Abstract
The development of zeolitic adsorbents is an essential subject of interest in the realm of
green chemistry, especially in the aspect of gas adsorption. The intrinsic molecular sieving
capacity of zeolites allows them to be widely adopted as effective gas adsorbents. As a
layer-by-layer deposition technology, three-dimensional (3D) printing can achieve more
complex zeolitic gas adsorbent structures than conventional manufacturing methods
by offering flexible freeform construction and controllable 3D structural design. This
review article focuses on the recent development of 3D-printed zeolitic gas adsorbents,
which integrate advanced zeolitic structures and emerging additive manufacturing
technologies for gas absorption. A description of zeolites and their conventional
fabrication methods is given for a basic understanding of zeolitic gas adsorbents. 3D
printing technologies are also introduced and discussed for the fabrication of zeolitic
adsorbents such as monoliths. Next, the recent progress in the fabrication of zeolitic gas
adsorbents using 3D printing is illustrated and summarized, which boosts the application
of 3D-printed zeolite absorbents in different fields of gas adsorption. Conclusions are
