“…MXenes are a new branch of layered materials with fascinating electronic and optical properties and solution processability, allowing them to be widely used in various electronic and optoelectronic devices, such as transistors, photocatalysts, , photosensors, , and LEDs. , MXenes, including Ti 3 C 2 , MoC 2 , V 3 C 2 , and Ti 4 N 3 , are layered transition-metal carbides, nitrides, or carbonitrides that are produced when MAX phases exfoliate. MXenes are superior to Au nanoparticles as Schottky electrode materials because of their tunable work function (1.6–8.0 eV), outstanding optical transparency, and metallic conductivity. , As transparent Schottky contacts, MXenes have already been integrated with Si, GaAs, TiO 2 , perovskites, and so on.…”

ZnO nanomaterial-based UV photodetectors (UV PDs) have a long response time and poor responsiveness. The adjustable work function and high conductivity of 2D Ti 3 C 2 -MXene make it a suitable electrode material for optoelectronic devices. In this work, the MXene/ZnO nanorods Schottky junction hybrid was constructed via spin-coating of 2D Ti 3 C 2 -MXene nanosheets deposited on a 1D ZnO nanorods array, increasing the optical absorbance of the UV range. The MXene/ZnO nanorods PD at 368 nm and 5 V bias performs noticeably better with a high on/off ratio of 806, a responsivity of 142.2 mA W −1 , and a specific detectivity of 2.03 × 10 10 jones, which are, respectively, increased by 14.4, 418, and 4194 times than a pure ZnO nanorods PD,. In particular, the rise time and fall times of the MXene/ZnO nanorods PD at 5 V bias are 12.2 s/3.9 s, which are 31 and 76% faster than those of the ZnO nanorods PD, respectively. Developing 2D MXene/ZnO nanorods PDs provides an alternative strategy to improve the response rate and photoelectrical properties of ZnO nanorods PDs over conventional alloy solutions.

“…Since MXenes have a high surface area per unit weight and electrical conductivity and hydrophilicity are their fundamental properties, they have found potential applications, especially in energy storage [10]. The ability to adjust the surface terminals of this type of twodimensional materials has created a promising future in the preparation of thermoelectric devices [11], composites [12], photocatalysts [13], sensors, electrodes, batteries [14], nano-magnets, supercapacitors [15], and membranes. The semiconductor nature and unique physicochemical properties of these compounds have led to their use in photocatalysis in order to accelerate redox reactions such as hydrogen evolution reactions and other photocatalyst-based usages [16].…”

MXenes are known as a new type of two-dimensional layered materials that are composed of carbide, nitride, or carbonitride of transition metals. In the recent discovery of a new class of MXenes, two transition metals occupy the metal site, called double transition metal MXenes (DTM). These multilayer composites are of interest due to their attractive features such as high ion transport, extensive surface area, and biocompatibility. Some computational methods are used to predict the properties and performance of bimetallic carbonitrides. The most important feature of this category of materials is the stability and amount of formation energy, which directly affects the choice of material in various applications. Density functional theory (DFT) calculations are very beneficial to estimate the thermodynamic stability of DTM MXenes. Of course, proper surface modification with stable terminals is needed to overcome the limitations of DTM MXenes. In this review, the electrochemical, metallic, and magnetic properties of DTM MXene have been presented first. In the following, preparation methods are summarized according to the latest published findings. Then, various applications including hydrogen evolution reactions, anode materials in lithium and sodium batteries, nanomagnetic materials, and special applications have been investigated. Finally, more challenges, prospects, and suggestions for the development of two-dimensional DTM MXenes have been presented.

The pursuit of anode materials capable of rapid and reversible potassium storage performance is a challenging yet fascinating target. Herein, a heterointerface engineering strategy is proposed to prepare a novel superstructure composed of amorphous/crystalline Re2Te5 anchored on MXene substrate (A/C‐Re2Te5/MXene) as an advanced anode for potassium‐ion batteries (KIBs). The A/C‐Re2Te5/MXene anode exhibits outstanding reversible capacity (350.4 mAh g−1 after 200 cycles at 0.2 A g−1), excellent rate capability (162.5 mAh g−1 at 20 A g−1), remarkable long‐term cycling capability (186.1 mAh g−1 at 5 A g−1 over 5000 cycles), and reliable operation in flexible full KIBs, outperforming state‐of‐the‐art metal chalcogenides‐based devices. Experimental and theoretical investigations attribute this high performance to the synergistic effect of the A/C‐Re2Te5 with a built‐in electric field and the elastic MXene, enabling improved pseudocapacitive contribution, accelerated charge transfer behavior, and high K+ ion adsorption/diffusion ability. Meanwhile, a combination of intercalation and conversion reactions mechanism is observed within A/C‐Re2Te5/MXene. This work offers a new approach for developing metal tellurides‐ and MXene‐based anodes for achieving stable cyclability and fast‐charging KIBs.
