“…To better assess the ability of degradation of shaddock peel/ZIF-8, we have compared our results with relevant reports using ZIF-8 composite-based nanomaterials as photocatalysts. Compared with other work, , under the condition of a similar degradation rate, the degradation time of MB by shaddock peel/ZIF-8 is greatly reduced. Because the preparation method of shaddock peel/ZIF-8 is simple, the raw materials are cheap and easy to obtain, and it shows that shaddock peel/ZIF-8 has a good prospect for dye photodegradation.…”

The development of water treatment materials using environmentally friendly natural biomasses as substitutes plays an increasingly important role in environmental protection. Zeolitic imidazolate framework-8 (ZIF-8) is often used for the catalytic degradation of dye wastewater, but due to its small particle size, its disadvantage of easy agglomeration prevents it from being fully functional. Herein, we report an efficient method for synthesizing biomasses/ZIF-8 using four different fruit peels as carriers. ZIF-8 nanoparticles are in-situ grown uniformly on their surface. The Brunauer–Emmett–Teller surface area of shaddock peel/ZIF-8 was found to be 752.15 m 2 g –1 . After catalytic activity comparison, the loose shaddock peel/ZIF-8 showed the fastest and most significant degradation efficiency of 94% in methylene blue aqueous solution and could be used multiple times through a simple washing process.

In this article, we present the synthesis of calcium sulfate nanoparticles (CaSO 4 NPs) from waste chalk powder by the calcination method. These CaSO 4 NPs were utilized for the construction of a mesoporous graphitic carbon nitride-calcium sulfate (mpg-C 3 N 4 -CaSO 4 ) photocatalyst. Synthesized materials were confirmed by several characterization techniques. The photocatalytic performance of the synthesized samples was tested by the degradation of methylene blue (MB) in the presence of both UV−vis light and sunlight. The efficiency of photocatalytic degradation of MB dye using the optimized mpg-C 3 N 4 -CaSO 4 -2 composite reached 91% within 90 min in the presence of UV−vis light with superb photostability and recyclability after five runs compared to individual mpg-C 3 N 4 and CaSO 4 NPs and reached 95% within 120 min under sunlight. Histotoxicological studies on fish liver and ovary indicated that the dye containing the solution damaged the structure of the liver and ovary tissues, whereas the photodegraded solution of MB was found to be less toxic and caused negligible alterations in their typical structure similar to the control group.

“…MOFs are always porous substances formed by metal ions interconnected to organic ligands via coordination bonds. − They exhibit excellent chemical stability, a large surface area, remarkable thermal robustness, and persistent porosity. MOFs and their derivatives have gained special interest for adsorption removal of malachite green (MG), Rhodamine B (RhB), methylene blue (MB), methyl orange (MO), and so on. , As reported previously, Ahmadijokani et al introduced UiO-66 MOF to selectively eliminate dyes of methyl red (MR), MG, MO, and MB.…”

Insights into High-Performance and Selective Elimination of Cationic Dye from Multicomponent Systems by Using Fe-Based Metal–Organic Frameworks

Metal−organic frameworks (MOFs), especially Fe-MOFs, have shown prospective application in eliminating organic dyes from wastewater due to their well-developed pores, water stability, easy preparation, and economy. Herein, we synthesized four types of Fe-MOFs (such as MIL-88A, MIL-88B, MIL-100, and MIL-101) using the hydrothermal method. The products were analyzed with several methods. By comparing the adsorption effect of those four types of Fe-MOFs on three kinds of dyes, it has been shown that MIL-100 owns the best adsorption efficiency on cationic organic dyes methylene blue (MB) and Rhodamine B (RhB) in 180 min, while all MOFs have slight removal capacity on methyl orange (MO). MIL-100, as an adsorbent, was studied under various research conditions, and the maximum removal efficiencies to MB, RhB, and MO were found to be up to 97.36%, 88.75%, and 13.00%, respectively. Furthermore, cationic dye MB's removal by MIL-100 was fitted with a pseudo-second-order model and Langmuir isotherm model (Q m = 411.041 mg/g) by adsorption kinetics and isotherms research, and MIL-100 could rapidly and selectively divide MB from a binary complex aqueous solution of MB and MO. The as-fabricated MIL-100 also exhibited excellent recyclability after four adsorption−desorption recycles and can be treated as a potential substance with high removal efficiency of cationic organic dye-containing industrial effluents.
