The reduced graphene oxide-gold nanoparticle (rGO-Au NP) membranes are prepared by vacuum filtration method. The sizes of the Au NPs on the surface of the rGO are about 8-10 nm, and the lattice spacing of Au NPs is 0.0241 nm, which is relative to the cubic lattice of the gold crystal. The layer-by-layer stacking structure of rGO-Au NP membrane can be observed clearly by field emission scanning electron microscopy. The water flux of the rGO-Au NP membrane is as high as 204.1 L m
−2 h−1 bar−1 , and its retention for Rhodamine B (RhB) is as high as 99.79%. [ABSTRACT FROM AUTHOR]- Published
