Safe drinking water for all is a major challenge and needs critical attention, as freshwater aquifers are rapidly declining. A strategy based on addressing scarcity through membrane‐based purification and desalination can be an immediate and robust solution. The current scientific advances toward tailoring the structure and chemical properties of existing membrane materials have enabled key insights leading to new water purification alternatives. In the first part of the article, the key requirements for water decontamination addressed through state‐of‐the‐art literature on membranes are discussed. In the next part, the specific membrane modification strategies to impede bacterial growth and enhance fouling resistance are discussed, bringing in the underlying mechanisms. Finally, promising next‐generation separation techniques that are inspired by nature, inorganic and carbonaceous nanomaterial‐based membranes, layer‐by‐layer assembly, and dynamic composite membranes, are highlighted. This perspective article will help guide researchers working in this field from both industrial and academic standpoints, especially where the research is focused toward developing strategies to modify the existing solution besides finding alternative and sustainable new materials.

In this study, the characteristics of different types of nanosheet membranes were reviewed in order to determine which possessed the optimum propensity for antifouling during water purification. Despite the tremendous amount of attention that nanosheets have received in recent years, their use to render membranes that are resistant to fouling has seldom been investigated. This work is the first to summarize the abilities of nanosheet membranes to alleviate the effect of organic and inorganic foulants during water treatment. In contrast to other publications, single nanosheets, or in combination with other nanomaterials, were considered to be nanostructures. Herein, a broad range of materials beyond graphene-based nanomaterials is discussed. The types of nanohybrid membranes considered in the present work include conventional mixed matrix membranes, stacked membranes, and thin-film nanocomposite membranes. These membranes combine the benefits of both inorganic and organic materials, and their respective drawbacks are addressed herein. The antifouling strategies of nanohybrid membranes were divided into passive and active categories. Nanosheets were employed in order to induce fouling resistance via increased hydrophilicity and photocatalysis. The antifouling properties that are displayed by two-dimensional (2D) nanocomposite membranes also are examined.

“…Pristine GO membranes exhibit poor structural stability in water due to undesirable redispersion of GO nanosheets decorated by oxygen‐containing groups . To stabilize the membrane structure, chemical crosslinking approach can be used, however, water permeance would be sharply decreased . Alternatively, reduction of GO was employed to remove the oxygen‐containing groups, thereby creating stronger π – π attraction between adjacent nanosheets in reduced GO (rGO) membrane .…”

Nanoparticles@rGO membrane enabling highly enhanced water permeability and structural stability with preserved selectivity

Developing advanced membranes with high separation performance and robust mechanical properties is critical to the current water crisis. Herein, a general and scalable fabrication of nanoparticles (NPs)@reduced graphene oxide (rGO) membranes with significantly expanded nanochannels meanwhile ordered laminar structures using in situ synthesized NPs@rGO nanosheets as building blocks is reported. Size‐ and density‐controllable NPs were uniformly grown on the regularly stacked rGO nanosheets through coordination, followed by filtration‐deposition on inner surface of porous ceramic tubes. The NPs bonded rGO building blocks enabled the as‐prepared membranes 1–2 orders of magnitudes higher water permeance than the counterparts while keeping excellent rejections for various organic matters and ions. Moreover, the industrially preferred GO‐based tubular membrane exhibited an extraordinary structural stability under high‐pressure and cross‐flow process of water purification, which is considered as a notable step toward realizing scalable GO‐based membranes. © 2017 American Institute of Chemical Engineers AIChE J, 2017
