Microcystin-LR detection and removal in MOFs-based functional materials

Abstract

Harmful algae bloom in fresh lake water caused by Microcystis aeruginosa (M. aeruginosa) is of growing environmental concern. M. aeruginosa can release microcystin-LR (MC-LR) that exerts serious threat to human health and safety, which necessitate the advanced solutions for both MC-LR monitoring and elimination. Metal-organic frameworks (MOFs), as emerging environmental functional materials, have demonstrated exceptional potential as multifunctional platforms for MC-LR management. The large specific surface area, high porosity, and abundant active sites of MOFs are favorable for MC-LR adsorption Meanwhile, the semiconductor-like behaviors endow MOFs with high performances for efficient photocatalytic MC-LR degradation. Since there has been an increasing number of studies showing intensive attention to MC-LR prevention, recent progresses of MOFs-based materials for MC-LR detection and removal were reviewed, which highlighted the pivotal roles of MOFs in MC-LR sensors and the design principles of MOFs-based adsorbents/photocatalysts for MC-LR removal. Finally, the limitations, challenges and perspectives of MOFs-based materials for MC-LR prevention were proposed, aiming to provide essential reference values for future research.
