In Situ Growth of Three‐Dimensional MXene/Metal–Organic Framework Composites for High‐Performance Supercapacitors

“…MOFs have the advantages of high specific surface area, ultrahigh porosity, tunable pore size, multiple functionalities, and diversity in redox metal centers [1–4] . Consequently, MOFs have been widely used in several functional applications, such as gas storage, [5, 6] drug delivery, [7] chemical sensing, [8] catalysis, [9–11] and energy conversion [12–14] . However, the conductivity of traditional MOFs is not ideal, which limits their application in energy storage that requires excellent conductivity [15, 16] .…”

Coordination bond cleavage of metal–organic frameworks and application to flame-retardant polymeric materials

“…MOFs-derived hollow structures, yolk@shell structures, and laminated structures expose more active sites, as well as faster mass transport through complete or incomplete conversion compared to bulk MOFs. 81,82 Such peculiar structures can be fabricated by either transition metal salt etching or acid/base etching strategies under certain reaction conditions, and the detailed principles have been elaborated as above. Flame retardants with single yolk@shell structures and multi-yolk@shell structures are rarely reported in the flame retardant field due to their sophisticated synthesis.…”

Morphological Anisotropy in Metal–Organic Framework Micro/Nanostructures

“…reported the synthesis of MIL‐101 nanocrystals with a core–shell like structure, where more defects are generated in the core than in the shell [30] . It should be noted that most reported MOF MNPs are homogeneous in structure due to high crystallinity; [31] thus examples of morphology‐independent anisotropy are significantly rarer than morphology‐dependent anisotropy. It is postulated that morphology‐independent anisotropy may exist in MOF MNPs grown through fast nucleation and crystal growth with reduced crystallinity.…”
