Inside Back Cover: Puffing Up Energetic Metal–Organic Frameworks to Large Carbon Networks with Hierarchical Porosity and Atomically Dispersed Metal Sites (Angew. Chem. Int. Ed. 7/2019)

An energetic metal–organic framework (EMOF) with pre-imbedded transition-metal ions serves as a precursor for the fabrication of large carbon networks with hierarchical pores and atomically dispersed metal sites (ADMSs). In their Communication on page 1975 ff., Q. Xu, R. Zou, and co-workers describe the high-temperature carbonization of this material: the zinc-based triazole-rich nanoparticles puff up to form sub-millimeter-scale carbon networks, while the pre-imbedded transition-metal ions are transformed into active ADMSs.
