The Pt-loading properties of ordered mesoporous carbon (OMC) synthesized with assistance of MClx (M=Pd, Fe, Cr; x=2, 3, 3) were investigated. X-ray diffraction (XRD) and transmission electron microscope (TEM) show that the ordered structure is well-preserved after the introduction of PdCl2. Because of the pyrolysis of organic carbon the OMC-PdCl2 is mainly present in the formof metallic Pd and is homogenously embedded into the scaffold of the OMC. A binary catalyst comprised of metallic Pd and microwave-reduced Pt nanoparticles was also generated. Electrochemical hydrogen absorption-desorption tests reveal that Pt/OMC-MClx possesses excellent catalytic performance and has an electrochemical active surface area (SEA) being as 2-4 times as that of Pt/OMC. Pt/OMC-PdCl2 has the highest SEA of 120.2 m2·g-1 followed by Pt/OMC-CrCl3 and then Pt/OMC-FeCl3. After a long-term cyclic voltammetric test, Pt/OMC-MClx still exhibits excellent catalytic stability and relatively higher catalytic activity as evidenced by a 22%-40% decrease in catalytic activity after one hundred cycles. This work will open up a most promising application in catalysis.
