An Fe@Fe3C-inserted carbon nanotube/graphite composite supportproviding highly dispersed Pt nanoparticles for ethanol oxidation
Wang, Rongfang; Key, Julian (Elsevier, 2014)Iron/iron carbide-inserted carbon nanotube/graphite composite (Fe-C) was prepared by pyrolyzing amixture of melamine and iron (III) chloride to form a support for high loading of Pt nanoparticles as adirect ethanol fuel ... -
Graphite-anchored lithium vanadium oxide as anode of lithium ion battery
Yi, Jin; Key, Julian; Wang, Fei; Wang, Yonggang; Wang, Congxiao (Elsevier, 2013)Graphite-anchored lithium vanadium oxide (Li1.1V0.9O2) has been synthesized via a “one-pot” in situ method. The effects of the synthesis conditions, such as the ratio of reaction components and calcination temperature, ... -
Nanoparticulate TiO2-promoted PtRu/C catalyst for methanol oxidation: TiO2 nanoparticles promoted PtRu/C catalyst for MOR
Wang, Wei; Wang, Hui; Key, Julian; Linkov, Vladimir; Ji, Shan; Wang, Rongfang (Springer, 2013)To improve the electrocatalytic properties of PtRu/C in methanol electrooxidation, nanoparticulate TiO2-promoted PtRu/C catalysts were prepared by directly mixing TiO2 nanoparticles with PtRu/C. Using cyclic voltammetry, ... -
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 ...
