“…Nevertheless, bare MXenes oxidise very quickly, so realistically the best capacities are found in O‐ (which can adsorb multiple layers of Li), followed by HO‐ and F‐terminated MXenes (with the exception of special cases where normal functional groups have been substituted by another element or molecule such as Si) . This hierarchy of capacities is quite convenient for those who perform fluorine‐free MXene syntheses, as OH terminations can be removed by lithiation (which occurs during initial charge of a Li‐ion battery) or annealing, and potentially be substituted by O terminations.…”

2D transition metal carbides and nitrides (MXenes) are electrochemically active materials capable of exhibiting pseudocapacitance. Multilayer MXenes are similar to graphite, but with larger interlayer spacing and surface functionalities which allow them to readily disperse in water and undergo a range of reactions without compromising their electrical conductivity. The large interlayer spacing enables MXenes to readily intercalate large ions, and form composites with materials such as graphene, metal oxides, transition metal dichalcogenides and silicon, with which they make electrodes able to deliver exceptional capacities at high power rates over thousands of cycles. Research into MXenes for energy storage has grown exponentially since 2011, and it is now necessary, especially for readers new to the field, to review progress made in more specific areas. This critical review will therefore analyse the progress made in developing MXene‐based batteries, focusing solely on anodes developed for metal‐ion batteries such as Li‐ion, Na‐ion and K‐ion.

Since the "birth" of graphene in 2004, two-dimensional (2D) materials have attracted unprecedented research interest from scientists and have stimulated numerous applications in various fields, such as electronic/optical devices, energy storage, catalysis, sensors, and biomedicine. In this review, we summarize recent advances in the antimicrobial applications of 2D materials, such as graphene materials (GMs), layered double hydroxides (LDHs), transition-metal dichalcogenides (TMDs), graphitic carbon nitride (g-C N ), MXenes, black phosphorus (BP), and their derivatives. This review also correlates the unique physicochemical properties of 2D materials with their antimicrobial activities. Finally, some current challenges and future perspectives in this field are also presented.

“…Ghidiu et al used less harmful HCl/LiF etchant to dissolve aluminum and extract carbide layer . The fluorine‐free methods were reported by Xuan et al and Yu et al, who delaminated MXene NSs using organic base intercalation and the strong absorption was observed to remain . The optimization of fabrication strategy of MXene would further promote its promising application in water treatment.…”

Water shortage and the energy crisis are two major global challenges in this century. The solution for water crisis should be based on a sustainable energy source. Solar‐inspired water purification is an efficient and green technology for tackling the water challenge using abundant and clean solar energy through photothermal evaporation‐induced water production, photoinduced antimicrobial treatment, and photocatalytic degradation of organic contaminants. 2D nanomaterials draw significant attention for their use these three water‐purification methods because of their large surface area, broadband and strong absorption in the solar spectral range, and efficient photothermal and photocatalytic transformation. Herein, the recent development of 2D nanomaterials applied in photothermal evaporation, photoinduced antimicrobial treatment, and photocatalytic capability is comprehensively overviewed. Various strategies in enhancing the light‐absorption and light‐conversion efficiency for different 2D nanomaterials are presented. The challenges and perspectives of these 2D nanomaterials are further discussed for practical water purification. This Review highlights these green energy–driven water‐purification methods based on emerging 2D materials.
