“…Changing the 2D structure of MXene to other dimensional nanostructures is also an effective way to prevent the restacking or aggregation of MXene, thereby improving its electrochemical performance. In one study, the positively charged surfactant DODA (dimethyldioctadecylammonium bromide) was inserted between negatively charged MXene nanosheets through electrostatic interaction [ 82 ]. DODA not only prevented the restacking or aggregation of MXene nanosheets, but also combined with MXene to form an organic soluble MXene/DODA complex, which was further utilized to fabricate a 3D porous MXene nanostructure via the breath figure method ( Figure 3 ).…”

Neurotransmitters are chemical messengers that play an important role in the nervous system’s control of the body’s physiological state and behaviour. Abnormal levels of neurotransmitters are closely associated with some mental disorders. Therefore, accurate analysis of neurotransmitters is of great clinical importance. Electrochemical sensors have shown bright application prospects in the detection of neurotransmitters. In recent years, MXene has been increasingly used to prepare electrode materials for fabricating electrochemical neurotransmitter sensors due to its excellent physicochemical properties. This paper systematically introduces the advances in MXene-based electrochemical (bio)sensors for the detection of neurotransmitters (including dopamine, serotonin, epinephrine, norepinephrine, tyrosine, NO, and H2S), with a focus on their strategies for improving the electrochemical properties of MXene-based electrode materials, and provides the current challenges and future prospects for MXene-based electrochemical neurotransmitter sensors.

“…2D materials are usually easy to accumulate, which affects the rate performance of supercapacitors. [19,74,171c] In recent years, novel methods such as intercalation, [76] metal ions induction, [12f] and template, [172] have been utilized to improve the lamellar spacing and porosity of MXene to achieve excellent electrochemical performance. For instance, Chen et al fabricated crumpletextured Ti 3 C 2 T x (CT-MXene) to boost Mg 2+ -induced assembly for achieving conformal construction of Mg 2+ -MXene aerogels inspired by the skin structure of Phrynosoma cornutum.…”

Solid‐state energy storage devices (SSESDs) are believed to significantly improve safety, long‐term electrochemical/thermal stability, and energy/power density as well as reduce packaging demands, showing the huge application potential in large‐scale energy storage. Nevertheless, some key issues like low ionic conductivities, poor interface contact, and dendrites growth limit the practical application of SSESDs. In recent years, MXenes for SSESDs have received reassuring advances on account of unique parameters. Nevertheless, overall reviews about the subject are seldom. In this review, current advances of MXenes and their derivatives in solid‐state Li–metal, Li‐ion, Li–I/S, Na‐ion, Zn–air, Zn–metal batteries, and supercapacitors in cathode/anode optimization, interface medication, and electrolyte fillers, etc., are comprehensively reviewed. First of all, essential principles of MXenes are shown, such as precursors, etching/delamination strategies, as well as superior properties for energy storage systems. Meanwhile, the classification and evaluation parameters of solid‐state electrolytes are summarized. Subsequently, the application, modification mechanism, and design strategy of MXenes for boosting electrochemical behaviors of SSESDs are systematically reviewed and discussed. At last, perspectives and challenges about the future construction strategies of MXenes for SSESDs are recommended. This review shall assist scientists design and build advanced SSESDs with superior energy density along with safety.

“…Compared to hard templates, soft templates are usually liquid crystals, emulsions, micelles, etc. with low structural strength and stiffness and variable structure and shape. ,− More importantly, soft templates can often be removed by simple means, greatly simplifying the preparation steps, and are excellent template materials to help form MXene-based 3D structures with tunable pore sizes. Lu et al successfully reduced the hydrophilicity of Ti 3 C 2 T x by using electrostatic interactions between cetyltrimethylammonium bromide (CTAB) and MXene surface groups, so the modified Ti 3 C 2 T x could aggregate at the interface of oil and water phases.…”

With the rapid development of economics and society, the water pollution and water shortage problem is becoming more and more severe. Excellent 3D separation functional materials for efficient water purification are highly required, but their design and fabrication still remain a big challenge at present. Benefiting from distinct advantages, such as 2D nanolamellar structure, high hydrophilicity, abundant functional groups, and desirable mechanical strength, 2D transition metal carbide/nitride materials, MXenes, have afforded a new platform for the creation of 3D water treatment functional materials. This review summarizes recent progress in 3D MXene-based functional materials toward wastewater treatment and water reclamation. In this review, common fabrication approaches for 3D MXene structures are emphatically summarized and recent developments of 3D MXene functional materials focused on the capacitive deionization (CDI), solar desalination, adsorption, and photocatalytic degradation of pollutants are critically reviewed. Besides, the impact of the structural design on their material performance is outlined. The critical challenges of 3D MXene materials in the aforementioned fields are also highlighted. Finally, we provide a brief perspective on the future development of 3D MXene materials toward practical effluent treatments.
