Abstract: A mesoporous cerium oxide nano-material and a preparation method and an application thereof are provided in the present disclosure, belonging to the technical field of porous materials. The preparation method includes the following steps: using porous organic frameworks material as a templating agent, impregnating and adsorbing cerium salt precursor under an action of alkali, and removing the templating agent by roasting pyrolysis to obtain the mesoporous cerium oxide nano-material. POFs is carbonized into mesoporous carbon materials by calcination in inert atmosphere, which supports the mesoporous channels of cerium oxide, and then the carbonized carbon materials of POFs are removed by calcination in air atmosphere, forming the mesoporous structure of cerium oxide. The mesoporous cerium oxide nano-material prepared by the present disclosure has a high specific surface area and mesoporous structure, and is used as a catalytic material or catalyst carrier.

Abstract: 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.
