Adsorption technology utilizing zeolites as adsorbents is a highly efficient and cost-effective method for controlling the emission of volatile organic compounds (VOCs). Herein; two hierarchical diatomite/FAU-type zeolite composites were synthesized by a seeding-assisted secondary hydrothermal growth method and high-temperature hydrothermal dealumination; respectively. The adsorption properties of the composites for VOCs; such as toluene; ethyl acetate; n-heptane; methanol and acetone; were systematically evaluated. The pseudo-second-order model provided a perfect fit to adsorption kinetics; while the Langmuir model agreed the best with the adsorption isotherms. Furthermore; Dt/USY has remarkable recycling stability even after five regeneration cycles; resulting in outstanding VOCs adsorption efficacy. © 2024;
