Abstract

X-ray diffraction and Mössbauer spectroscopy studies indicate that the thermal pretreatment of Pt−Sn catalysts supported on ZnAl2O4 and MgAl2O4 spinels, in the reduction medium leads to the formation of coarse-disperse particles of PtSn, Pt2Sn3 and PtSn2 alloys, which deactivate the catalysts.

Abstract

С помощьу методов рентгенографии и ЯГр спектроскопии установлено, что предварительная термообработка в восстановительной среде Pt−Sn катализаторов, нанесэнных на ZnAl2O2 и VgAl2O4 шпинели, приводит к образованию в них грубодисперсных частиц сплавов PtSn, Pt2Sn3 и PtSn2. В резулятате нроисходит дезактивация катализаторов.
