原位固体核磁共振研究温和条件下丙烷在镓改性H-ZSM-5上的活化
In situ MAS NMR Study on Propane Activation over Ga-modified H-ZSM-5 Under Mild Condition
【Abstract】 C MAS NMR has been performed in situ to investigate the activation of 13C labeled propane under a mild condition over Ga-modified H-ZSM-5 catalysts prepared via different methods. The results indicate that the ion-exchanged and/or its related Ga species are the highly active catalytic components, while impregnated Ga species is not the active species for propane activation at 573 K.
