Direct transformation of ZIF-8 into hollow porous carbons and hollow carbon composites

Hollow porous carbons (HPCs) are a class of porous materials with advantages of high surface to volume ratio, large interior cavities, low density, and short diffusion length, which are promising in various applications. Direct carbonization of carbon precursors is the simplest and the most cost-effective method to prepare porous carbons, however, it often leads to non-hollow structures. Herein, we demonstrate the preparation of HPCs through a …
