3D-Printing of Pure Metal–Organic Framework Monoliths

Lim, Gwendolyn J. H.; Wu, Yue; Shah, Bhuvan B.; Koh, J. Justin; Liu, Connie K.; Zhao, Dan; Cheetham, Anthony K.; Wang, John; Ding, Jun

Metal–organic frameworks (MOFs) are usually synthesized in powder form. For many practical applications, MOFs need to be shaped into monoliths that can be easily handled. However, conventional shaping methods, such as pelletization, often result in a decrease in functionality. Recently, MOF-containing monoliths have been made using direct ink writing (DIW;…

Unlocking Simultaneously the Temperature and Electrochemical Windows of Aqueous Phthalocyanine Electrolytes

Huang, Zhifeng; Zhang, Peng; Gao, Xinpei; Henkensmeier, Dirk; Passerini, Stefano; Chen, Ruiyong

The change from organic solvents to aqueous solvents for safe and robust battery electrolytes is desirable for electrochemical energy storage. Thermodynamically, water has an electrochemical stability window of 1.23 V, and pure water freezes at 0 °C. Such properties clearly restrict the high-voltage applications and temperature adaptability of aqueous electrolytes.…

Transforming an inert nanopolymer into broad-spectrum bactericidal by superstructure tuning

Scilletta, Natalia A.; Pezzoni, Magdalena; Desimone, Martín F.; Soler-Illia, Galo J.A.A.; Catalano, Paolo N.; Bellino, Martín G.

Poloxamer block copolymers (also known as Pluronic®) are particularly useful for drug delivery and self-assembly techniques. These nanopolymers are generally considered to be biologically inert and they were used to generate only bacteria repellent surfaces but keeps bacteria alive and as a latent threat. However, the inherent capabilities of these…

Li6C60 has been chosen as the most representative system to study the hydrogenation mechanism in alkali-cluster intercalated fullerides. We present here a muon spin relaxation (?SR) experiment that hints the chance to achieve a higher storage capacity on fullerene with respect to the values suggested in literature. Moreover, a linear…

Partial Transformation of Imogolite by Decylphosphonic Acid Yields an Interface Active Composite Material

Lange, Tobias; Charpentier, Thibault; Gobeaux, Frédéric; Charton, Sophie; Testard, Fabienne; Thill, Antoine

The phosphonic acid moiety is commonly used as an anchoring group for the surface modification of imogolite. However, the impact of the reaction on its structure has never been clearly analyzed before. We study the reaction of imogolite and decylphosphonic acid by combining infrared spectroscopy, X-ray scattering, scanning electron microscopy,…

Overcoming the Interfacial Lattice Mismatch: Geometry Control of Gold–Nickel Bimetallic Heteronanostructures

Li, Guangfang Grace; Blom, Douglas A.; Pandey, Shubham; Koch, Robert J.; Misture, Scott T.; Phillpot, Simon R.; Wang, Hui

Seed-mediated heteroepitaxial growth provides a versatile synthetic approach to a diverse set of geometrically distinct bimetallic heteronanostructures. In bimetallic nanocrystal systems, interfacial heteroepitaxial growth typically occurs between structurally similar metals with lattice mismatch below 5%, whereas controlled epitaxial growth of bimetallic nanocrystals comprising metals with…

Kinetically controlled, seed-mediated co-reduction provides a robust and versatile synthetic approach to multimetallic nanoparticles with precisely controlled geometries and compositions. Here, we demonstrate that single-crystalline cylindrical Au nanorods selectively transform into a series of structurally distinct Au@Au–Pd alloy core–shell bimetallic nanorods with exotic multifaceted geometries…

Residual Silver Remarkably Enhances Electrocatalytic Activity and Durability of Dealloyed Gold Nanosponge Particles

Li, Guangfang Grace; Lin, Ye; Wang, Hui

Percolation dealloying of multimetallic alloys entangles the selective dissolution of the less-noble elements with nanoscale restructuring of the more-noble components, resulting in the formation of spongelike, nanoporous architectures with a unique set of structural characteristics highly desirable for heterogeneous catalysis. Although the dealloyed nanoporous materials are compositionally…

Oschatz, M.; Deelen, T. W. van; Weber, J. L.; Lamme, W. S.; Wang, G.; Goderis, B.; Verkinderen, O.; Dugulan, A. I.; Jong, K. P. de

Lower C2–C4 olefins are important commodity chemicals usually produced by steam cracking of naphtha or fluid catalytic cracking of vacuum gas oil. The Fischer–Tropsch synthesis of lower olefins (FTO) with iron-based catalysts uses synthesis gas as an alternative feedstock. Nanostructured carbon materials are widely applied as supports for the iron…
