“…However, “conventional” two element M ‐site solid solution phases still exhibit large potential as just shown with the synthesis of (V 1‐x Cr x ) 2 GaC, [106] a solid solution phase almost matching the Stoner criterion. In general, the synthesis and characterization of M ‐site solid solution phases consisting of the early transition metals that MAX phases were initially known for, have enabled tailoring specific materials properties such as oxidation resistance, [107,108] mechanical characteristics, [103,109] or thermal properties [110] . Furthermore, the research area still holds a great potential as shown in recent literature reports [103,106] .…”

MAX phases are layered solids with unique properties combining characteristics of ceramics and metals. MXenes are their two‐dimensional siblings that can be synthesized as van der Waals stacked and multi‐/single‐layer nanosheets, which possess chemical and physical properties that make them interesting for a plethora of applications. Both families of materials are highly versatile in terms of their chemical composition and theoretical studies suggest that many more members are stable and can be synthesized. This is very intriguing because new combinations of elements, and potentially new structures, can lead to further (tunable) properties. In this review, we focus on the synthesis science (including non‐conventional approaches) and structure of members less investigated, namely compounds with more exotic M‐, A‐, and X‐elements, for example nitrides and (carbo)nitrides, and the related family of MAB phases.

“…A few other examples have been reported. Cai et al [48] synthesized Nb3.9W0.1AlC3 but only 2.5% of Nb was substituted by W. Similarly, Wang et al [49] synthesized (Ti1-xWx)3SiC2 but reported that only 5 mol.% W could be incorporated into the MAX phase. Furthermore, although Si-based MAX phases serve as MXene precursors [50] , it is much more convenient to have Al-based MAX phases that are easier to selectively etch.…”

One of the distinguishing features of MAX phases and their MXene derivatives is their remarkable chemical diversity. This diversity, coupled with the two-dimensional nature of MXenes, positions them as outstanding candidates for a wide range of electrochemical applications. In this study, we report the synthesis of M site T1-xWx solid solution MAX phases, specifically (Ti1-xWx)2AlC and (Ti1-xWx)3AlC2. The 211-type phase exhibited a disordered solid solution, whereas the 312-type phase displayed a more ordered structure, resembling an o-MAX arrangement, with W atoms preferentially occupying the outer planes. This specific ordering in the 312-type MAX phase is attributed to the unique electronic structure and atomic radius of W, indicating that these characteristics are crucial for the preferential occupation of the outer planes. Moreover, corresponding solid-solution MXenes, Ti2.4W0.6C2Tz and Ti1.6W0.4CTz, were synthesized via selective etching of MAX powder precursors containing 20% W. These MXenes were evaluated as sodium-ion battery anodes, with Ti1.6W0.4CTz showing exceptional capacity, outperforming existing multilayer MXene chemistries. This work not only demonstrates the successful integration of W in meaningful quantities into a double transition metal solid solution MAX phase, but also paves the way for the development of cost-effective MXenes containing W. Such advancements significantly widen their application spectrum by fine-tuning their physical, electronic, mechanical, electrochemical, and catalytic properties.

A distinguishing feature of MAX phases and their MXene derivatives is their remarkable chemical diversity. This diversity, coupled with the 2D nature of MXenes, positions them as outstanding candidates for a wide range of electrochemical applications. Chemical disorder introduced by a solid solution can improve electrochemical behavior. Up to now, adding considerable amount of tungsten (W) in MAX phase and MXenes solid solutions, which can enhance electrochemical performance, proved challenging. In this study, the synthesis of M site Ti1‐xWx solid solution MAX phases are reported. The 211‐type (Ti1‐xWx)2AlC exhibits a disordered solid solution, whereas the 312‐type (Ti1‐xWx)3AlC2 displays a near‐ordered structure, resembling o‐MAX, with W atoms preferentially occupying the outer planes. Solid‐solution MXenes, Ti2.4W0.6C2Tz, and Ti1.6W0.4CTz, are synthesized via selective etching of high‐purity MAX powder precursors containing 20% W. These MXenes are evaluated as sodium‐ion battery anodes, with Ti1.6W0.4CTz showing exceptional capacity, outperforming existing multilayer MXene chemistries. This work not only demonstrates the successful integration of W in meaningful quantities into a double transition metal solid solution MAX phase, but also paves the way for the development of cost‐effective MXenes containing W. Such advancements significantly widen their application spectrum by fine‐tuning their physical, electronic, mechanical, electrochemical, and catalytic properties.
