Abstract:The colloidal synthesis of metal oxide nanocrystals (NCs) in oleyl alcohol requires the metal to
catalyze an esterification reaction with oleic acid to produce oleyl oleate ester and M-OH
monomers, which then condense to form MxOy solids. Here we show that the synthesis of Cu2O
NCs by this method is limited by the catalytic ability of copper to drive esterification and thus
produce Cu+
-OH monomers. However, inclusion of 1-15 mol% of a group 13 cation (Al3+, Ga3+
,
or In3+) results in increased yields for the … Show more
