Abstract

The development of an ideal membrane for membrane distillation (MD) is of the utmost importance. Enhancing the efficiency of MD by adding nanoparticles to or onto a membrane's surface has drawn considerable attention from the scientific community. It is crucial to thoroughly examine state-of-the-art nanomaterials-enabled MD membranes with desirable properties, as they greatly enhance the efficiency and reliability of the MD process. This, in turn, opens up opportunities for achieving a sustainable water-energy-environment nexus. By introducing carbon-based nanomaterials into the membrane's structure, the membrane gains excellent separation abilities, resistance to various feed waters, and a longer lifespan. Additionally, the use of carbon-based nanomaterials in MD has led to improved membrane performance characteristics such as increased permeability and a reduced fouling propensity. These nanomaterials have also enabled novel membrane capabilities like in situ foulant degradation and localized heat generation. Therefore, this review offers an overview of how the utilization of different carbon-based nanomaterials in membrane synthesis impacts the membrane characteristics, particularly the liquid entry pressure (LEP), hydrophobicity, porosity, and membrane permeability, as well as reduced fouling, thereby advancing the MD technology for water treatment processes. Furthermore, this review also discusses the development, challenges, and research opportunities that arise from these findings.

用于膜蒸馏的碳基纳米复合膜:进展、问题和未来展望》。
开发用于膜蒸馏(MD)的理想膜至关重要。通过在膜表面添加纳米颗粒来提高 MD 的效率已引起科学界的极大关注。彻底研究具有理想特性的最先进纳米材料支持 MD 膜至关重要,因为它们大大提高了 MD 过程的效率和可靠性。这反过来又为实现可持续的水-能源-环境关系提供了机会。通过在膜结构中引入碳基纳米材料,膜可获得出色的分离能力、对各种进水的耐受性以及更长的使用寿命。此外,在 MD 中使用碳基纳米材料还能改善膜的性能特征,如增加渗透性和降低污垢倾向。这些纳米材料还实现了新的膜功能,如原位污物降解和局部发热。因此,本综述概述了在膜合成中使用不同的碳基纳米材料如何影响膜特性,特别是液体进入压力(LEP)、疏水性、孔隙率和膜渗透性,以及如何减少污垢,从而推进水处理过程中的 MD 技术。此外,本综述还讨论了这些发现带来的发展、挑战和研究机会。
