In the present work, we studied catalytic performance (activity and selectivity) of Pt supported on carbon systems modified with tin in glycerol oxidation H2O2 as oxidising agent at atmospheric pressure, 60 °C, base-free conditions. The conversion obtained monometallic catalyst was 37% remained unchanged addition Sn a ratio Sn/Pt = 0.4. two bimetallic PtSn catalysts were able to oxidise commerc...

Eight bis(salicylaldiminato)tin(II) complexes have been synthesized from the reaction of Sn[N(SiMe(3))(2)](2) and 2 equiv of the corresponding ligands at room temperature. The ligands, synthesized from salicylaldehyde and amines, were designed to have different electronic and steric properties using different amines to synthesize the tin(II) complexes as aniline (2a), 2,6-dimethylaniline (2b), ...

UNLABELLED BACKGROUND The work aims at improving photocatalytic activity of titania under Vis light irradiation using modification by Sn ions and an original, simple synthesis method. Tin-doped titania catalysts were prepared by thermal hydrolysis of aqueous solutions of titanium peroxo-complexes in the presence of SnCl4 or SnCl2 using an original, proprietary "one pot" synthesis not employi...

Structure, morphology and composition of different tin oxide and germanium oxide thin film catalysts for the methanol steam reforming (MSR) reaction have been studied by a combination of (High-resolution) Transmission Electron Microscopy, Selected Area Electron Diffraction, Darkfield imaging and Electron Energy-Loss Spectroscopy. Deposition of the thin films on NaCl(001) cleavage faces has been...
