Rising atmospheric CO2 concentration has exceeded nature’s carbon recycling capacity and caused severe environmental hazards. To capture CO2 from point sources and from atmospheric air, various solid CO2 adsorbents, including zeolites, metal organic frameworks (MOFs) and immobilized amines, have been developed. While this has been a promising development, the discrete nature of the solid adsorbents limits their applications without the use of a substrate. To reduce energy cost of direct air capture, it is important to develop a structured adsorbent with both high adsorbent efficiency and low gas pressure drop. In this work, we proposed a 3D-printing technique to manufacture a structured CO2 adsorbent, in which a solid adsorbent is supported by a highly permeable polymer with intrinsic microporosity (PIM-1). This method of adsorbent development allows for customizable substrate patterning and sizing, thereby allowing for the transport properties through the adsorbent to be tuned. Compared with existing 3D-printing techniques for structured adsorbent manufacture, our technique features mild activation conditions and low internal mass transfer resistance. The solid adsorbents selected for the study include Mg-MOF-74, HKUST-1, and Zeolite 13X. Rheological studies were performed to determine the optimal loading compositions for the polymer-adsorbent inks and these inks were successfully printed.
