Electronic properties and applications of MXenes: a theoretical review

“…Experimentally, MXenes have already found applications as transparent conductors [18][19][20], field effect transistors [21], supercapacitors [22][23][24], Li ion batteries [25,26], electromagnetic interface shielders [27], fillers in polymeric composites [28], hybrid nanocompositites [29], purifiers [30,31], dual-responsive surfaces [32], suitable substrates for dyes [33], catalysts [34,35], promising materials for methane storage [36], and photocatalysts for hydrogen production [37], as well as being ceramic biomaterials with high photothermal conversion efficiency for cancer therapy [38]. Theoretically, many applications have been proposed for MXenes in electronic [39][40][41][42][43], magnetic [44][45][46][47][48], optical [49,50], thermoelectric [51][52][53][54][55][56], and sensing devices [57], as well as being new potential materials for catalytic and photocatalytic reactions [58][59][60]…”

MXene‐Based Composites: Synthesis and Applications in Rechargeable Batteries and Supercapacitors

“…After etching of the A layer (1), the majority of obtained M n+1 X n will continue to interact with H 2 O (2) and HF (3) to form a functional group-containing surface. The surfaces of MXenes fabricated by selective etching by HF carry miscellaneous functional groups (OH, F, O, and H).…”

“…For example, Wang and coworkers modified a poly(o-phenylenediamine) (PoPD) with silver nanoparticles (Ag NPs) to form the PoPD/Ag composite as a glucose sensor material. By this method, metal NPs can be deposited on the surface of MXenes from their corresponding precursors, such as AgNO 3 , [216] HAuCl 4 , [59] PdCl 2 , [59] HPtCl 6 , [3] RuCl 3 , [217,218] NiCl 2 , [218] CoCl 2 , [3,217] etc. [214] Zhang et al used density functional theory (DFT) to explore the properties of a Ti/Ti 2 CO 2 composite, which shows better activity than precious metals in catalyzing CO oxidation.…”

“…Via different deposition times, nanoparticles or nanowires could be formed on the MXene surface ( Figure 7i). [3,217,218] On the other hand, this method could also be applied to the preparation of pure metals. [219] Moreover, a noble metal's many empty orbitals, which provide the condition for formation of coordinative bonds, lead to the modification of decorated metal nanoparticles, improving the corresponding properties of the final composite.…”
