Large amounts of carbon monoxide are produced by industrial processes such as biomass gasification and steel manufacturing. The CO present in vent streams is often burnt, this produces a large amount of CO₂, e.g., oxidation of CO from metallurgic flue gasses is solely responsible for 2.7% of manmade CO₂ emissions. The...

Confined Water Cluster Formation in Water Harvesting by Metal–Organic Frameworks: CAU-10-H versus CAU-10-CH₃

van der Veen, M.A. (author), Canossa, S. (author), Wahiduzzaman, Mohammad (author), Nenert, Gwilherm (author), Frohlich, Dominik (author), Rega, D. (author), Reinsch, Helge (author), Shupletsov, Leonid (author), Markey, Karen (author)

Several metal–organic frameworks (MOFs) excel in harvesting water from the air or as heat pumps as they show a steep increase in water uptake at 10–30 % relative humidity (RH%). A precise understanding of which structural characteristics govern such behavior is lacking. Herein, CAU-10-H and CAU-10-CH₃ are studied with -H, -CH<sub>3...

Promoting Photocatalytic Activity of NH₂-MIL-125(Ti) for H₂ Evolution Reaction through Creation of Ti^III- and Co^I-Based Proton Reduction Sites

Kavun, Vitalii (author), Uslamin, E. (author), van der Linden, B. (author), Canossa, Stefano (author), Goryachev, A. (author), Bos, Emma E. (author), Garcia Santaclara, J. (author), Smolentsev, Grigory (author), Repo, Eveliina (author), van der Veen, M.A. (author)

Titanium-based metal-organic framework, NH2-MIL-125(Ti), has been widely investigated for photocatalytic applications but has low activity in the hydrogen evolution reaction (HER). In this work, we show a one-step low-cost postmodification of NH2-MIL-125(Ti) via impregnation of Co(NO3)2. The resulting Co@NH2-MIL-125(Ti) with embedded single...

Competitive and Cooperative CO₂-H₂O Adsorption through Humidity Control in a Polyimide Covalent Organic Framework

Veldhuizen, H.V. (author), Butt, Saira Alam (author), Van Leuken, Annemiek (author), van der Linden, B. (author), Rook, W. (author), van der Zwaag, S. (author), van der Veen, M.A. (author)

In order to capture and separate CO2 from the air or flue gas streams through nanoporous adsorbents, the influence of the humidity in these streams has to be taken into account as it hampers the capture process in two main ways: (1) water preferentially binds to CO2 adsorption sites and lowers the overall capacity, and (2) water causes...

Impact of flow-induced disturbances during synthesis on the photophysical properties of naphthalene diimide covalent organic frameworks

Veldhuizen, H.V. (author), van der Zwaag, S. (author), van der Veen, M.A. (author)

Flow-induced disturbances were applied during the synthesis of a naphthalene diimide covalent organic framework (NDI-COF), which resulted in different COF polymer networks. We discovered that a high intensity of stirring resulted in more aggregated structures on both the micro- and nano-length scale. Subsequently, these structures absorbed...

Structure-Property Relationship of Piezoelectric Properties in Zeolitic Imidazolate Frameworks: A Computational Study

Mula, S. (author), Donà, Lorenzo (author), Civalleri, Bartolomeo (author), van der Veen, M.A. (author)

Metal-organic frameworks (MOFs) are a class of nanoporous crystalline materials with very high structural tunability. They possess a very low dielectric permittivity ϵr due to their porosity and hence are favorable for piezoelectric energy harvesting. Even though they have huge potential as piezoelectric materials, a detailed analysis and...

Molecular-level understanding of highly selective heavy rare earth element uptake by organophosphorus modified MIL-101(Cr)

Keshavarz, Fatemeh (author), Kavun, V. (author), van der Veen, M.A. (author), Repo, Eveliina (author), Barbiellini, Bernardo (author)

Selective separation of rare earth elements (REEs) from solutions of mixed heavy and light metals by solid adsorbents is an important challenge in the fields of water treatment and metal recovery. The main challenge is water instability of many adsorbents, specifically metal–organic frameworks (MOFs), and their low selectivity. Grafting...

Pillared cobalt metal-organic frameworks act as chromatic polarizers

Gonzalez Nelson, A.M. (author), Joglekar, C.S. (author), van der Veen, M.A. (author)

The ease with which molecular building blocks can be ordered in metal–organic frameworks is an invaluable asset for many potential applications. In this work, we exploit this inherent order to produce chromatic polarizers based on visible-light linear dichroism via cobalt paddlewheel chromophores.

Emergence of Coupled Rotor Dynamics in Metal-Organic Frameworks via Tuned Steric Interactions

The organic components in metal-organic frameworks (MOFs) are unique: they are embedded in a crystalline lattice, yet, as they are separated from each other by tunable free space, a large variety of dynamic behavior can emerge. These rotational dynamics of the organic linkers are especially important due to their influence over properties...

Rotational dynamics of linkers in metal–organic frameworks

Gonzalez Nelson, A.M. (author), Coudert, François Xavier (author), van der Veen, M.A. (author)

Among the numerous fascinating properties of metal–organic frameworks (MOFs), their rotational dynamics is perhaps one of the most intriguing, with clear consequences for adsorption and separation of molecules, as well as for optical and mechanical properties. A closer look at the rotational mobility in MOF linkers reveals that it is not only...

Emergence of Nonlinear Optical Activity by Incorporation of a Linker Carrying the p-Nitroaniline Motif in MIL-53 Frameworks

p-Nitroaniline presents the typical motif of a second-order nonlinear optically (NLO) active molecule. However, because of its crystallization in an antiparallel and hence centrosymmetric structure, the NLO activity is lost. In this contribution, the p-nitroaniline motif was built successfully into the MIL-53 metal-organic framework. More...
