“…Nafion was also applied to deposit MXene with adsorbed hemoglobin [29], MXene/ Mn 3 (PO 4 ) 2 hybrid particles [30] or MXene/TiO 2 mixed with hemoglobin on GCE [31]. Furthermore, Nafion has a beneficial role in resisting interferences coming from negatively charged redox species such as ascorbic acid [32]. Nafion was also used as a glue to deposit MXene modified by APTES applied to deliver À NH 2 functional groups on the surface of MXene for a final construction of an immunosensor [33].…”

“…MXene should be applied for the construction of electrochemical biosensors operating especially in a cathodic potential window since MXene can be irreversibly oxidized at potential of + 0.4 vs. Ag/ AgCl (3 M KCl) with a dramatic alteration of the redox behaviour of MXene [44]. Stability of MXene for operation in a cathodic potential window can be enhanced to some degree by deposition of PtNPs on MXene [32,45].…”

MXenes are a new group of 2D nanomaterials with fascinating properties including high electrical conductivity, hydrophilic nature, easily tunable structure and high surface area. This is why MXene modified interfaces are extremely promising for the preparation of sensitive electrochemical biosensors. While there are numerous reports on MXene‐based enzymatic biosensors for detection of a wide range of analytes, application of MXene for construction of affinity biosensors is in its infancy. The review article summarizes current state‐of the‐art in the field with a focus on MXene modifications needed for construction of robust and high performance MXene electrochemical biosensors.

The family of 2D transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) is rapidly studied since the initial synthesis of Ti3C2Tx (MXene). The surface of MXenes etched by hydrofluoric acid has hydrophilic groups (F, OH, and O), which leads the surface to be negatively charged. Consequently, the negatively charged surface can facilitate the compounding of MXenes with other positively charged materials and prevent MXenes from aggregating with some negatively charged substances, thus promoting the formation of a stable dispersion. The MXene‐based composites have better electrochemical performance than both precursors due to synergistic effects. This review elaborates and discusses the development of MXene‐based composites. It is aimed to summarize the various methods of fabricating MXene‐based composites. The applications of MXene‐based composites in batteries and supercapacitors are presented along with analysis of their excellent electrochemical performances. Finally, the authors propose the approach for further enhancing the electrochemical performances of MXene‐based composite electrode materials.

“…[24,26,27] Currently, a new family of 2D early transitionmetal carbides (MXenes) is synthesized by selectively etching an element from the MAX phases (M n+1 AX n , where n = 1 to 3, M is an early transition metal. [33,36,37] In the thermal decomposition of ammonium perchlorate, MXene─Cu 2 O exhibits more excellent catalytic performance than MXene and Cu 2 O alone. [30][31][32][33][34][35] For example, Ag, Pt, and Pd@MXene Hybrids of superior stability are successfully synthesized with wide application in electrochemistry.…”

The direct conversion of methane to methanol remains a great challenge due to the difficulty of methane activation. Based on density functional theory calculations, the adsorption property and structure stability of supported Pd monomer and dimer are compared, and then Mo 2 CO 2 (MXene)-supported Pd dimer is chosen as a catalyst to study the process of methane partial oxidation to methanol via oxygen dissociation, proton transfer, and hydrogen spillover reaction pathways, respectively. Calculation results show that, unlike Pd monomer, Pd dimer can provide the multiple adsorption sites for activation and adsorption of methane and oxygen, which is beneficial for the direct process of methane to methanol. Notably, the proton transfer pathway of undissociated oxygen with rate-determining step of C-H bond dissociation can easily occur on Pd 2 /Mo 2 CO 2 . And this process avoids the extra energy required for oxygen dissociation. Our calculations provide a new design strategy with supported Pd dimer catalyst for direct methane conversion into methanol.
