“…Common disposal methods include open-field incineration and storage, but these methods cause energy waste, greenhouse gas emissions, air pollution, and land occupation (Ng et al 2015 ). Contrary to all these problems, considering the high silica content of rice husk, various processes have been developed in which it is used as a raw material source in the production of zeolite, which is a value-added material, and studies have been carried out and are currently ongoing on the removal of unwanted materials with the resulting zeolite by the adsorption method (Chanda et al 2023 ; Flores et al 2021 ; Jin et al 2023 ; Lee et al 2023a , b ; Tran-Nguyen et al 2021 ).…”

“…As the need for energy increases, coal, natural gas, and oil reserves used as raw materials are depleted and the use of these resources causes global warming. Among alternative energy sources, solar energy technology is a promising technology with its environmentally friendly and renewable features (Lee et al 2023a , b ; Sharma et al 2021 ).…”

Increasing world population, urbanization, and industrialization have led to an increase in demand in production and consumption, resulting in an increase in industrial solid wastes and pollutant levels in water. These two main consequences have become global problems. The high Si and Al content of solid wastes suggests that they can be used as raw materials for the synthesis of zeolites. In this context, when the literature studies conducted to obtain synthetic zeolites are evaluated, it is seen that hydrothermal synthesis method is generally used. In order to improve the performance of the hydrothermal synthesis method in terms of energy cost, synthesis time, and even product quality, additional methods such as alkaline fusion, ultrasonic effect, and microwave support have been developed. The zeolites synthesized by different techniques exhibit superior properties such as high surface area and well-defined pore sizes, thermal stability, high cation exchange capacity, high regeneration ability, and catalytic activity. Due to these specific properties, zeolites are recognized as one of the most effective methods for the removal of pollutants. The toxic properties of heavy metals and dyes in water and their carcinogenic effects in long-term exposure pose a serious risk to living organisms. Therefore, they should be treated at specified levels before discharge to the environment. In this review study, processes including different methods developed for the production of zeolites from industrial solid wastes were evaluated. Studies using synthetic zeolites for the removal of high levels of health and environmental risks such as heavy metals and dyes are reviewed. In addition, EPMA, SEM, EDX, FTIR, BET, AFM, and 29Si and 27Al NMR techniques, which are characterization methods of synthetic zeolites, are presented and the cation exchange capacity, thermodynamics of adsorption, effect of temperature, and pH are investigated. It is expected that energy consumption can be reduced by large-scale applications of alternative techniques developed for zeolite synthesis and their introduction into the industry. It is envisaged that zeolites synthesized by utilizing wastes will be effective in obtaining a green technology. The use of synthesized zeolites in a wide variety of applications, especially in environmental problems, holds great promise. Graphical Abstract

“…Notably, tubular clay nanomaterials, specifically Halloysite, have been utilized as triple-functional materials: the source of alumina and silica, and hard template [176][177][178][179][180]. It should be noted that bioresources, such as water reeds (Phragmites) [181] and rice husk ash [182][183][184][185][186][187], mineral sources including rectorite [188] and diatomite [189,190], and industrial wastes like coal fly ash [191,192], have a minor scale, but employed as sources of silica and alumina in the synthesis above. This advancement represents a notable step forward in green chemistry for zeolite production.…”

Upgrading the properties of diesel fractions is considered one of the crucial processes in the petrochemical industry; and for this purpose in laboratory-scale researching it is studied on the base of the hydroisomerization of n-hexadecane as a main model reaction. Recently, zeolite-based bifunctional catalysts have proven their efficiency due to their remarkable acidity, shape-selectivity and relative resistance to deactivation. In this review, different topological-type zeolite-based catalysts, the mechanism of their catalytic effect in n-C16 isomerization, and the principles of shape-selectivity are reviewed. A comparison of their structural-operational characteristics is made. The impact of some feedstock impurities on the catalyst’s performance and deactivation due to carbonaceous deposits as well as various modern eco-friendly cost-effective synthesis techniques are also discussed.
