Amorphous Pt@dCu/CNT catalyst for methanol elextrooxidation
Wang, Hui; Ji, Shan; Wang, Wei; Wang, Rongfang (South African Chemical Institute (SACI), 2013)A multi-walled carbon nanotube-supported, Pt decorated nano-sized amorphous PdCu alloy cores (denoted as Pt@PdCu/CNT) catalyst with lower Pt loading is synthesized via a galvanic displacement reaction. The structure is ... -
Effect of ni core structure on the electrocatalytic activity of pt-ni/c in methanol oxidation.
Kang, Jian; Wang, Rongfang; Wang, Hui; Liao, Shijun; Key, Julian; Linkov, Vladimir; Ji, Shan (MDPI, 2013)Methanol oxidation catalysts comprising an outer Pt-shell with an inner Ni-core supported on carbon, (Pt-Ni/C), were prepared with either crystalline or amorphous Ni core structures. Structural comparisons of the two forms ... -
The effect of PtRuIr nanoparticle crystallinity in electrocatalytic methanol oxidation
Ma, Yanjiao; Wang, Rongfang; Wang, Hui; Liao, Shijun; Key, Julian; Linkov, Vladimir; Ji, Shan (MDPI, 2013)Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as ... -
Platinum overlaid PdCulr/C: an Improved Methanol Oxidation Elextrocatalyst
Ma, Yanjiao; Wang, Rongfang; Wang, Hui; Ji, Shan (ESG, 2013)A platinum overlaid PdCuIr/C (Pt-PdIrCu/C) anodic catalyst for direct methanol fuel cell was prepared by a two-step reduction method. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) results show that the ... -
Selectivity of oxygen evolution reaction on carbon cloth-supported δ-mno2 nanosheets in electrolysis of real seawater
Linkov, Vladimir; Ji, Shan; Yan, Haofeng; Wang, Xuyun; Wang, Rongfang (Molecules, 2023)Electrolysis of seawater using solar and wind energy is a promising technology for hydrogen production which is not affected by the shortage of freshwater resources. However, the competition of chlorine evolution reactions ... -
Selenium functionalized carbon for high dispersion of platinumeruthenium nanoparticles and its effect on the electrocatalytic oxidation of methanol
Wang, Rongfang; Da, Huahua; Wang, Hui; Ji, Shan; Tian, Zhongqun (Elsevier, 2013)Using selenium functionalized carbon as supports, platinumeruthenium nanoparticles were highly dispersed on the carbon surface, and showed improved electrochemical properties for methanol electrooxidation. The method ...
