    Advancements in Oil-Water Separation: the Role of Molybdenum and Tungsten Disulfide as Cutting-Edge 2D Nanomaterials
    (Elsevier, 2025) Recepoglu, Yasar Kemal; Goren, Ayseguel Yagmur
    This article reviews recent strides in synthesizing, functionalizing, and utilizing molybdenum disulfide (MoS2) and tungsten disulfide (WS2) nanomaterials owing to their exceptional wetting properties, which facilitate oilwater separation. Among various materials explored, they have also emerged as particularly promising candidates due to their high surface area, tunable surface chemistry, and unique layered structure. The twodimensional (2D) morphology offers abundant active sites, enhanced interaction with water molecules, and the ability to engineer surface wettability at the nanoscale, all of which are highly advantageous for efficient oilwater separation. Distinct separation mechanisms, performance benchmarks, and potential integration into practical separation setups were meticulously surveyed and analyzed. Furthermore, to elucidate the superiority of MoS2 and WS2 2D nanomaterials over alternative methodologies for oil-water separation, we comprehensively examined other techniques, including membrane processes, electrocoagulation, adsorption with modified materials, and biological methods. For instance, the high membrane, operational, and maintenance costs, scaling, fouling, expensive production steps, high energy consumption, and complex operations are significant limitations of other processes for oil-water separation. On the other hand, the MoS2 and WS2 nanomaterials provide sustainable and effective oil-water separation performance compared to other processes owing to their unique properties, such as superior reusability, high separation efficiency, excellent hydrophobicity (water-repelling) and oleophilicity (oil-attracting) features, significant chemical and thermal stability, and enhanced photocatalytic properties. This review showed that the oil-water separation efficiency of the MoS2 and WS2-based materials was 70-100 %. The highest oil-water separation efficiency of 100 % is observed using cellulose acetate -MoS2 fibrous sponge from a toluene-water mixture at a pH of 8. Nevertheless, while MoS2 and WS2 nanomaterials promise oil-water separation owing to their unique properties, their limitations, such as cost, scalability, environmental concerns, agglomeration, regeneration challenges, and potential toxicity, must be carefully addressed. Consequently, further research and development are necessary to overcome these hurdles and fully realize their potential in practical applications.

    The book focuses on Application of Nanotechnology in Membranes for Water Treatment but not only provides a series of innovative solutions for water reclamation through advanced membrane technology but also serves as a medium to promote international cooperation and networking for the development of advanced membrane technology for Universal well-being and to achieve the common goal of supplying economically, environmentally and societally sustainable freshwater and better sanitation systems. This book is unique because the chapters were authored by established researchers all around the globe based on their recent research findings. In addition, this book provides a holistic coverage of membrane development for water treatment, from the membrane preparation and characterizations to the performance for specific processes and applications. Since that water scarcity has become a global risk and one of the most serious challenges for the scientific community in this century, the publication of this book is therefore significant as it will serve as a medium for a good reference of an alternative solution in water reclamation. This book will provide the readers with a thorough understanding of the different available approaches for manufacturing membranes both with innovative polymeric systems and inorganic nano-materials which could give enhanced functionalities, catalytic and antimicrobial activities to improve the performance of the existing membranes. It will be useful for leading decision and policy makers, water sector representatives and administrators, policy makers from the governments, business leaders, business houses in water treatment, and engineers/ scientists from both industrialized and developing countries as well. © 2019 Elsevier B.V., All rights reserved.
