Partially reduced graphene oxide/glass fiber composite membrane as well as preparation method and application thereof

The invention relates to the technical field of gas separation membranes, and provides a partially reduced graphene oxide/glass fiber composite membrane as well as a preparation method and application thereof. Filtering the ethanol dispersion liquid of graphene oxide to the surface of the glass fiber microfiltration membrane, and drying to obtain a graphene oxide/glass fiber composite membrane; carrying out heat treatment on the graphene oxide/glass fiber composite membrane to obtain a partially reduced graphene oxide/glass fiber composite membrane; the raw material utilization rate is high, the membrane preparation process is simple, and the prepared membrane is uniform and orderly stacked; through a partial reduction strategy, the synergistic effect of interlayer channel size screening and functional group interaction is fully exerted, and the H2/CO2 selectivity of the partially reduced graphene oxide/glass fiber composite membrane is greatly improved; after the catalyst is applied to a gas separation test,
