Preparation method for Fe and Cu bi-metal loading mesoporous carbon and alumina composite ceramic membrane material, and application of ceramic membrane material

The invention relates to a preparation method for a Fe and Cu bi-metal loading mesoporous carbon and alumina composite ceramic membrane material, and the application of the ceramic membrane material.An aluminium oxide hollow ceramic tube is dried in a drying oven; the Fe(NO3)3.9H2O and the Cu(NO3)2.3H2O of a mesoporous carbon precursor are added to be dissolved in absolute ethyl alcohol, mixtureis heated in a water bath and dripped into the ethanol solution of the mesoporous carbon precursor; the mixture is poured into watch glass and is evaporated at a room temperature to obtain a thick Feand Cu mesoporous material; two ends of a pre-prepared aluminium oxide ceramic tube carrier are blocked, and the thick Fe and Cu mesoporous material is smeared to the outer surface of the aluminium oxide ceramic tube carrier; rotary curing is carried out to obtain an even membrane layer; the ceramic tube membrane is dried in vacuum to obtain the Fe and Cu bi-metal loading mesoporous carbon and alumina composite ceramic memb
