Abstract
In the present study, MgAl2O4 carriers were synthesized by the alcohol-heating method, and the effects of Pt loading and Pt/Pd molar ratio on decalin dehydrogenation activity were investigated systematically. The results showed that the size of Pt nanoparticle in the Pt/MgAl2O4 catalysts was closely related to the Pt loading and the optimum Pt loading was 3 wt% in the decalin dehydrogenation. The PtPd bimetallic catalyst with a Pt/Pd molar ratio of 4:1 generated moderate interactions and enhanced the catalytic performance. The superior catalytic performance of the 1 wt% Pt4Pd1/MgAl2O4 catalyst was mainly due to the synergistic effect of bimetallic Pt–Pd nanoparticles.
