摘要：

In this study, the influence of incorporating Co, Mo and Mn oxides into Pt/Al2O3 catalyst on the dehydrogenation performance of Liquid organic Hydrogen Carrier (LOHCs) is investigated. A notable positive impact on the dehydrogenation process was observed, resulting in enhanced catalytic performance. This effect is associated with improved product desorption and a significant reduction in the by-product formation like methylfluorene. Particularly, the electron-acceptor effect exhibited by molybdenum, emerge as the key factor in enhancing catalytic performance. This effect allowed for the reduction of platinum content without compromising the productivity and selectivity and representing a significant advancement in catalyst design. These findings highlight the potential for Mo-based catalysts to serve as a promising alternatives to Pt-based catalysts in LOHC dehydrogenation processes.
