An immobilized enzyme Pickering emulsion reaction system and application thereof are provided, comprising immobilized enzymes with a mesoporous nanomaterial carrier, an oil phase and an aqueous phase for forming an emulsion, wherein the emulsion has a particle diameter of 10-80 m, which uses a reaction raw material as the oil phase, uses a butler solution as the aqueous phase, and uses the immobilized enzymes with the mesoporous nanomaterial carrier as both the catalyst and the emulsifier. Compared with conventional emulsions with additional organic reagents or emulsifiers, catalytic activity and stability the Pickering emulsion enzymatic reaction system of the present invention have been significantly improved. Products are easy to separate and purify, easy to reuse, and easy to scale up. The present invention has wider application scope, which is more conducive to environmental protection.
