This work tries to synthesize ZSM-5 zeolite using fly ash (FA) by hydrothermal method and study the adsorption effect of the zeolite on phenol, quinoline and indole in aqueous solution. The zeolites were characterized with x-ray diffraction (XRD), scanning electron microscopy (SEM), x-ray fluorescence (XRF), fourier transformation infrared (FTIR) and N 2 adsorption-desorption isotherm. The characterization results showed that HZSM-5 zeolite was successfully synthesized. The higher mass ratio of sodium carbonate to fly ash during melting is beneficial to improve the purity of ZSM-5 zeolite and its removal rate of organic matters. These results have been confirmed by XRD and principal component analysis (PCA). The adsorption process of phenol, quinoline and indole in aqueous can be well described with the double exponential kinetic model. The adsorption capacity of ZSM-5 zeolite for phenol, quinoline and indoles can be up to 24.41 mg g −1 , 35.99 mg l −1 and 34.05 mg g −1 respectively, and the removal rates can reach up to 82.80%, 84.86% and 83.20% respectively. The optimal pH value for adsorption ranges from 5 to 7.

“…82 From 2018 to present, scientists have paid close attention to the synthesis and application of ZSM-5 from fly ash, as evidenced by the growing number of publications. Some research has focused on the optimization of crystal formation 81 or the external surface phenomena in the dealumination and desilication of ZSM-5, 142 while others concentrated on the catalytic 83,125,143,144 or adsorptive performance. 80,90,126,145,146 To be more specific, ZSM-5 has been successfully used to eliminate volatile organic compounds (VOCs) or hazardous substances in aqueous solutions via adsorption.…”

“…69,[76][77][78][79] Although several studies have reported using clays as Si/Al precursors, there has been little progress in directly producing ZSM-5 zeolite from abundant natural resources, such as kaolinite. Furthermore, fly ash [80][81][82][83] and biomass plant ash (rice husk, silica fume, water reed) [84][85][86][87][88][89][90] containing high concentrations of Si or Al have been effective in the production of ZSM-5 zeolite. Other natural aluminosilicate minerals, such as silicon-rich diatomite, 91,92 aluminum-rich rectorite minerals, 85,[91][92][93] illite clay, 94,95 natural zeolite, 79,96 palygorskite, 97 and perlite, 98 have also been reported as novel, cost-effective, and eco-friendly precursors for the synthesis of ZSM-5 zeolite.…”

As a well‐known porous inorganic material formed of aluminosilicate structures, Zeolit Socony Mobil Number 5 (ZSM‐5) zeolite has been widely used for various applications, especially oil‐chemical conversion processes and environmental pollution treatment. This study provides an overview of the natural sources as well as the role and categorization of structural compounds used for the synthesis of ZSM‐5. Overall, clay, natural minerals, or leftovers from agricultural and industrial activities (all of which offer several advantages, such as low cost, availability, and environmental friendliness) have been used to manufacture ZSM‐5. Moreover, green structural directing agents (known as soft templates) have been increasingly employed to replace pure chemicals in the production of ZSM‐5, aiming to decrease unexpected effects on the environment. This research orientates the production of ZSM‐5 zeolite on a low‐cost and environmentally friendly industrial scale. © 2023 Society of Chemical Industry (SCI).

Hierarchical Cs–Pollucite Nanozeolite Modified with Novel Organosilane as an Excellent Solid Base Catalyst for Claisen–Schmidt Condensation of Benzaldehyde and Acetophenone

Cs–pollucite can be a potential solid base catalyst due to the presence of (Si-O-Al)−Cs+ basic sites. However, it severely suffers from molecular diffusion and pore accessibility problems due to its small micropore opening. Herein, we report the use of new organosilane, viz. dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride (TPOAC), as a promising pore-expanding agent to develop the hierarchical structure in nanosized Cs–pollucite. In respect to this, four different amounts of TPOAC were added during the synthesis of hierarchical Cs–pollucite (CP-x, x = 0, 0.3, 1.0, or 2.0, where x is the molar ratio of TPOAC) in order to investigate the effects of TPOAC in the crystallization process of Cs–pollucite. The results show that an addition of TPOAC altered the physico-chemical and morphological properties of hierarchical Cs–pollucite, such as the crystallinity, crystallite size, pore size distribution, surface areas, pore volume, and surface basicity. The prepared solids were also tested in Claisen–Schmidt condensation of benzaldehyde and acetophenone, where 82.2% of the conversion and 100% selectivity to chalcone were achieved by the CP-2.0 catalyst using non-microwave instant heating (200 °C, 100 min). The hierarchical CP-2.0 nanocatalyst also showed better catalytic performance than other homogenous and heterogeneous catalysts and displayed a high catalyst reusability with no significant deterioration in the catalytic performance even after five consecutive reaction runs.
