Enhanced thermoelectric performance in MXene/SnTe nanocomposites synthesized via a facile one-step solvothermal method

Interfacial modulation to achieve low lattice thermal conductivity and enhanced thermoelectric performance in n-type Mg3(Sb, Bi)2-based materials via graphene and MXene

“…31,32 More specifically, the Ti–C and Ti–F bonds can confirm the existence of MXene and are attributed to the C–TiO bonds in Ti 3 C 2 T x and Ti–F bonds etched from HF, respectively. Additionally, the presence of Ti–O and TiO bonds in the x = 0.6 M sample indicates a gradual oxidation of the MXene to TiO 2 , 27 which should be considered and reduced to minimize deterioration during the synthesis process.…”

“…S1 †). 26,27 Specically, 2 g of Ti 3 AlC 2 (98%, Aladdin) was added to the etchant consisting of LiF (2 g) and HCl (40 ml of 9 M) and kept stirring for 24 h at 308 K. Then, the collected products were washed repeatedly with deionized water by centrifuging until the pH value of the supernatant reached ∼6. Next, the above precipitates were sonicated in deionized water and centrifuged at 3500 rpm for 10 minutes.…”

Advances in Thermoelectric Composites Consisting of Conductive Polymers and Fillers with Different Architectures

“…It should be noted that most MXene is metallic, but some MXene with M as Ti, Hf, Cr, Mo, Sr, Y, and W can exhibit semiconducting properties, so only these semiconducting MXene have some TE properties. In addition, due to the special structure of MXene, they are able to be made into n-type [ 93 , 110 , 111 , 112 ].…”

High Thermoelectric Performance in Ti3C2Tx MXene/Sb2Te3 Composite Film for Highly Flexible Thermoelectric Devices

“…Other inorganic materials' thermoelectric properties can be modulated by MXene, such as Ti 3 C 2 T x . [23][24][25][26] Lu et al compounded MXene with (Bi, Sb) 2 Te 3 , exhibiting excellent thermoelectric properties (zT of 1.23). After the addition of MXene, the Seebeck coefficient was basically unchanged, while the electrical conductivity was significantly increased.…”
