Zeolites synthesized from industrial and agricultural solid waste and their applications: A review

With the rapid development of industrialization and urbanization, coal-based solid waste, agricultural and forestry wastes, urban solid waste, and other by-products are inevitably produced. The management and utilization of these solid wastes have become a considerable challenge. Given that the main components of these industrial and agricultural solid wastes are similar to zeolites, they are ideal silicon and aluminum sources for zeolite synthesis, which has attracted extensive attention from researchers. Therefore, this review first summarizes the basic properties of industrial and agricultural solid wastes. Then the typical synthetic strategies for synthesizing zeolites from solid wastes and the mechanism of zeolite formation are elaborated. In addition, the recent applications of various types of zeolite materials in wastewater, waste gas, agriculture, etc., are also reviewed more comprehensively. Finally, the perspectives for future research on solid waste zeolite synthesis are presented to provide some references for researchers in this field.
