Inside Back Cover: Silica‐Protection‐Assisted Encapsulation of Cu 2 O Nanocubes into a Metal–Organic Framework (ZIF‐8) To Provide a Composite Catalyst (Angew. Chem. Int. Ed. 23/2018)

Abstract

Encapsulating metastable nanoparticles with high catalytic activity into metal–organic frameworks (MOFs) is still a great challenge. In their Communication on page 6834 ff., B. Li, J.-G. Ma, and P. Cheng develop a template-protection-sacrifice method to encapsulate metastable Cu2O nanoparticles into MOFs. SiO2 serves as a sacrificial template for forming the yolk–shell structure, as a protective shell for Cu2O nanocubes, and as a place holder in the porous composite material.
