The recent study enlightens the synthesis and characterization of zirconia (ZrO 2 ), Fe-doped ZrO 2 (Fe@ZrO 2 ), and Ni-doped ZrO 2 (Ni@ZrO 2 ) catalysts having new-fangled morphology with tuned band gap as photocatalysts for degradation of textile wastewater dyes methylene blue (MB), malachite green (MG), and their mixtures. SEM imaging of Fe@ZrO 2 and Ni@ZrO 2 is interestingly varied from ZrO 2 as well as doping of transition metals greatly affects the morphology of composites. The optimization study depicts that the pH, time (min) and catalyst amount (g) have a direct relation with degradation efficiency, while the dye concentration (mg/L) has an indirect relation as well. The photocatalytic studies depict that the degradation of MB and MG follows oxidation pathway via hydroxyl radicals (OH • ) and holes. Reusability of catalysts corresponds to a little decrease in degradation efficiency in the first two cycles and decreases to about $10% (Ni@ZrO 2 ) and $12% (Fe@ZrO 2 ) in next three cycles.

BackgroundMetal–Organic Frameworks (MOFs) have emerged as promising materials for next‐generation batteries due to their unique properties such as high surface area, tuneable pore size, and composition.ObjectiveThis review explored the comprehensive summary of MOF‐based electrode materials, their synthetic ways and applications for batteries.MethodsFor example, solvothermal synthesis is commonly used for generating large MOF crystals, while hydrothermal synthesis is often used for synthesizing highly porous MOFs for energy storage devices. Herein, the synthetic strategies and applications of MOFs and their composites in batteries and supercapacitors are introduced.ResultsOur findings demonstrate that MOFs have the potential to revolutionize the field of batteries and open new possibilities for designing next‐generation batteries with improved performance and safety.ConclusionHowever, further research is needed to overcome the challenges and fully realize the potential of MOFs in batteries and it will contribute to forward advancement of pristine MOFs with excellent electrochemical behavior.
