Abstract
This review paper is focused on the electrical and magnetic property based applications of MXenes such as cancer theranostics, spintronics, and shielding against electromagnetic pollution.
Highlights
The tremendous amount of research increased after 2011 when the first two-dimensional titanium carbide (Ti3C2Tx) was discovered by treating the MAX precursor Ti3AlC2 with hydrogen fluoride (HF) solution as the etchant.[20,21]
Hart and coworkers studied the electronic properties of MXenes through termination and intercalation. They found that transitions between metallic and semiconductor behavior were induced through intercalation, while de-functionalization of the surface of the MXenes gave rise to increased electronic conductivity.[62]
It was proposed that direct magnetic exchange between surface Z and Ti atoms induces the larger magnetism in the doped systems.[144]
Summary
The exfoliation of the first two dimensional (2D) material in 2004, known as graphene, opened up the door for searching for other 2D materials such as hexagonal boron nitride (h-BN), silicon and germanium counterparts, transition metal dichalcogenides (TMDs), transition metal carbides (TMCs)/nitrides (TMNs), etc.[1,2] In this direction, various 2D materials such as silicene (2D allotrope of silicon),[3,4,5] germanene (2D allotrope of germanium),[6] molybdenum disulfide (2D TMD),[7,8] phosphorene (2D black phosphorous),[9,10,11] and many more have been studied so far.[12,13,14,15] The 3D carbide and nitride counterparts that contain. Group IV–VI transition metals were discovered in the 20th century.[16,17,18] These materials are known to possess good chemical stability, hardness, high thermal and high mechanical stability, and wear-resistant properties.[19] The tremendous amount of research increased after 2011 when the first two-dimensional titanium carbide (Ti3C2Tx) was discovered by treating the MAX precursor Ti3AlC2 with hydrogen fluoride (HF) solution as the etchant.[20,21] The 2D layered transition metal carbides, nitrides, and carbonitrides are named MXenes, and have the formula Mn+1Xn (n = 1–3) where n + 1 layers of M cover n layers of X.22. Review comprise close-packed and alternative stacking of planar atomic layers and MX hexagonal layers In this framework, the M–X and M–A bonds indicate the ionic/covalent and metallic characteristics. Several research papers and reviews discussing photonics, optoelectronics, photothermal therapy, energy conversion, and storage applications of 2D MXene based materials have been reported.[25,42,43,44,45,46,47,48,49,50] The present review paper discusses the electric and magnetic properties of MXene based composites and recent progress in MXene composites for biomedical applications, spintronics and protection from electromagnetic pollution
