In-situ continuous hydrothermal synthesis of TiO2 nanoparticles on conductive N-doped MXene nanosheets for binder-free Li-ion battery anodes

Ti3C2‐MXene Partially Derived Hierarchical 1D/2D TiO2/Ti3C2 Heterostructure Electrode for High‐Performance Capacitive Deionization

“…[30] After alkali treatment, the Ti-X peak at 455.5 eV disappeared, with a decrease in Ti-C peak intensity and an increase in Ti(IV) peak intensity (Figure 2c), indicating that TiO 2 was generated by the partial destruction of Ti 3 C 2 . [31] The N 2 adsorption-desorption isotherms of the TiO 2 /Ti 3 C 2 hybrids displayed a representative type-IV curve with an H3-type hysteresis loop (Figure 2d), indicating the predominant mesoporous structures of the compounds and showing a slit pore geometry due to the stacking of spark particles. [32] The SSA of TiO 2 /Ti 3 C 2 (50.74 m 2 g −1 ) was much larger than that of the pristine MXene nanosheets (S BET = 17.56 m 2 g −1 ) due to the growth of TiO 2 nanowires on the interlayer increasing the interlayer space of Ti 3 C 2 .…”

Element‐Doped Mxenes: Mechanism, Synthesis, and Applications

“…Ti 3 C 2 T x nanosheets with high electrical conductivity can serve as a 3D framework to form a solid mechanical support to strengthen the integrity of the hybrid structure for enhanced charge transfer. [255][256][257][258] At the same time, it provides abundant active sites, suppresses the loss of S during charge and discharge, and improves the cycle stability of the anode material. [140] However, the transport kinetics of Na ions within the MXenes interlayer remains challenging due to the large atomic radius of Na ions.…”

MXene in core–shell structures: research progress and future prospects

“…7 The blooming research opportunity in developing MXenes not only sought their probable hybrid combinations, 8,9 but also aided better functionalities, understanding of their properties, and further evaluations toward suitable applications. 10,11 For instance, MXenes have attracted tremendous interest for use in energy storage systems 12,13 which have been traditionally explored by using metal-based, 14 carbon-based, 15 polymer-based, 16 and hybrid metal/carbon/polymer-based materials. 17,18 Scientic studies of electrode materials such as carbon nanotubes, graphene oxide (GO), metal chalcogenides, metalorganic frameworks (MOFs), metal phosphides, high-entropy alloys, and layered hydroxides, and their progress in transiting towards hybrid materials and oriented structures have been signicant and well investigated throughout the years.…”
