Special Issue Information

Dear Colleagues,

The overall aim of this Special Issue is to promote novel materials for gas-to-liquid or biomass-to-liquid processes, encompassing the need to move towards an energy economy with greatly reduced net carbon emissions. In this context, sustainable technological approaches require the development of efficient solid catalysts or their optimization in order to deliver the constant and reliable management of energy for the production of large-volume chemicals, biofuels or building materials; this is performed so that these materials are able to quickly reach the market after follow-up, scale-up and validation activities. The Special Issue encourages original contributions and review articles on the most current and challenging areas of interest regarding energy, focusing on the conversion of fossil and renewable resources mediated by innovative catalytic materials, and in view of the ambitious decarbonization targets that are to be implemented worldwide in the coming decades.

In this work, a 3D printing methodology based on the robocasting of catalytic ink pastes was applied to obtain structured matrix-like cylinders as innovative materials for an effective utilization of carbon dioxide. The influence of three different binders (i.e., PEI, HPMC and MC) on the physio-chemical, mechanical and catalytic properties of multi-channel monoliths was studied against a reference binder-free powdered system in order to envisage the effectiveness of the printing procedure in realizing hybrid advanced materials at a higher control and reproducibility than from traditional preparation techniques. In terms of textural and structural properties, the micro-extruded 3D cylinders only evidenced a slight difference in terms of relative crystallinity, with minor effects on the surface area exposure in relation to the specific binder used during the direct ink writing process. More importantly, the typology of binder significantly affected the rheological properties of the catalytic ink, with the need of a controlled viscosity to ensure a suitable thixotropic behaviour of the extrudable pastes, finally determining an optimal mechanical resistance of the final 3D monolith. The experimental validation of the hybrid multi-channel cylinders under conditions of CO2 hydrogenation demonstrated the great potential of additive manufacturing in the realization of catalyst architectures characterized by unique features and fidelity scarcely reproducible via conventional synthetic techniques.
