Biomass-derived activated carbon as high-performance non-precious electrocatalyst for oxygen reduction
Wang, Keliang; Wang, Hui; Ji, Shan; Feng, Hanqing; Linkov, Vladimir; Wang, Rongfang (Royal Society of Chemistry, 2013)A new type of Fe and N doped carbon material is synthesized by pyrolyzing ferric chloride doped egg white (EW) and the proposed synthetic route is easy, green, and low-cost. In addition, the as-prepared sample exhibits ... -
Ethanol oxidation activity and structure of carbon-supported Pt-modified PdSn-SnO2 influenced by different stabilizers
Wang, Hui; Liu, Ziyue; Ji, Shan; Wang, Keliang; Zhou, Tianbao; Wang, Rongfang (Elsevier, 2013)PdSn-SnO2 nanoparticles supported on Vulcan XC-72 carbon were synthesized by chemical reduction in the presence of three different stabilizing agents: ethylene diamine tetra-acetic acid (EDTA), sodium citrate (Nacitrate) ... -
Nitrogen-doped carbon coated ZeO2 as a support to Pt nanoparticles in the oxygen reduction reaction
Wang, Rongfang; Wang, Keliang; Wang, Hui; Wang, Qizhao; Key, Julian; Linkov, Vladimir; Ji, Shan (Elsevier, 2013)A new nitrogen-doped carbon (CNx) support for Pt electrocatalysts was prepared by carbonizing polypyrrole on the surface of ZrO2 (ZrO2@CNx) at high temperature. Well-dispersed Pt nanoparticles were easily formed on the ... -
Palygorskite hybridized carbon nanocomposite as a high-performance electrocatalyst support for formic acid oxidation
Linkov, Vladimir; Ji, Shan; Wang, Keliang; Wang, Hui; Wang, Rongfang; Key, Julian (South African Chemical Institute (SACI), 2013)A nanocomposite, in which acid-treated palygorskite was hybridized with carbon, was prepared and designed as an efficient support for electrocatatlysts. Pd nanoparticles were deposited on the hybrid support as an ...
