From Meso to Macro: Controlling Hierarchical Porosity in Supraparticle Powders (Small 27/2023)

Abstract

Supraparticle Powders Controlling the structure and porosity in hierarchical materials is a key design feature that can enable their successful application in fields of chromatography, catalysis and adsorption. In article number 2300241, Benjamin Apeleo Zubiri, Alexandra Inayat, Nicolas Vogel, and co‐workers provide a versatile toolbox for designing hierarchical porous materials by tailoring the porosity in spray‐dried supraparticles from the meso‐ (3 nm) to the macroscale (≈10 µm).

Emergent Properties from Three-Dimensional Assemblies of (Nano)particles in Confined Spaces

“…However, the generation of high surface area superstructures, such as porous superparticles, enables important advantages such as sequestration, storage, and directed release of cargo, as well as increasing the reactivity of the superparticle for chemical reactions taking place on its surface . Over the past few years, a number of strategies have emerged to generate porous, high-surface area superparticles. − …”
