“…[ 36 ] Albouyeh et al indicated the pH PZC of MOF‐74 is 2.8. [ 37 ] However, AlO(OH) with high pH PZC with respect to MOF‐74 causes a further increment of pH PZC value in AlO(OH)/MOF‐74 nanocomposite. A compound with a negative charge indicates a higher ability to absorb positively charged compounds and contrariwise.…”

In the present work, boehmite metal‐organic framework nanocomposite, AlO(OH)/MOF‐74(Zn), was synthesized by a simple, fast, and low‐cost process. The post‐synthetic method was used for preparing new hybrid material. The photocatalytic efficiency of AlO(OH)/MOF‐74(Zn) was investigated by photocatalytic degradation of Congo Red anionic dye. The nanocomposite was characterized by various techniques. The electron microscopy images showed that the spherical MOF‐74 with about 30 nm was located over boehmite. The optical properties indicated the boehmite/MOF‐74 can be used as a visible‐light‐driven photocatalyst. Optimization of significant variables such as adsorbent dosage and initial Congo Red concentration and photodegradation time affecting removal was investigated and the optimized values were found to be 1 g/L, 10 mg/L, and 60 min, respectively. The AlO(OH)/MOF‐74(Zn) photocatalyst exhibited the highest catalytic performance for photodegradation of dye contaminants. Results indicated about 94% of tested dye were removed by a new hybrid photocatalyst under visible light irradiation. The results confirmed that due to some considerable features of AlO(OH)/MOF‐74(Zn) such as high surface area and chemical and thermal resistance, the introduced photocatalyst acts as a high‐performance photocatalyst for degradation of Congo Red dye in aqueous solutions.

“…As can be seen from Table 3, a higher degradation time and a greater amount of photocatalyst are required in the presence of AlO(OH) and MOFs. [37,[44][45][46][47][48][49] But nanocomposites of MOFs with zeolites [37] or AlO(OH) decrease the time and amount of photocatalyst.…”

Zeolite@MOF composite is a bifunctional composite formed from thermal and structural stable inorganic zeolite and high tunable surface area and structural flexible MOF. The parent material “MOF” has a higher surface area and structural elasticity than zeolite. Nevertheless, MOF is more structurally and mechanically unstable than zeolite. Thus, compositing of structural stable zeolite with tunable porous MOF has enhanced the applications of Zeolite@MOFcomposite over its parent materials. The Zeolite@MOF composite was synthesized through the hydrothermal method, the solvothermal method, the refluxing method, and the microwave-assisted method. The synthesized Zeolite@MOF composite also further modified via postsynthesis or presynthesis modification method to bring them extra functionality. Recently, researchers have synthesized Zeolite@MOF composite using hydrothermal method for zeolite crystallization and then solvothermal growth of MOF over presynthesized zeolite surface to reduce competitions between zeolite and MOF precursors through nucleation and crystal formation. The structure of Zeolite@MOF composite, such as morphology, microstructure, functional group, particle size, elemental composition, and weight loss was also analysed using SEM, TEM, FTIR, X-RD, EDX, and TAG, respectively. After exploring the characterization techniques of Zeolite@MOF composite, a performance application of Zeolite@MOF was also reviewed. Zeolite@MOF is used for the degradation of organic dyes (methyl blue and methyl orange) from wastewater; zeolite@MOF is also used as a catalyst in the synthesis of organic compounds. Zeolite@MOF composites showed higher catalytic activity, high selectivity, and high product yield than the corresponding zeolite and MOF parent materials. Hence, the compositing of zeolite and MOF is promising to overcome the individual limitations of zeolite and MOF. Zeolite@MOF composite has a synergic performance advantage over its parent materials.

“…For example, zeolites such as chabazite, zeolite Y, mordenite, faujasite and LTA have already been studied as catalyst carriers for the degradation of organic dyes [31][32][33]. In addition to the zeolite ZSM-12, which has been used in the photodegradation of MB with relatively low removal results [34], the synthesis of composite materials such as Zn-ZSM-5 [35], TiO 2 /Ni-ZSM-5 [36], g-C 3 N 4 -H-ZSM-5 [37] and clinoptilolite [38] improves the adsorption of MB to the zeolite surface, obtaining high photodegradation efficiencies.…”

A chabazite-type zeolite was prepared by the hydrothermal method. Before ion exchange, the chabazite was activated with ammonium chloride (NH4Cl). The ion exchange process was carried out at a controlled temperature and constant stirring to obtain ion-exchanged chabazites of Ti4+ chabazite (TiCHA), Zn2+ chabazite (ZnCHA), Cu2+ chabazite (CuCHA), Ag+ chabazite (AgCHA) and Au3+ chabazite (AuCHA). Modified chabazite samples were characterized by X-ray diffraction (XRD), scanning electron microscope equipped with energy-dispersive spectroscopy (SEM-EDS), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), N2 adsorption methods and UV–visible diffuse reflectance spectroscopy (DRS). XRD results revealed that the chabazite structure did not undergo any modification during the exchange treatments. The photocatalytic activity of chabazite samples was evaluated by the degradation of methylene blue (MB) in the presence of H2O2 under ultraviolet (UV) light illumination. The photodegradation results showed a higher degradation efficiency of modified chabazites, compared to the synthesized chabazite. CuCHA showed an efficiency of 98.92% in MB degradation, with a constant of k = 0.0266 min−1 following a first-order kinetic mechanism. Then, it was demonstrated that the modified chabazites could be used for the photodegradation of dyes.
