Outline of Final Research Achievements |
Conventional impregnation methods are useful for preparing supported metal nanoparticles except small gold (Au) nanoparticles. We developed a novel simple and easy impregnation method using Au complexes coordinated with β-alanine as precursors. The chloride-free Au complexes were successful for the preparing small Au nanoparticles, which exhibited an average diameter less than 3 nm on the basis of TEM observations, on various supports including silica, which were difficult to be applied for conventional methods. Thermal behavior of the Au complex was investigated by thermogravimetry-differential thermal analyses and in situ X-ray absorption fine structure (XAFS). Lower decomposition and reduction temperature of the Au complex prevented Au atoms from aggregating and from following growth of Au particles. The prepared Au/SiO2 showed high selectivity for hydrogenation of 1-nitro-4-vinylbenzene into 1-ethyl-4-nitorobenzene.
