Herein we report on the synthesis of two-dimensional transition metal carbides and carbonitrides by immersing select MAX phase powders in hydrofluoric acid, HF. The MAX phases represent a large (>60 members) family of ternary, layered, machinable transition metal carbides, nitrides, and carbonitrides. Herein we present evidence for the exfoliation of the following MAX phases: Ti(2)AlC, Ta(4)AlC(3), (Ti(0.5),Nb(0.5))(2)AlC, (V(0.5),Cr(0.5))(3)AlC(2), and Ti(3)AlCN by the simple immersion of…

MXenes: trends, growth, and future directions

Two-dimensional (2D) Ti3C2 discovery at Drexel University more than a decade ago created a new family of 2D transition metal carbides, nitrides, and carbonitrides [1]. Because top-down selective

Synthesis of Mo4VAlC4 MAX Phase and Two-Dimensional Mo4VC4 MXene with 5 Atomic Layers of Transition Metals.

This study demonstrates the existence of an additional subfamily of M5X4Tx MXenes as well as a twinned structure, allowing for a wider range of 2D structures and compositions for more control over properties, which could lead to many different applications.

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

Applications of 2D MXenes in energy conversion and storage systems.

The potential of MXenes for the photocatalytic degradation of organic pollutants in water, such as dye waste, is addressed, along with their promise as catalysts for ammonium synthesis from nitrogen.

Microscopic origin of MXenes derived from layered MAX phases

Two-dimensional transition metal carbides/nitrides Mn+1Xns labeled as MXenes derived from layered transition metal carbides/nitrides referred to as MAX phases attract increasing interest due to their

Fabrication of nanostructured functional materials using exfoliated nanosheets as a building block

A variety of layered transition metal oxides and layered double hydroxides have been exfoliated into unilamellar nanosheets such as Ti 0.91 O 2 , Ca 2 Nb 3 O 10 , MnO 2 , and M 1-x II Al x (OH) 2 (M

New MAX‐Phase Compounds in the V–Cr–Al–C System

New layered compounds, (V(0.5)Cr(0.5))(3)AlC(2), (V(0.5)Cr(0.5))(4)AlC(3), and (V(0.5)Cr(0.5))(5)Al(2)C(3) were synthesized by reactive hot pressing V, Cr, Al, and graphite powders. The crystal

Nanosheets of Oxides and Hydroxides: Ultimate 2D Charge‐Bearing Functional Crystallites

The charge-bearing inorganic macromolecule-like nanosheets can be assembled or organized through various solution-based processing techniques to produce a range of nanocomposites, multilayer nanofilms, and core-shell nanoarchitectures, which have great potential for electronic, magnetic, optical, photochemical, and catalytic applications.

The intercalation and exfoliation of tungsten disulfide

The exfoliation of WS2, the separation of this layer compound into single molecular layers suspended in solution, was found more difficult than the exfoliation of MoS2 reported earlier. The
