Abstract
In this work, we proposed an improved wet-chemical method to synthesize Platinum (Pt) nanoparticles supported on the mesoporous carbon (FDU-15). A well-dispersed Pt precursor in FDU-15 was first received by using a CH2Cl2 solvent process and a simple melt-diffusion strategy. After the Pt precursor was reduced by formic acid without surfactant, almost 100% Pt nanoparticles were confined in the channels of FDU-15 (denoted as Pt/FDU-15). Physical (XRD, HRTEM and BET) and electrochemical (Cyclic voltammetry, COad stripping and chronoamperometry) methods were used to investigate the properties of Pt/FDU-15. Compared with the commercial catalyst Pt/C, the Pt/FDU-15 catalyst exhibits a much higher electrocatalytic activity toward CO and methanol oxidation. The origins of the high electrocatalytic activity of the Pt/FDU-15 were discussed.
