Paragraph starter
The development of Metal-Organic Framework (MOF)-based mixed matrix membranes (MMMs) offers a promising avenue for efficient resource recovery. Research by Nour et al. (2024) demonstrated that incorporating MOFs like MIL-53(Al) into polyethersulfone membranes significantly enhanced the removal of nickel and cobalt ions from aqueous solutions, achieving up to 95% efficiency. This highlights the potential of tailored composite materials to address critical resource shortages in sectors such as electric vehicle battery production.
