text: Ligands are a fundamental part of nanocrystals. They control and direct nanocrystal
syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’
chemical reactivity and electronic structure. Surface chemistry is thus crucial
to understand nanocrystal properties and functionality. Here, we investigate the
synthesis of metal oxide nanocrystals (CeO2-x, ZnO, and NiO) from metal nitrate
precursors, in the presence of oleylamine ligands. Surprisingly, the nanocrystals
are capped exclusively with a fatty acid instead of oleylamine. Analysis of the
reaction mixtures with nuclear magnetic resonance spectroscopy revealed several
reaction byproducts and intermediates that are common to the decomposition of
Ce, Zn, Ni, and Zr nitrate precursors. Our evidence supports the oxidation of
alkylamine and formation of a carboxylic acid, thus unraveling this counterintuitive
surface chemistry.
