One-pot organometallic synthesis of alumina-embedded Pd nanoparticles

Abstract

Herein we report a one pot organometallic strategy to access alumina-embedded Pd nanoparticles. Unexpectedly, the decomposition of the organometallic complex tris(dibenzylideneacetone)dipalladium(0), Pd2(dba)3, by dihydrogen in the presence of aluminum isopropoxide, Al(iPrO)3, and without extra stabilizers, was found to be an efficient method to generate a Pd colloidal solution. Careful characterization studies revealed that the so-obtained Pd nanoparticles were stabilized by an aluminum isopropoxide tetramer and 1,5-diphenyl-pentan-3-one, which was produced after reduction of the dba ligand from the organometallic precursor. Moreover, calcination of the obtained nanomaterial in air at 773 K for 2 h resulted in a nanocomposite material containing Pd nanoparticles embedded in Al2O3. This stabilization strategy opens new possibilities for the preparation of transition metal nanoparticles embedded in oxides.
