| Summary: | Special issue: Conference on Cluster Science and Nanotechnology; Nanjing, China, September 6-10, 2004; Lanzhou, China, September 12-15, 2004 The present work is devoted to the study of some properties (size, electronic state, redox properties, interaction with matrix) of gold clusters and nanosized particles in Na-Y zeolite modified by iron. Two methods of iron introduction were applied: wet-impregnation and ion-exchange, which result in different structure and reducibility of iron species. Aggregation of iron species and their probable dissolution during gold deposition in samples prepared by wet-impregnation permits to form new Au, Fe and Au-Fe species in contrast to samples prepared by ion-exchange. The strong interaction of Au with Fe species in Au/Feimp/NaY changes noticeably a behavior of gold nanoparticles under heating. В фонде НТБ ТПУ отсутствует |
