“…To overcome these issues, various mesoporous agents have been used to form the ZSM‐5 structure, including monosaccharides and disaccharides (such as glucose and sucrose), which are low‐cost mesoporous agents that can be adapted into a green approach to introduce secondary mesopores into the zeolite structure 68,78,110 . Some studies have utilized alcohol, 111,112 mesoporous carbon, 113,114 inorganic ions, 115 and anionic surfactants 116 to synthesize ZSM‐5 zeolite, while other investigations have claimed a template‐free synthesis of ZSM‐5 69,87,117‐119 . In particular, a recent study employed sugarcane residues, an inexpensive biomass‐based source, as crystal growth modifiers to considerably reduce the quantity of organic template tetrapropylammonium hydroxide (TPA‐OH) required to synthesize ZSM‐5 zeolite 120 .…”

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).
