We have prepared a series of Mo/ZSM-5 systems by impregnation method with different metal loading. The optimum performance has been attained for 4% metal loading, yielding to ca. 2 mmol_benzene/g_cat at the end of the reaction. The obtained catalysts were widely structural and surface characterized. As Mo content increases, the surface feature of the support is affected specially its mesoporosity. It has been stated the enormous complexity of Mo species present in the studied system. In situ characterization by XPS reveals different reduction and carburization behaviour depending on the Mo content.

Mo / ZSM-5系统进行甲烷脱氢芳构化反应的结构和表面考虑

我们通过浸渍法制备了不同金属负载量的一系列Mo / ZSM-5系统。对于4％的金属负载，已经获得了最佳性能，屈服强度约为1。2毫摩尔_苯/克_猫在反应的末尾。所获得的催化剂具有广泛的结构和表面特征。随着钼含量的增加，载体的表面特征会特别影响其介孔性。已经指出，存在于研究系统中的Mo物种非常复杂。XPS的原位表征揭示了取决于Mo含量的不同还原和渗碳行为。
