| 英文摘要 | sn-doped tio2 nanoparticles with high surface area of 125.7 m(2).g(-1) are synthesized via a simple one-step hydrothermal method and explored as the cathode catalyst support for proton exchange membrane fuel cells. the synthesized support materials are studied by x-ray diffraction analysis, energy dispersive x-ray spectroscopy and transmission electron microscopy. it is found that the conductivity has been greatly improved by the addition of 30 mol% sn and pt nanoparticles are well dispersed on ti0.7sn0.3o2 support with an average size of 2.44 nm. electrochemical studies show that the ti0.7sn0.3o2 nanoparticles have excellent electrochemical stability under a high potential compared to vulcan xc-72. the as-synthesized pt/ti0.7sn0.3o2 exhibits high and stable electrocatalytic activity for the oxygen reduction reaction. the pt/ti0.7sn0.3o2 catalyst reserves most of its electrochemically active surface area (eca), and its half wave potential difference is 11 mv, which is lower than that of pt/xc-72 (36 mv) under 10 h potential hold at 1.4 v vs. nhe. in addition, the eca degradation of pt/ti0.7sn0.3o2 is 1.9 times lower than commercial pt/xc-72 under 500 potential cycles between 0.6 v and 1.2 v vs. nhe. therefore, the as synthesized pt/tio3sn0.3o2 can be considered as a promising alternative cathode catalyst for proton exchange membrane fuel cells. |
