Advances in the Application of MOFs-Derived Heterostructures in Electrocatalysis
The electrocatalyst is affected by numerous factors, such as structure, composition and surface interface proper-ties. It is of great significance to construct an efficient and stable transition metal based nano-catalyst to achieve excellent catalytic performance for efficient energy conversion and storage. The construction of heterogeneous materials has better cat-alytic performance compared with single-structure materials because of its ability to play the synergistic effect of the inter-face between various components. Interface engineering by constructing heterogeneous structures has been proved to be an effective method to develop high efficiency electrocatalysts. In view of this, the advantages, disadvantages and structural characteristics of heterogeneous structures derived from MOFs are summarized in this paper. The design and construction of heterogeneous structures derived from MOFs are briefly classified. In addition, MOFs-derived heterogeneous transition met-al catalysts are used as oxygen and hydrogen electrode materials. Finally, the further research and application of heteroge-neous transition metal catalysts for electrochemical energy conversion and storage are summarized.
