Applications of carbon materials derived from metal-organic frameworks (MOFs)

20 февраля, 2019 - 18:10
Directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons, widely used as electrode materials, due to its flexibility and simplicity. These materials present certain drawbacks, though, such as low surface areas, disordered structures, and non-uniform sizes, which will greatly limit their applications. However, researchers found that carbon materials derived from metal-organic frameworks (MOFs) could overcome these limitations. A review summarizes the applications of MOF-derived carbon materials.
