Abstract

Pt/TiC, Pt/TiO ₂-TiC, and Pt/MWCNTs@TiO ₂-TiC catalysts have been synthesized by the microwave-assisted polyol process. Moreover, carbon riveted Pt/MWCNTs@TiO ₂-TiC catalyst based on in situ carbonization of glucose has also been prepared. X-ray diffraction, energy dispersive analysis of X-ray, transmission electron microscopy, X-ray photoelectron spectroscopy, cyclic voltammograms, and accelerated potential cycling tests have been used to characterize the catalysts. Experimental results show that both of the activity and stability of Pt/TiC catalyst cannot meet the requirements of proton exchange membrane fuel cells. In comparison with Pt/TiC, Pt/TiO ₂-TiC catalyst exhibits lower activity due to poor conductivity of TiO ₂ and higher stability ascribed to strong metal-support interaction (SMSI) between Pt and TiO ₂. However, compared with Pt/TiC, Pt/MWCNTs@TiO ₂-TiC catalyst exhibits both higher activity and stability because of high electrical conductivity of the mixed support and SMSI between Pt nanoparticles and nanocapsule composite MWCNTs@TiO ₂. Furthermore, the measurement results show that carbon riveted Pt/MWCNTs@TiO ₂-TiC catalyst with similar activity to the Pt/C and Pt/TiO ₂-C ones possesses 8.5 times stability as high as that of Pt/C and exhibits 4.5 times life-span as long as that of carbon riveted Pt/TiO ₂-C reported in our previous study.
