3D-Printed Binary Monoliths

About

The technology is the development of binary, self-standing, monoliths produced by 3D-printing technique for dual functional processes. By seperately printing layered contactors of different supports, it is possible to formulate self-standing structures with dual-functionalities for advanced reaction processes. Presently, dual-layered metal-organic frameworks (MOFs) and MOF-zeolite have been monoliths formulated by the binary 3D-printing technique for CO2 adsorption and separation processes. The 3D-printed MOF-74(Ni)/HKUST-1(Cu) and HKUST-1(Cu)/zeolite 5A monoliths composed of 65/70 and 81/70 wt. % of adsorbent loading, respectively, bentonite clay as a binder, poly(vinyl alcohol) as a co-binder, methylcellulose as an organic plasticizer, and a solvent. The binary 3D printing technique will be used to produce zeolite/metal oxide and HKUST-1/graphene oxide monoliths. The zeolite/metal oxide monoliths will be used for the simultaneous capture and conversion of CO2 into methanol or other species. Overall, this technique allows for the simple, scalable, production of dual functional materials for simultaneous chemical processes.
