3D-printed ZSM-5 monoliths with metal dopants for methanol conversion in the presence and absence of carbon dioxide

3D Printed Palladium Catalyst for Suzuki‐Miyaura Cross‐coupling Reactions

“…The technology of additive manufacturing, broadly known as three‐dimensional (3d) printing, has been evolving extensively in the last decades, and recently catalytically active 3d printed objects started to emerge . Indeed, 3d printing provides potential for creating objects not only with desired catalytic properties, but at the same time with required shapes, e. g. for batch or flow reactors with heterogeneous solid catalysts.…”

“…Indeed, 3d printing provides potential for creating objects not only with desired catalytic properties, but at the same time with required shapes, e. g. for batch or flow reactors with heterogeneous solid catalysts. A number of reports emerged recently on new catalysts for various reactions, produced by 3d printing with and without chemical post‐processing of the printed objects. Among these reports, the majority utilizes fused deposition modelling (FDM) or robocasting, selective laser melting (SLM), and in some cases stereolithography (SL) methods.…”

3D Printing in Heterogeneous Catalysis—The State of the Art

“…Another research team used a laboratory-scale 3D printer to extrude zeolite catalysts based on HZSM-5, HY, and ZSM-5 doped with various metal oxides [ 59 , 60 , 61 , 62 , 63 , 64 ]. An MTO process was performed to test the monoliths made of HZSM-5, including monoliths which also contained amorphous silica integrated with the structure and monoliths surface-coated with SAPO-34 zeolite.…”

“…With N 2 replaced with CO 2 and with the reaction maintained at 400 °C, the selectivity to ethylene decreased, while the selectivity to propylene was almost constant. The Y and Zn-doped monoliths proved a higher selectivity of light olefins and BTX compounds (benzene, toluene, and xylene) in the absence and presence of CO 2 , respectively [ 61 ]. The catalytic performance of the monolithic structures 3D-printed with HZSM-5 and HY zeolites, including a version with the surface modified by SAPO-34, was also tested by n-hexane cracking.…”

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

“…However, subjected to the inflexible configuration, complicated manufacturing process, and poor mechanical integrity, this strategy still faces many obstacles for their largescale implementation. [28][29][30][31] However, due to the difficulty of integrating individual zeolite crystals with robust interfacial binding, the practical use of 3D-printed structured zeolites is severely restricted by their insufficient mechanical strength. [20][21][22][23] Various porous materials including porous ceramics, [24] porous polymers, [25] metalorganic frameworks, [26] and covalent organic frameworks [27] with complex self-supporting architectures have been successfully fabricated by 3D printing, particularly, 3D printing has proven to be an attractive strategy to tailor monolithic zeolite adsorbents and catalysts with hierarchical structures that are favorable for diffusions.…”
