Nonhydrolytic Synthesis and Electronic Structure of Ligand-Capped CeO2−δ and CeOCl Nanocrystals

A novel and versatile nonhydrolytic approach is developed for the synthesis of ligand-passivated CeO2−δ and CeOCl nanocrystals soluble in nonpolar organic solvents based on the condensation of cerium alkoxides with cerium halides. The alkyl group on the metal alkoxides and the specific halide used i...

Zusammenfassung:A novel and versatile nonhydrolytic approach is developed for the synthesis of ligand-passivated CeO2−δ and CeOCl nanocrystals soluble in nonpolar organic solvents based on the condensation of cerium alkoxides with cerium halides. The alkyl group on the metal alkoxides and the specific halide used in the synthesis are observed to considerably influence the composition and size of the obtained nanocrystals. The obtained nanocrystals are
