摘要: Abstract This paper describes an investigation on catalytic properties of Pt nanoparticles supported MgAl(Sn)Ox mixed oxide for cyclohexane dehydrogenation to cyclohexene. The supports were synthesized by microwave calcined hydrotalcite-derived precursors, and Pt/MgAl(Sn)Ox catalysts prepared incipient wetness impregnation method. characterized X-ray diffraction (XRD), hydrogen temperature-programmed reduction (H2-TPR), desorption (H2-TPD), X-Ray photoelectron spectroscopy (XPS) transmission electron microscopy (TEM). results showed that the calcination changed interfacial character between support, strengthened interaction tin facilitated high dispersion presented support. These effects resulted in higher activity, stability cyclohexene selectivity
