The catalytic activities of supported Pt-based bimetallic catalysts (Pt-M) were studied for hydrogen production via aqueous phase reforming (APR) using a 10 wt% ethylene glycol solution. The catalysts and supports used were characterized via X-ray powder diffraction (XRD), transmission electron microscopy (TEM), nitrogen adsorption-desorption, CO chemisorption, and temperature programmed reduction (TPR) techniques. It was found that the Pt-Mn (Pt:Mn = 1:1, molar ratio) bimetallic catalyst significantly enhanced the catalytic performances such as the hydrogen yield and hydrogen production when compared with monometallic catalysts and other bimetallic catalysts that were examined. The XRD and TPR studies confirmed the interaction between the Pt and Mn species, leading to the Pt-Mn alloys supported on CMK-3. Related to the effect of the type of support, the CMK-3 support demonstrated better performance than the commercial activated carbon and alumina. Accordingly, it can be understood that the better catalytic performance of the APR reaction over Pt-Mn/CMK-3 catalyst is dependent on the alloy effect as well as the structural properties and nature of support given by the addition of the second metal.
