Ti3C2Tx Mxene Multilayer Nanoflakes MXene Phase

Ti3C2Tx MXene Multilayer Nanoflakes:
Ti3C2Tx is a member of the MXene family, a class of two-dimensional (2D) materials known for their impressive electrical, thermal, and mechanical properties. These materials are characterized by their layered structure, which can be exfoliated into thin nanoflakes. The “Ti3C2Tx” designation refers to a specific MXene where titanium (Ti) atoms are bonded to carbon (C) atoms, and the “Tx” represents surface terminations that can include various functional groups like -O, -OH, or -F.Ti3C2Tx MXenes are being explored for their potential in improving the performance of batteries, supercapacitors, and other electronic components. The ability to manipulate the number of layers and the surface chemistry of these nanoflakes allows for fine-tuning their properties for specific uses.
Structure and Phase Characteristics
Layered Structure:
mxene phase consist of titanium (Ti) and carbon (C) layers interspersed with surface terminations (Tx), which could be -OH, -O, or -F groups. The “3” indicates three titanium atoms, and “2” denotes two carbon atoms in the formula unit. Multilayer Nanoflakes: In the multilayer form, mxene phase are composed of several stacked nanoflakes.
Exfoliation processes: such as selective etching or chemical treatments, can produce multilayer MXene nanoflakes from bulk materials. The process typically involves removing the aluminum layer from the parent MAX phase (e.g., Ti3AlC2) to obtain the Ti3C2Tx MXene multilayer nanoflakes.
Phase Behavior: The phase behavior of Ti3C2Tx can be influenced by factors like the choice of surface terminations, the number of layers, and the presence of intercalants. The electronic properties and stability of these MXenes can vary with changes in their phase composition.
Applications: Ti3C2tx mxene multilayer nanoflakes are used in various applications, including energy storage devices (supercapacitors and batteries), sensors, and advanced composites. Their high electrical conductivity and surface area make them suitable for these roles.
