples of the ZSM-5 zeolite. The results of our study reveal that the occupation of the distinguishable framework T sites by Al and the concentration of Al in these T sites are neither random nor controlled by a simple rule. They both depend on the conditions of the zeolite synthesis. We further found that at least 10 out of the 24 distinguishable framework T sites are occupied by Al in our ZSM-5 samples.

- 27Al 3Q MAS NMR spektroskopie a DFT/MM výpočty byly užity pro studium sitingu Al v jedenácti rozdílně syntetizovaných vzorcích zeolitu ZSM-5. Výsledky studie ukazují že obsazování rozlišitelných mřížkových T poloh hliníkem a koncentrace Al v těchto polohách nejsou náhodné nebo řízené jednoduchým pravidlem. Jak obsazování T poloh, tak koncentrace Al v nich závisí na podmínmkách syntézy zeolitů. Dále bylo zjištěno že nejméně 10 z 24 rozlišitelných mřížkových T poloh bylo obsazováno hliníkem ve zkoumaných vzorcích. (cs)
