“…Two kinds of Sn 2+ species were formed: Sn 2+ (1) corresponds to a relatively 'bulky' SnO phase with isomer shift 2.77 mm/s and quadrupole splitting 2.56 mm/s. The Sn 2+ (2) species with isomer shift 3.19 mm/s and quadrupole splitting 2.05 mm/s refer to Sn-O-Al-like species [22].…”

“…Catalysis of hydrocarbon conversion over supported Pt-Re, Pt-Ir, Pt-Sn and Pt-Ge catalysts has been the subject of numerous patents and papers [1][2][3][4][5][6][7][8][9][10]. Those bimetallic systems offered improved activity and stability compared to their monometallic Pt/Al 2 O 3 predecessor.…”

“…Après la régénération, le catalyseur est réduit sous hydrogène avant de réaliser un nouveau cycle de travail. Les différentes études physiques (XPS, Môssbauer) réalisées sur des catalyseurs Pt -Sn / AI2O3 réduits montrent que l'étain est presque uniquement présent à l'état Sn 11 , en forte interaction avec l'alumine [5] [6][7]. L'étain est un promoteur de la Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jp4:1996492…”
