Metal-organic frameworks for photocatalytic detoxification of chromium and uranium in water

Photo-induced removal of uranium under air without external photocatalysts

“…By combining with the adsorption method, this strategy could dramatically enhance the extraction capacity of the adsorbent by breaking the adsorption equilibrium and regenerating the adsorption sites. 3 Many photocatalysts have been developed for this process, such as TiO 2 , 4-6 C 3 N 4 , [7][8][9] MOFs, 10,11 and COFs. [11][12][13][14] However, the photoreduction mechanism cannot work well under air.…”

Recent Progress in the Development of MOF-Based Photocatalysts for the Photoreduction of Cr(VI)

“…They are generally discharged into the environment by way of some industrial activities, for instance, metal polishing, electroplating, leather tanning, printing, and wood preservation . Cr (VI) , as a highly toxic ion with high solubility in water, causes numerous diseases such as diarrhea, genetic defects, allergic reactions, kidney failure, and different organ cancers. , The chemical reduction of Cr (VI) to less toxic Cr (III) , with low solubility in water (easy precipitation from the liquid phase), has been introduced as an urgent strategy to avoid further harm to the environment . Among chemical processes, photocatalysis reduction has received great attention because of high efficiency, low cost, simple installation, and environmental friendliness (e.g., utilization of solar energy, low energy consumption, low secondary pollution risk, low dosage of chemical reagents, zero sludge) .…”

Multi-functional metal–organic frameworks for detection and removal of water pollutions

“…[41][42][43][44] MOFs also demonstrate huge potential in water treatment field and a number of articles and reviews are reported. [45][46][47] However, most studies mainly focus on one function, namely, sensing, removal or degradation for water pollution disposal. Synthesizing functional MOFs with multiple processing to a certain pollutant is of great significance to detect and eliminate water pollutions on one platform.…”
