were also studied. The results show that lower open circuit potential and current efficiency, higher whiteness, better coating binding force were found when the substrate was nickel; when palladium......
) especially platinum, palladium and rhodium. The price of these metals and their increasing demand are the reasons why today it is necessary to recycle used auto catalytic converters. There are many......
, prior to the immersion in the industrial plating baths, the chemical reduction of the Pd+2 species (species covalently tethered on the nitrogen-containing groups) to metallic palladium (PdO) is shown......
fabricated by deposition of carbon nanotubes on top of the Y2 O3 films and formation of palladium contacts by a lift-off procedure. An on/off ratio of more than 4 orders of magnitude is achieved without......

Enhanced separation of Pd(Ⅱ) and Pt(Ⅳ) from hydrochloric acid aqueous solution using 2-((2-methoxyethyl)thio)-1H-benzimidazoleShao-Ping Feng1,2,Kun Huang11. School of Metallurgical and Ecological Engineering,University of Science and Technology Beijing2. Department of Chemistry,College of Science,Honghe University摘 要:Separation of palladium(Pd......
. These improvements are probably due to an increase in the surface roughness of polyimide (PI), the activated surface condition, and the adsorption of palladium ions/atoms (Pd) on the PI surface which act......
strength is 398MPa and the hermeticity is less than 1×10-8 Pa·m3/s. The electroless nickel was processed by utilizing palladium chloride as activator. The plating layer with bright, smooth......
of Na2S2O5. At the same time, gold, platinum and palladium were also captured. In order to determine the optimum process parameters, three main effect factors were investigated by an orthogonal......
and other base metals [15], palladium and platinum [16] extraction from chloride media. Hence, it seems that gold extraction may interface with other metal species extraction. The aim of the present work...) were used for platinum, palladium, selenium and iron sources in aqueous solution, respectively. Selenium source was prepared by SeO2 dissolution in dilute hydrochloric acid solution. Analytical......
