Our review paper on 3D printing in chemical engineering and catalytic technology was accepted in Chemical Society Reviews.
In the field of catalytic technology and chemical engineering the impact of 3D printing, is steadily increasing thanks to a rapidly decreasing equipment threshold. Although still in an early stage, the rapid and seamless transition between digital data and physical objects enabled by these fabrication tools will benefit both research and manufacture of reactors and structured catalysts. 3D printing closes the gap between theory and experiment, by enabling accurate fabrication of geometries optimized through computational fluid dynamics and the experimental evaluation of their properties. Our review highlights the research using 3D printing and computational modeling as digital tools for the design and fabrication of reactors and structured catalysts. The goal of this contribution is to stimulate interactions at the crossroads of chemistry and materials science on the one hand and digital fabrication and computational modeling on the other.
Timothée’s ChemSusChem paper tries to demonstrate how the superior adsorptive properties of porous and crystalline metal-organic framework (MOFs) offer novel and sustainable alternatives for the recovery of biobased fermentative products. This paper resulted from a collaboration with the De Vos group, Stock group (CAU, DE) and Bein group (LMU, DE).
The study focuses on biomass-derived lactic acid, an important platform chemical towards the sustainable production of numerous materials such as the biodegradable poly(lactic acid). The current fermentation process is however limited by the difficulty to recover the lactic acid product from the fermentation broth. Further, the recovery process generates stoichiometric amounts of gypsum which needs to be disposed, thereby implying costs as well as sustainability issues. Our study reveals the high affinity of lactic for open metal sites in Zr-based MOFs and how their use as adsorbent could shortcut most of the multi-step separation process in use, and avoid gypsum generation.
Materials processing, and thin-film deposition in particular, is decisive in the implementation of functional materials in industry and real-world applications. Vapor processing of materials plays a central role in manufacturing, especially in electronics. Metal–organic frameworks (MOFs) are a class of nanoporous crystalline materials on the brink of breakthrough in many application areas. Vapor deposition of MOF thin films will facilitate their implementation in micro- and nanofabrication research and industries. In addition, vapor–solid modification can be used for postsynthetic tailoring of MOF properties. In this context, we review the recent progress in vapor processing of MOFs, summarize the underpinning chemistry and principles, and highlight promising directions for future research.
In this Chemistry - A European Journal paper we try to highlight the underlying concepts of vapor phase growth of MOFs and which exciting perspectives this MOF-CVD approach opens.
