MXenes vs. clays: emerging and traditional 2D layered nanoarchitectonics

“…In this way, replacing clay by MXenes in carbon-clay materials by applying top-down and bottom-up methodologies, it is expected to obtain higher conducting materials. In this way, MXene-carbon composites can be prepared from polymers such as PAN 219 and block copolymer P123/melamine–formaldehyde resin, 122 or from carbon gases such as ethene, 220 obtaining carbon nanofibers, mesoporous carbons and CNT, respectively, assembled on the MXenes. As well, these composites have been obtained from the intimate mixture of the carbon particles and the MXenes, as a top-down process, by dispersion in the liquid phase of graphene 221,222 or CNT 223 and MXenes, or by direct grinding of these components.…”

Evaluating the electrocatalytic activity of flower-like Co-MOF/CNT nanocomposites for methanol oxidation in basic electrolytes

“… 8,14 To overcome these drawbacks, and enhance their surface area and conductivity, MOFs have been mixed with conductive carbon-supporting materials, such as graphene, graphene oxide (GO), porous carbon, carbon quantum dots, and carbon nanotubes (CNTs), in intriguing composites to enhance their electrical conductivity and ion transferability. 15,16 Among all carbon materials, CNTs are recognized as having high potential as a carbon support material due to their high surface area, distinct catalytic characteristics, and high electrical properties. Dual composite CNT-based MOFs display synergistic features from both components, resulting in improved electrochemical activity, due to their enhanced conductivity, increased electroactive sites for reaction, short diffusion path for ions, and abundant redox reactions in basic electrolytes.…”
