Abstract
The sequence of 2D transition metal carbides, carbonitrides, and nitrides has gained a lot of interest since the discovery of Ti3C2. About thirty new MXene compounds have been identified, with eight different MXene synthesis methods. The presence of surface terminations such as hydroxyl, oxygen, fluorine, or chlorine in the materials described thus far indicates strong hydrophilicity as well as metallic conductivity MXenes are becoming increasingly popular due to their diverse chemistry, which has sparked a surge in academic interest. We will study and examine the many methods of fabricating MXenes in this review, which will cover everything from MAX phase etching to exfoliation, as well as the best approach to synthesise them and their most current applications.

Superficial endings like hydroxy, fluorine and oxygen are mainly inserted during MXene synthesis, and predict functional properties, like catalytic performance, magnetism, Li-ion capacity, mechanical properties, to predict superconductivity, when the metal is controlled by insulating transition and subsidising.[65-75]
2.2 Synthesis of MAX phases: The MXE precursors i.e. the MAX phases can be synthesised through a variety of methods, e.g. chemical vapour deposition (CVD) by combustion at different temperatures,[101] high temperature self propagering synthesis (HTS), plasma spark sintering, molten salt or isostatic hot pressure reaction or mechanical alloying, which can speed the A-layer removal
Summary
Crystallized solids having a thickness of a few atoms or fewer are known as two-dimensional materials. The discovery of graphene, the most well-known twodimensional (2D) substance, has sparked a renewed interest in two-dimensional (2D) materials among scientists.[1]There are numerous 2D materials available, each with its own set of characteristics. 2D transition metal dichalcogenides (e.g. MoS2, MoSe2, WS2), hexagonal boron nitride, metal oxides, black phosphorus (BP), silicene (2D silicon), MXenes (2D carbides/nitrides), borophene (2D boron), and germanene (2D boron) are some of these (2D germanium) [2-9]. 2D materials can have diverse optical characteristics, based on their chemical compositions as well as structural configurations MXenes, graphene, NbSe2 etc), semi metallic behaviour (for example.PtSe2, TiS2), semiconducting 2D materials may be metallic (e.gn, graphene, NbSe2 etc.) or even superconducting (e.g. moisture 2), (e.g. moisture 2), (e.g. MoS2, WSe2), (hexagonal boron nitride), (e.g. NbS2) and feature varying optical characteristics based on their chemical compositions as well as structural configurations.[10-15]. MXenes has different features, which provide exciting avenues for 2D materials and
