2D metal carbides and nitrides (MXenes) for energy storage
The family of 2D transition metal carbides, carbonitrides and nitrides (collectively referred to as MXenes) has expanded rapidly since the discovery of Ti3C2 in 2011. The materials reported so far…
Guidelines for Synthesis and Processing of Two-Dimensional Titanium Carbide (Ti3C2Tx MXene)
Two-dimensional (2D) transition metal carbides, carbonitrides, and nitrides (MXenes) were discovered in 2011. Since the original discovery, more than 20 different compositions have been synthesized…
Electromagnetic interference shielding with 2D transition metal carbides (MXenes)
The mechanical flexibility and easy coating capability offered by MXenes and their composites enable them to shield surfaces of any shape while providing high EMI shielding efficiency.
The Rise of MXenes.
Synthesis of two-dimensional titanium nitride Ti4N3 (MXene).
The first two-dimensional transition metal nitride, Ti4N3-based MXene is synthesised using a molten fluoride salt to etch Al from a Ti4AlN3 powder precursor at 550 °C under an argon atmosphere and delaminated the resulting MXene to produce few-layered nanosheets and monolayers of Ti4n3Tx.
Two-Dimensional, Ordered, Double Transition Metals Carbides (MXenes).
DFT is used to predict the existence of two new families of 2D ordered, carbides, M'2M″C2 and M' 2M″2C3, where M' and M″ are two different early transition metals, offering additional choices of structures, chemistries, and ultimately useful properties.
Elastic properties of 2D Ti3C2Tx MXene monolayers and bilayers
This work opened a pathway for investigating the mechanical properties of monolayers and bilayers of other MXenes and extends the already broad range of MXenes’ applications to structural composites, protective coatings, nanoresonators, and membranes that require materials with exceptional mechanical properties.
