Природа биметаллических наночастиц, образующихся при взаимодействии ацетилацетонатных предшественников, нанесенных на поверхность Al[2]O[3]

Abstract

The efficiency of the supported systems is determined by both the nature of the support and by the method of preparation. A key factor for producing a highly active and selective catalyst is the method for metal deposition. The decomposition of metal-organic precursors is a good method for deposition of metal nanoparticles with a very small size and narrow size distribution on the surface of various supports. The supported systems were synthesized by the impregnation of [gamma]-Al[2]O[3] with a certain amount of Pd(acac)[2], Sn(acac)[2]Cl[2], Ga(acac)[3] dissolved in toluene with subsequent the thermal decomposition and oxidationreduction treatments of adsorbed acetylacetoneates precursors.
