Hectogram-scale green synthesis of hierarchical 4A zeolite@CuO _x (OH)_(2-2x) (0 ≤ x < 1) nanosheet assemblies core-shell nanoarchitectures with Superb Congo red adsorption performance.

ABSTRACT: Delicate design of hierarchical nanoarchitectures has become a highly effective strategy to develop novel adsorbents with improved adsorption capacity. Herein, hectogram-scale green fabrication of hierarchical 4A zeolite@CuO _x (OH)_(2-2x) (0 ≤ x < 1) nanosheet assemblies core-shell nanoarchitectures (4A-Cu-T, T was the calcination temperature) with terrific Congo red (CR) dye adsorption performance was achieved through a simple, template-free and surfactant-free hydrothermal approach. A series of characterization techniques, including scanning electron microscopy, transmission electron microscopy, X-ray diffraction and photoelectron spectroscopy demonstrated that all resultant adsorbents featured a core-shell structure with 4A zeolite
