Solvent‐Free Synthesis of Zeolitic Imidazolate Frameworks and the Catalytic Properties of Their Carbon Materials
Abstract
Zeolitic imidazolate frameworks (ZIFs) are traditionally synthesized solvothermally by using cost‐ and waste‐incurring organic solvents. Here, a direct synthesis method is reported for ZIF‐8, ZIF‐67, and their heterometallic versions from solid precursors only. This solvent‐free crystallization method not only completely avoids organic solvents, but also provides an effective path for the synthesis of homogeneous mixed‐metal ZIFs. Furthermore, under templating by NaCl/ZnCl2 eutectic salt, carbonization of the ZIF materials gives rise to a series of N‐containing high‐surface‐area carbon materials with impressive catalytic properties for the oxygen reduction reaction.
