Abstract
AbstractNovel composites containing zeolitic imidazolate framework‐8 (ZIF‐8) nanocrystals and natural plant fibers (Juncus effusus (JE) fibers) are successfully synthesized. ZIF‐8 nanocrystals are coated onto hydrophilic JE fibers (H‐JE fibers) via biomimetic mineralization after only several seconds at room temperature (25 °C). The ZIF‐8/H‐JE fiber composite (stirring) and ZIF‐8‐BSA/H‐JE fiber composite (biomimetic mineralization) composite materials have excellent formaldehyde (HCHO) removal properties. ZIF‐8‐BSA/H‐JE fiber composites, in particular, are highly efficient HCHO adsorbents. Up to 99.79% HCHO removal at a high concentration (100 mg/m3) can be achieved within 90 min, and 100% removal can be achieved at a low concentration (10 mg/m3) within 17 min. This study provides an effective strategy for developing natural‐plant‐fiber‐based composite materials for environmental protection.
