Summary: Metal-organic frameworks (MOFs) derived metal oxides/porous carbon nanocomposites were used as efficient adsorbents to remove pollutants from wastewater. By introducing functional groups, the adsorption performance of the nanocomposites was significantly improved. This study focused on the preparation and testing of hydroxyl-modified zirconia/porous carbon nanocomposite (C-UiO-66-OH) as an adsorbent for the typical pollutant carbamazepine (CBZ). The results showed that C-UiO-66-OH had a much higher adsorption capacity compared to normal UiO-66, and the adsorption process was spontaneous and endothermic. The adsorbent could be easily regenerated using ethanol and DI water. Additionally, a membrane prepared by immobilizing C-UiO-66-OH into melamine foam with sodium alginate exhibited excellent removal efficiency and good regeneration for CBZ adsorption.

Summary: The material for managing and monitoring waste made from the waste itself is an excellent example of cyclic utilization, which could reduce issues and be more sustainable. The researchers synthesized a three-dimensional porous uranyl phosphonate MOF (UPF-105) through a hydrothermal method. UPF-105 exhibited stability in aqueous solution within the pH range of 1-11 and maintained crystallinity below 215 degrees C. The uncoordinated phosphonate groups in the channels of UPF-105 acted as functional anchors for selectively capturing uranyl ions, with a maximum uranium adsorption capacity of 170.23 mg g(-1). The fluorescence of UPF-105 made it a good candidate for a uranyl ion sensor in uranium-contaminated solutions with concentrations in the range of 5-90 ppm.
