Synthesis and Applications of Magnetic Zeolites: A Comprehensive Review
摘要
Magnetic zeolites are gaining a lot of attention for their potential in adsorption and catalytic applications. This review summarizes the structural characteristics and synthesis methods of three types of magnetic zeolites: internal magnetic zeolites, external magnetic zeolites, and complex magnetic zeolites. The application properties of various magnetic zeolites are discussed in detail, including their use in heavy metal adsorption, ammonia nitrogen removal from wastewater, radioactive waste adsorption, and oil contamination removal. Numerous studies have demonstrated that magnetic zeolites possess high magnetization (e.g., > 4 emu·g−1), enabling rapid and efficient magnetic separation of zeolite adsorbents. Magnetic zeolites also exhibit excellent adsorption and catalytic performance, maintaining their effectiveness even after multiple cycles (e.g., more than five cycles).
