  • CNx-modified Fe3O4 as Pt nanoparticle support for the oxygen reduction reaction 

    Wang, Rongfang; Jia, Jingchun; Wang, Hui; Wang, Qizhao; Ji, Shan; Tian, Zhongqun (Springer, 2013)
    A novel electrocatalyst support material, nitrogendoped carbon (CNx)-modified Fe3O4 (Fe3O4-CNx), was synthesized through carbonizing a polypyrrole-Fe3O4 hybridized precursor. Subsequently, Fe3O4-CNx-supported Pt (Pt/Fe3O4-CNx) ...
  • Components for PEM fuel cells: An overview 

    Sivakumar, Pasupathi; Maiyalagan, Thandavarayan (Trans Tech Publications, 2010)
    Fuel cells, as devices for direct conversion of the chemical energy of a fuel into electricity by electrochemical reactions, are among the key enabling technologies for the transition to a hydrogen-based economy. Among ...
  • Effect of the structure of Ni nanoparticles on the electrocatalytic activity of Ni@Pd/C for formic acid oxidation 

    Wang, Rongfang; Wang, Hui; Wang, Xingli; Liao, Shijun; Linkov, Vladimir; Ji, Shan (Elsevier, 2013)
    Ni@Pd/C catalysts were synthesized, using Ni/C with different crystalline structures prepared with various ligands. A series of characterizations were performed by transmission electron microscopy, X-ray diffraction, X-ray ...
  • Effects of heat treatment on the catalytic activity and methanol tolerance of carbon-supported platinum alloys 

    Valisi, Andiswa; Maiyalagan, Thandavarayan; Khotseng, Lindiwe; Linkov, Vladimir; Pasupathi, Sivakumar (Springer, 2012)
    This work studies the effect of heat treatment of carbon-dispersed platinum and platinum alloys on its methanol tolerance and catalytic activity as gas diffusion electrodes for oxygen reduction reaction (ORR) in acid medium. ...
  • Montmorillonite modified by CNx supported Pt for methanol oxidation 

    Wang, Rongfang; Zhou, Tianbao; Qiu, Xiaoli; Wang, Hui; Wang, Qizhao; Feng, Hanqing; Linkov, Vladimir; Ji, Shan (Elsevier, 2013)
    A composite support based on nature clay, i.e. montmorillonite (MMT), shows great promise as support materials for Pt electrocatalyst for the methanol oxidation reaction in fuel cell anodes. The reported composite support ...
