Direct PtSn Alloy Formation by Pt Electrodeposition on Sn Surface

Dehydrogenation of Isobutane Over Nanoparticles of Pt/Sn Alloy on Pt/Sn/Na-Y Catalyst: The Effect of Tin Precursor on the Catalyst Behavior

In this research Na-Y was synthesized by hydrothermal method and used as support for preparation of Sn/Pt/Na-Y catalysts using two different tin precursors, Bu3Sn(Cl) and SnCl2.2H2O, by sequential impregnation, in which the Pt  was deposited first and in the next step Sn was deposited. The catalysts were characterized by H2 chemisorption, transmis...

Direct Electrodeposition of Polypyrrole on Aluminum and Aluminum Alloy by Electron Transfer Mediation

Adsorption and reaction of acetaldehyde on Pt(111) and Sn/Pt(111) surface alloys

Adsorption and reaction of acetaldehyde (CH3CHO) on Pt(1 1 1) and two ordered Pt–Sn alloys has been studied primarily by using temperature-programmed desorption (TPD) mass spectrometry and high-resolution electron-energy loss spectroscopy (HREELS). The two alloys investigated were the (2 · 2) and ( p 3 p3)R30 Sn/Pt(1 1 1) surface alloys with hSn 1⁄4 0:25 and hSn 1⁄4 0:33, respectively, as-prepa...

Electrodeposition and Characterization of Sn-Zn Alloy Coatings from Sulfate Based Baths

Tin-Zinc alloy coatings have many applications because of their unique properties such as corrosion resistance, solderability and flexibility. In this study, the effect of current density, temperature and pH on chemical composition, cathodic current efficiency, morphology and structures of the coatings was investigated. The results illustrated that, at low current densities (<0.5 mA/cm2), the c...
