Abstract

Effects of carbonization temperature and time during carbon riveting process on the stability of Pt/C catalysts have been investigated systematically. X-ray diffraction, transmission electron microscopy, cyclic voltammograms, and accelerated potential cycling tests have been performed to characterize the catalysts. The experimental results show that the activity of the riveted Pt/C catalyst decreases with the increasing of the heat-treated temperature and the extension of heat-treated time due to sintering of Pt nanoparticles. The stability of the carbon riveted Pt/C catalysts exhibits the increasing trend with the increase of the carbonization time and temperature. Considering both of the activity and stability of the riveted Pt/C catalysts, the optimized carbonization temperature and time are 400°C and 60min for a Pt/VulcanXC-72 catalyst with starting particle size before carbonization of 2.2nm and 20wt% platinum loading, respectively.
