摘要： The adsorption of methanol altered structures of Au–Pt bimetallic nanoclusters on a thin film of Al2O3/NiAl(100). Methanol adsorbed on the Au–Pt intermixed bimetallic clusters, of which the surfaces consist of both Au and Pt, induced a segregation of Au from Pt. This segregation state was unstable, as the clusters returned to the initial Au–Pt intermixed state upon desorption or decomposition of adsorbed methanol. Ethanol and cyclohexene were adsorbed on Au–Pt bimetallic clusters for comparisons, indicating that the interaction of the hydroxyl group of methanol with the clusters accounts for the structural modifications. ► Methanol on supported Au–Pt intermixed bimetallic clusters induced a segregation of Au from Pt. ► Ethanol and cyclohexene were adsorbed on Au–Pt bimetallic clusters for comparisons. ► The interaction of the hydroxyl group of methanol with the clusters accounts for the structural modifications. 出版者： Kidlington: Elsevier B.V 出版日期： 2012-08-01 出處： Surface science, 2012-08, Vol.606 (15-16), p.1173-1179 版權： 2012 Elsevier B.V. 版權： 2015 INIST-CNRS 識別號： ISSN: 0039-6028 識別號： EISSN: 1879-2758 識別號： DOI: 10.1016/j.susc.2012.03.015 識別號： CODEN: SUSCAS
