PtRu/carbon hybrid materials were prepared by hydrothermal carbonization using starch as carbon source and reducing agent and H2PtCl6.6H2O and RuCl3.xH2O as metal sources of the carbonization process. The materials were prepared in the following conditions: without pH adjustment, in the absence and in the presence of tetrapropylammonium chloride, and adjusting the pH using potassium hydroxide or tetrapropylammonium...
Pt/C, PtRu/C, PtBi/C, and PtRuBi/C electrocatalysts (20 wt.% metal loading) were prepared by borohydride reduction using H2PtCl6·6H2O, RuCl3·xH2O, and Bi(NO3)3·5H2O as metal sources and Vulcan XC 72 as support. The electrocatalysts were characterized by energy-dispersive X-ray analysis, X-ray diffraction, and thermogravimetric analysis. The electro-oxidation of ethanol was studied in sulfuric acid...
Neutron activation analysis has been applied to analyse ear piercing studs manufactured with three different types of metallic materials and also in the analyses of cell culture media in which these studs were immersed. Results obtained in these analyses indicated the release of metal from the studs to the culture media. Zn and Fe were found, respectively, in the extracts of gold coated copper-zinc...
