摘要：Graphene oxide (GO) laminate membranes for water purification have surged in popularity due to their hydrophilicity, high throughput and excellent separation abilities. However, concerns about swelling and stability in water persist. Herein, we prepared high stability, composite reduced graphene oxide (rGO)/graphene oxide (GO) membranes. The composite membranes (i.e. rGO/GO composite membranes) displayed excellent rejection performance for methylene blue (MB) of up to 99.0%, together with ultrahigh water permeance (201.7 L m-2 h-1 bar-1) compared to pristine GO membranes (54.8 L m-2 h-1 bar-1). This study broadens the applications of graphene-based membranes and enhances their performance in water treatment. The rGO/GO composite membranes displayed excellent rejection performance for dyes, together with ultrahigh water permeance.
