Fabricating Mechanically Robust Binder-Free Structured Zeolites by 3D Printing Coupled with Zeolite Soldering: A Superior Configuration for CO2 Capture.

ABSTRACT: 3D-printing technology is a promising approach for rapidly and precisely manufacturing zeolite adsorbents with desirable configurations. However, the trade-off among mechanical stability, adsorption capacity, and diffusion kinetics remains an elusive challenge for the practical application of 3D-printed zeolites. Herein, a facile "3D printing and zeolite soldering" strategy is developed to construct mechanically robust binder-free zeolite monoliths (ZM-BF) with hierarchical structures, which can act as a superior configuration for CO2 capture. Halloysite nanotubes are employed as printing ink additives, which serve as both reinforcing materials and precursor materials for integrating ZM-BF by ultrastrong interfacial "zeolite-bonds" subjected to hydrothermal treatment. ZM-BF exhibits outsta
