A mini-review on MoS₂membrane for water desalination: Recent development and challenges

This review provides comprehensive studies of molybdenum disulfide (MoS2) for water desalination. The most recent molecular dynamics simulation and experimental work on the design, fabrication, ion rejection, and water flux of MoS2 were summarized. Since MoS2 has excellent properties such as physicochemical, mechanical, and biological properties compared to other 2D materials such as graphene-based nanomaterial, it is necessary to have a critical study on MoS2-based membranes. Hence, a critical review of MoS2-based membranes has been found essential for us to investigate and evaluate the findings in this field and objectively assess the current state-of-the-art in water desalination. The advantages of desalination technology and the primary approaches that have been used up until now are first outlined in this study, deeply emphasizing membrane technology. The primary mechanism of salt rejection in membrane technology is explained. Then, the types of MoS2-based membranes for water desalination are reviewed based on the different published works while critically reviewing the performance of each type of MoS2-based membranes.
