“…After the introduction of vacancy, it can be found that Mo 3d, P 2p, and Ru 3p in the Ru-Mo-P V shift to low binding energies (Figure b–d) due to Mo and Ru valences decreasing after NaBH 4 treatment, and the P can achieve more electrons. For Mo 3d in Ru-MoP-P V (Figure b), the peaks at 228.2, 230.9, 231.4, and 234.5 eV are attributed to Mo δ+ (0< δ < 4) species of MoP. − The characteristic peaks at 232.9 eV and 236.3 eV are attributed to Mo 6+ due to the slight oxidation of MoP in the air. , For P 2p, the peaks at around 129.5 eV/130.4 eV are assigned to the Mo–P bond, , and the peak of P–O is located at 133.6 eV (Figure c). For Ru 3p, the peaks at 461.4 and 483.7 eV are assigned to Ru (0) , (Figure d).…”

Molybdenum phosphide (MoP) has received increasing attention for the hydrogen evolution reaction (HER) due to its Pt-like electronic structure and high electrical conductivity. In this work, a flake-like Ru-doped MoP with phosphorus vacancy (Ru-MoP-P V ) electrocatalyst is synthesized for the first time by a simple and rapid room-temperature microwave approach within 30 s. The created abundant phosphorus vacancies provide rich active sites and favor rapid electron transfer. The introduced Ru also enhances the catalytic activity of the synthesized electrocatalyst efficiently. Then, the designed Ru-MoP-P V possesses low overpotentials for HER with 79, 100, and 161 mV in 1.0 M KOH, 0.5 M H 2 SO 4 , and 1.0 M phosphatebuffered saline to obtain 10 mA cm −2 . The Ru-MoP-P V and NiFelayered double hydroxide are used as the cathode and the anode, respectively, to drive water splitting and just need a low cell voltage of 1.6 V to achieve 10 mA cm −2 . This work provides a feasible way for the rapid production of metal phosphides for energy conversion and storage applications.

“…The as synthesized MXene has a lamellar microstructure and comparable XRD peaks with HF-etched MXene. The reaction follows the following chemistry: where A can be Si or Ge, n = 2-4 and m = 3-4) using UV etching [122]. This selective etching technique using concentrated phosphoric acid to obtain Mo 2 CT x after 3-4 h of UV exposure caused lattice rearrangements and oxidation of Mo 2+ species.…”

“…The instinct is that the non-MAX phase materials like MoInC or Mo 2 Ga 2 C result in the synthesis of Mo 2 CT x (MXenes), which exhibits a similar structure produced from the MAX phase precursor like Mo 2 GaC. [22][23][24][25] Hence, it is not astonishing that the same kind of MXene can be produced from different optimal precursors. Similarly, the combined structure of quaternary materials in the general formula of MAX Phase (M n+1 AX n ), with the combination of pure or mixture of M, A, and X sublattices, are called i-MAX precursors.…”

Two-dimensional materials have garnered significant attention in recent years due to their unique physical and chemical properties, making them promising candidates for advanced electronic technologies. Graphene, in particular, has shown extraordinary qualities with the potential for highly efficient and durable electronic devices, overcoming technological limitations associated with downsizing. However, the absence of a band gap in graphene's structure has led researchers to explore alternative materials for transistor applications. MXene and its derivatives were developed in response to this shift in emphasis as potential solutions for constructing electronic systems. Simple changes in surface termination, the introduction of metal ions, careful management of etching duration, and suitable surface functionalization can improve the characteristics of MXene, which are similar to those of graphene. These modifications result in the desired band structure, enabling advanced applications. This review provides an overview of the most recent advancements in MXene-based materials design, highlighting challenges and future prospects, specifically focusing on the efficient design of field-effect transistor (FET) gas sensing devices. The underlying goal is to familiarize the readers with the MXene in FET-based sensing applications and summarize recent development in this field to transition to next-generation electronic devices.
