The present disclosure provides a preparation method of a mesoporous CeO2-loaded Au catalyst, products and applications thereof, and belongs to the technical field of fine organic chemical industry. According to the present disclosure, firstly, COFs material COFs-41 is employed to prepare mesoporous CeO2 carrier material with high specific surface area; then, Au nanoparticles loaded on the surface of mesoporous CeO2 carrier pores are anchored by impregnation-reduction method to produce Au@CeO2 catalyst with high specific surface area; and then, mesoporous Au@CeO2 catalyst with high specific surface area, aromatic alcohols are added to a reactor, anhydrous methanol is used as a solvent, and heating is carried out to react in an atmosphere of atmospheric oxygen for a certain period of time at room temperature, and this catalyst catalyzes the oxidative transesterification of aromatic alcohols for synthesis of aromatic esters in a highly selective manner.
A preparation method of a mesoporous CeO2-loaded Au catalyst, wherein the preparation method comprises using COFs-41 as a template and cerium nitrate as a cerium source, firstly loading Ce3+ by an impregnation method, then preparing a mesoporous CeO2 carrier material by oxidative roasting;
