“…90,121 Zanco et al reported the first experimental validation between the packed bed and packed foam performance for carbon capture. 124 They found that packed foam had faster heat transfer and homogeneous distribution than conventional fixed beds. The cooling and heating in packed cell foams were significantly reduced but at the cost of the decreased capacity.…”

“…Zanco et al showed how heat transfer in a packed bed could be significantly improved by using open-cell foams with increased productivity of a CO2 capture TSA process of 80%. 99 Meanwhile, alternative heating methods are important to consider, such as microwave heating, Joule heating, and induction heating. 67,[100][101][102][103][104] These can also help to electrify the process and reduce the requirement for additional equipment to convert electricity into heat, like heat pumps.…”

Direct air capture using solid adsorbents is a proven technology critical to reducing our net greenhouse gas emissions to zero and beyond. Currently, academic research into the technology mainly focuses on the development of new adsorbents. However, there is a discord between the adsorbent design and process performance. Many materials scientists focus on maximising metrics such as the CO2 capacity of their adsorbent. Here, we combine detailed process modelling, machine learning, and extensive global sensitivity analysis, which entails varying all of the model parameters together, on a direct air capture process to show that the CO2 adsorption capacity is not one of the critical parameters for an amine-functionalised adsorbent operating in a temperature vacuum swing adsorption (TVSA) process, while it is important in a steam-assisted TVSA (S-TVSA) process. In fact, adsorption kinetics, density, and thermal conductivity are all critical attributes to obtaining a low energy penalty and reduced costs. The analysis also highlights the importance of heat transfer, directing process engineers to (alternative) adsorber designs that maximise this. By an in-depth evaluation of how process performance indicators are affected by materials properties and process operating parameters, this work provides guidance to both material scientists and process engineers towards the design of a "unicorn adsorbent" and intensified DAC processes. This will improve the performance of solid adsorbent direct air capture and help drive down the costs of this vital technology to avert the worst impacts of climate change.

“…The control of ceria morphological properties, such as particle size and distribution, crystallinity, surface area, and pore size, is a matter of great interest for its application to electrodes and electrolytes, ceramic monoliths, and catalytic formulations. , Indeed, it has been extensively shown that the morphology of CeO 2 heavily influences its performance in many catalytic reactions, − improves its oxygen storage capacity, − increases thermal stability, − promotes the metal–support interaction of supported metals, − has a high ionic conductivity as electrolyte in solid oxide fuel cells, and improves the mechanical and thermal stability of electrode layers. − In addition, recent advances in structured catalyst preparation have proposed 3D printing as a method to prepare cell-based monoliths composed entirely of the support oxide, − and it is well known that the size, shape, and distribution of starting powders is key to obtaining a printed manufact with solid mechanical resistance , as well as to improving flowability and processability in a scaled-up outlook …”

Cerium oxide powders are widely used and are of fundamental importance in catalytic pollution control and energy production due to the unique chemical properties of CeO 2 . Processing steps involved in catalyst preparation, such as hightemperature calcination or mechanical milling processes, can alter the morphological and chemical properties of ceria, heavily affecting its final properties. Here, we focus on the tuning of CeO 2 nanopowder properties by mild-and high-energy milling processes, as the mechanochemical synthesis is gaining increasing attention as a green synthesis method for catalyst production. The textural and redox properties were analyzed by an array of techniques to follow the aggregation and comminution mechanisms induced by mechanical stresses, which are more prominent under high-energy conditions but strongly depend on the starting properties of the ceria powders. Simultaneously, the evolution of surface defects and chemical properties was followed by Raman spectroscopy and H 2 reduction tests, ultimately revealing a trade-off effect between structural and redox properties induced by the mechanochemical action. The mild-energy process appears to induce the largest enhancement in surface properties while maintaining bulk properties of the starting materials, hence confirming its effectiveness for its exploitation in catalysis.
