“…BN membranes can be created by exfoliating bulk BN into thin layers or by synthesizing them through chemical vapor deposition (CVD) techniques. These membranes exhibit high water permeability while maintaining excellent selectivity, making them suitable for water desalination and filtration [90][91][92][93][94][95]. Numerous studies have been conducted to date that suggests the BN and its hybrid membrane are effectively used for oil-water separation.…”

Oil leakage and organic solvent industrial accidents harm the ecosystem, especially aquatic and marine life. Oil–water separation is required to combat this issue, which substantially enhances the ecosystem and recovery of oils from water bodies. In this aspect, significant efforts have been made by scientists to develop newer composite materials that efficiently separate oils from water bodies with exceptional recyclability. Membrane filtration is an efficient option for oil–water separation due to its ability to separate oil from water without involving any chemicals. However, relatively less water permeability and a high degree of surface fouling limit their applicability. The advent of two-dimensional nanomaterials (2D-NMs) gives newer insight in developing membranes due to their exceptional characteristics like hydrophobicity/hydrophilicity, selectivity, antifouling ability, flexibility, and stability. Incorporating 2D-NMs within the polymeric membranes makes them exceptional candidates for removing oil from water. Moreover, 2D-NMs offer rapid sorption/desorption rates and boost water transportation. Additionally, 2D-NMs provide roughness that significantly enhances the fouling resistance in the polymeric membrane. This review focuses on properties of 2D-NM-based polymeric membrane and their roles in oil–water separation. We also discussed strategies to improve the oil–water separation efficiency. Finally, we discussed oil–water separation’s outlook and prospects using 2D-NM-based polymeric membranes. This review might provide new insight to the researchers who work on oil–water separation.

SO 2 and NH 3 are toxic compounds and are the main sources of airborne molecular contaminants (AMCs). Even at low concentrations, they can cause equipment corrosion and reduce product yield. Therefore, it is crucial to develop a combined SO 2 and NH 3 capture material with a simple process and a high adsorption capacity. In this study, dynamic adsorption breakthrough experiments were conducted at 23 °C under an air pollutant concentration of 90 ppm. The synergistic adsorption results showed that Cu/AC-0.05 had a high adsorption capacity of 1.03 mmol of SO 2 /g and 1.45 mmol of NH 3 /g. Furthermore, to confirm the rationality of the modification method, characterization methods such as BET, SEM-EDX, XRD, and TG-DSC were used to study the new adsorbent and spent adsorbent. The results showed that copper was successfully attached to the activated carbon and distributed uniformly. In this study, efficient coremoval performance of SO 2 and NH 3 was achieved by modifying single metal active sites. Through a comprehensive analysis of the characterization results, the surface reaction mechanism of SO 2 and NH 3 on the prepared material was further determined. This work provides a feasible option for a highly efficient adsorbent for both SO 2 and NH 3 capture at low concentrations under room temperature.

Water polluted by toxic chemicals due to waste from chemical/pharmaceuticals and harmful microbes such as E. Coli bacteria causes several fatal diseases; and therefore, water filtration is crucial for accessing clean and safe water necessary for good health. Conventional water filtration technologies include activated carbon filters, reverse osmosis, and ultrafiltration. However, they face several challenges, including high energy consumption, fouling, limited selectivity, inefficiencies in removing certain contaminants, dimensional control of pores, and structural/chemical changes at higher thermal conditions and upon prolonged usage of water filter. Recently, the advent of 2D materials such as graphene, BN, MoS2, MXenes, and so on opens new avenues for advanced water filtration systems. This review delves into the nanoarchitectonics of 2D materials for water filtration applications. The current state of water filtration technologies is explored, the inherent challenges they face are outlines, and the unique properties and advantages of 2D materials are highlighted. Furthermore, the scope of this review is discussed, which encompasses the synthesis, characterization, and application of various 2D materials in water filtration, providing insights into future research directions and potential industrial applications.
