Over the past few decades, the disposal of various industrial pollutants such as organic dyes, heavy metal ions, pesticides, and phenolic compounds has led to the deterioration of the quality of freshwater; even with the 70% water coverage over the earth, there is meager access to freshwater sources. Against the drawbacks of conventional water purification methods such as sludge production and generation of toxic byproducts, the adsorption process is regarded as an efficient and economical strategy for the treatment of wastewater. Among various available adsorbents, cyclodextrin-based nanosponges have evolved as prominent adsorbents for treating wastewater and are considered a cost-effective option with minimal energy and time requirements. Owing to their porous nature, cone-like structure, cross-linked three-dimensional network, and special architecture of the hydrophilic and hydrophobic moieties wherein the hydrophobic core can form inclusion complexes with pollutants via host−guest interactions while hydrophilic edges interact with pollutants through hydrogen-bonding and electrostatic interactions, they are effective adsorbents for the removal of a variety of pollutants such as heavy metals, organic dyes, phenols, and pesticides. Additionally, the number of active sites in these nanosponges could be enhanced by hybridizing with other adsorbents or by functionalization with magnetic nanoparticles. This review deliberates various water purification methods and underlines the limitations of using other conventional methods over adsorption. The strategies to synthesize β-cyclodextrin-based nanosponges deploying various cross-linkers and their further modifications have been discussed in detail. Finally, the application of these nanosponges for the effective removal of assorted pollutants from wastewater highlighting the adsorption mechanism in certain cases is cogitated.

BACKGROUND Advanced oxidation technologies such as photocatalysis assisted by hydrogen peroxide (H2O2) are significantly more effective. Their synergy may greatly improve the degradation efficiency of pollutants with proper catalysts. In this study, a series of iron Metal organic framework/bismuth oxybromide (Fe‐MOF/BiOBr) catalysts were prepared, and their properties examined using Rhodamine B (RhB) as the target pollutant. Through comparison tests of photocatalysis and activating H2O2 under visible light‐initiated oxidation reaction, the catalyst, the degradation effect and reaction conditions were optimized. RESULTS All of the composites showed better photocatalysis performance than the pure BiOBr and Fe‐MOF, and the catalytic efficiency of a composite sample MB1 with 5 mg Fe‐MOF in BiOBr was the highest. When MB1 was applied to aheterogenous Fenton‐like reaction involving H2O2 and photocatalysis under visible light ([H2O2] = 10 mmol L–1), the capacity for degradation of RhB increased to 11.1 mg/(mg·min) whereas it was only 4 mg/(mg·min) by photocatalysis alone. In addition, the optimal reaction conditions were pH 5 and 50 W light. The mechanism study showed that 1 O2 and ·O2− were the main active species for pollutant degradation. CONCLUSION This study provides a new and highly efficient catalyst to heterogeneously activate H2O2 under visible light to degrade a pollutant. The developed Fe‐MOF/BiOBr combination has great application potential. © 2022 Society of Chemical Industry (SCI).
