“…Owing to the increased electrolyte accessible surface area and the additional contribution of pseudocapacitance caused by the MnO 2 , the obtained MnO 2 /Ti 3 C 2 T x composite achieved a specific capacitance of 212 F g −1 , nearly three times higher than that of pristine Ti 3 C 2 T x . Afterward, various transition metal oxides, such as TiO 2 , ZnO, MoO 3 , NiO, and MnO x , were used to form composites with Ti 3 C 2 T x to enhance the electrochemical performance .

Ti C T , a typical representative among the emerging family of 2D layered transition metal carbides and/or nitrides referred to as MXenes, has exhibited multiple advantages including metallic conductivity, a plastic layer structure, small band gaps, and the hydrophilic nature of its functionalized surface. As a result, this 2D material is intensively investigated for application in the energy storage field. The composition, morphology and texture, surface chemistry, and structural configuration of Ti C T directly influence its electrochemical performance, e.g., the use of a well-designed 2D Ti C T as a rechargeable battery anode has significantly enhanced battery performance by providing more chemically active interfaces, shortened ion-diffusion lengths, and improved in-plane carrier/charge-transport kinetics. Some recent progresses of Ti C T MXene are achieved in energy storage. This Review summarizes recent advances in the synthesis and electrochemical energy storage applications of Ti C T MXene including supercapacitors, lithium-ion batteries, sodium-ion batteries, and lithium-sulfur batteries. The current opportunities and future challenges of Ti C T MXene are addressed for energy-storage devices. This Review seeks to provide a rational and in-depth understanding of the relation between the electrochemical performance and the nanostructural/chemical composition of Ti C T , which will promote the further development of 2D MXenes in energy-storage applications.

Two kinds of Ti 3 C 2 /TiO 2 hybrids were synthesized by room temperature oxidation methods, named as Ti 3 C 2 /TiO 2 -nanoparticles and Ti 3 C 2 /TiO 2 -nanowires, respectively. Effects of reaction time and concentration of NaOH solution on the microstructures and electrochemical performances of Ti 3 C 2 /TiO 2 composites were studied in details. When used as electrodes for supercapacitors, both Ti 3 C 2 /TiO 2 -nanoparticles and Ti 3 C 2 /TiO 2 -nanowires exhibit enhanced supercapacitive performances. The electrochemical measurement results show that the specific capacitances of Ti 3 C 2 /TiO 2 -nanoparticles and Ti 3 C 2 /TiO 2 -nanowires electrodes are 128 and 143 F/g at 2 mV/s, respectively, which are larger than that of Ti 3 C 2 MXene (91 F/g). Furthermore, after 6000 charge-discharge cycles at 5 A/g, 88% and 80% of the initial capacitances are retained for Ti 3 C 2 /TiO 2 -nanoparticles and Ti 3 C 2 /TiO 2 -nanowires, respectively. Therefore, this work not only enhances the understanding of the surface states and morphology structures of Ti 3 C 2 MXene at different reaction condition in the aqueous solutions, but also provides simple and facile ways to fabricate photocatalysts, 5-8 lithium-ion batteries 9-11 and supercapacitors. 12-14MXenes are produced by selective etching of "A" layers from M n+1 AX n (n = 1, 2, 3) phase, where M belongs to an early transition metal, A represents a IIIA or IVA element, and X is C and/or N. [15][16][17] The structures of the etched resultants are similar to the exfoliated graphite.15 Typically, MXenes are terminated by -OH, -O and/or -F surface groups (denoted as T x ), and so their general formula is M n+1 X n T x , 15,17,18 such as Ti 3 C 2 T x and Ti 2 CT x . MXenes show significant potential in energy storages benefiting from their layered structure, hydrophilic surfaces, outstanding electrical conductivity and excellent chemical stability. 10,12,13,[17][18][19][20] MXene-derived nanoribbons, formed in simultaneous oxidation and alkalization processes, also show high-performances in sodium and potassium ion batteries. 21 In addition, the electrochemical properties of MXenes and MXenesbased materials have been extensively investigated in aqueous 13,22,23 and nonaqueous electrolytes. 24,25 Notably, MXenes have been demonstrated to exhibit large pseudocapacitance, which is caused by ion intercalation between their two-dimensional nanosheets. 26,27 In order to satisfy the increasing strict requirements of energy storage devices, MXenes are motivated to exploit much better electrochemical performances. Recent studies reported that introduction of transition metal oxides into MXenes is an efficient way to improve the electrochemical properties in supercapacitors 28-31 and lithium-ion batteries 32,33 . Among the transition metal oxides, titanium dioxide (TiO 2 ) is one of the most widely investigated electrode materials, owing to its low cost, abundant availability and convenient synthesis in nanoscale sizes.

“…The Sn underwent in situ oxidative growth on the MXene surface, and the Hf was also oxidized to coat their composite. [171] Wang et al synthesized an MXene/nickel-aluminum layered double hydroxide (MXene/LDH) with a porous structure based on this method (Figure 7a). In the atomic layer deposition method, a gas of metal elements precursors was mixed with the O 3 oxidizing agent to be deposited on the surface of the MXene film, and the boiling point of metal oxides must be in between the boiling point of the precursors and the treatment temperature.…”

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.
