摘      要：A hollow-fiber-supported stable Au/FAU catalytic membrane was successfully synthesized through a polydopamine coating modification-removal strategy and used as a flow-through catalytic membrane reactor for preferential oxidation of *** Au nanoparticles can be efficiently isolated by dopamine and the dopamine-derived carbon *** interactions between Au nanoparticles and zeolite layer support are enhanced during annealing at high temperature under an inert atmosphere.A zeolite membrane supported Au nanoparticle catalyst was obtained after the removal of carbon shells,which showed high catalytic activity and stability for the removal of CO from hydrogen.
