MOF-derived metal sulfides for electrochemical energy applications

As a new crystalline porous organic-inorganic hybrid materials, metal organic frameworks (MOFs) have been proved to be the ideal precursors for the preparation of metal sulfides, with higher catalytic potential and excellent catalytic activity in electrocatalysis as well as enhanced reversible capacity, superior rate, and cycle performance in electric energy storage. In this review, the recent progress (synthesis methods, compositions, structures, and reaction mechanisms) of MOF-derived metal sulfides for batteries (lithium-ion batteries, lithium-sulfur batteries, sodium-ion batteries, potassium ion batteries and so on), supercapacitors, and electrocatalysis have been summarized. At last, the challenges and opportunities faced by the future development of this field are put forward, hoping to provide some enlightenment for the synthesis of MOF-derived metal sulfides, so as to create more efficient and lasting electrochemical energy storage and conversion systems.
