Ti₃C₂T_x MXene: A New Promising 2D Material for Optoelectronics

Abstract

MXenes are the new members in the family of two-dimensional (2D) layered materials composed of transitional metal carbides, nitrides, or carbonitrides. Among all other MXenes, Ti3C2T x MXene is the most studied one due to the exceptional properties that make it suitable for various applications, including optoelectronics. Ti3C2T x MXene can be fabricated and processed in a variety of scalable and cost-effective ways. MXenes are solution-processable materials that can be deposited by spin, spray, or dip coating, painting, or printing. They exhibit excellent optical transparency, high metallic conductivity, efficient photothermal conversion, plasmonic behavior, and tunability of the optical response over traditional 2D materials. These features have led to a fast evolution of this material with many explorations of its applications in the field of optoelectronics. This short review summarizes the recent updates on the synthesis, optical, as well as electronic properties, and the various optoelectronic applications of Ti3C2T x MXene in the materials point of view. The challenges to be overcome for their successful integration into the optoelectronics domain and opportunities for future explorations are also discussed.

Recent developments in the state-of-the-art optoelectronic synaptic devices based on 2D materials: a review

“…Like BP, MXenes are also vulnerable to oxidation. 175 Transition metal dichalcogenides (TMDCs), MX 2 , where M = transition metals (Mo, W, etc. ) and X = chalcogens (S, Se, Te), have also shown promising results in optoelectronics due to their strong light absorption properties.…”

CO2 Photoreduction over Semiconducting 2D Materials with Supported Single Atoms: Recent Progress and Challenges

“…Among Mxenes, Ti 3 C 2 T x was the first compound reported in 2011, [142] followed by approximately 30 new compositions with the general formula M n+1 X n T x , where M signifies an early transition metal (Ti, Zr, Hf, V, Sc, Y, V, Nb, Ta, or Mo, etc . ), X depicts C and/or N, and T x denotes functional groups (−OH, −F, −O, and −Cl) terminating the M surface [144] . Certain forms of Ti 3 C 2 T x , especially when functionalized with specific groups, may exhibit semiconducting behavior, rendering them potentially useful for photocatalysis [145–149] .…”
