In Situ Transformation of MOFs into Layered Double Hydroxide Embedded Metal Sulfides for Improved Electrocatalytic and Supercapacitive Performance
National University of Singapore · Nanyang Technological University
Abstract
Direct adoption of metal‐organic frameworks (MOFs) as electrode materials shows impoverished electrochemical performance owing to low electrical conductivity and poor chemical stability. In this study, we demonstrate self‐templated pseudomorphic transformation of MOF into surface chemistry rich hollow framework that delivers highly reactive, durable, and universal electrochemically active energy conversion and storage functionalities. In situ pseudomorphic transformation of MOF‐derived hollow rhombic dodecahedron template and sulfurization of nickel cobalt layered double hydroxides (NiCo‐LDHs) lead to the construction of interlayered metal sulfides (NiCo‐LDH/Co 9 S 8 ) system. The embedment of metal sulfide…
