In general, preparation of composite membrane includes the introducing functional groups to PVDF membrane for adsorbing metal ions, and reducing the absorbed metal ions into metal NPs [18], Although several composite membranes have been reported [13, 17, 18], these composite membranes cannot separate the product from reactants because the formed metal NPs distributed both on membrane surface and in membrane pores results in the product always companied by the reactant in the whole process.
