This invention relates to catalysts, preparation methods, and applications for the one-pot catalytic oxidation of primary alcohols to esters using oxygen. The catalyst is a zinc-cobalt composite oxide, denoted as Zn-CoO, obtained by stepwise calcination of a Zn-doped modified ZIF-67 precursor. x The morphology is basically rhombic dodecahedral with a slightly concave surface, and the particle size is 0.8~1.2 μm. The primary alcohol as the reaction substrate is added to the reaction solvent, followed by the catalyst Zn-CoO. x The reaction involves the use of N-hydroxyphthalimide as a co-catalyst, with oxygen introduced into the solution during the reaction. The ester product is then separated after the reaction. This invention exhibits excellent catalytic performance for a variety of typical primary alcohols. The esterification yields are as follows: n-propanol oxidative esterification yield reaches 85.6%, n-butanol 97.0%, cyclohexylmethanol 89.9%, n-octanol 80.8%, and benzyl alcohol up to 96.0%. It demonstrates broad applicability and high selectivity for straight-chain aliphatic primary alcohols, cycloalkyl methanols, and aromatic primary alcohols.
