Review on the Progress of Core-Shell Structured Zeolite Molecular Sieve Materials

The unique zeolite-based core-shell structures showed excellent performance in the coal chemical, petrochemical and fine chemical industries. The synthesis and applications of core-shell structured zeolite composite materials were systematically reviewed. Three core-shell structures for the zeolite composite materials were involved, including zeolite-based crystal as cores, zeolite-based materials as the shells and zeolites@zeolites core-shell structures. The hollow zeolite crystals and the magnetic@zeolites core-shell composites were also mentioned as two kinds of distinguished core-shell structured zeolite composites. The development and application prospects of zeolite-based core-shell structure composite materials were also discussed.
