As a result of the rapid industrial development and increase of world population, energy and the environment have become the major issues that demand urgent attention. Introducing new materials with layered textures, low cost, and high surface areas could provide attractive strategies to overcome the challenges for sustainable development. In this perspective, titanium carbide (Ti3C2) MXenes and layered double hydroxides (LDHs) are extraordinary nanomaterials due their two-dimensional (2D) structures and excellent properties. Such materials offer the advantages of large surface area and excellent conducting properties. The Ti3C2 MXenes have outstanding 2D structure with outstanding electronic conductivity, whereas LDH has strong adsorption and semiconducting properties. Coupling them would be promising to form a good composite with higher efficiency. The main objectives of this work to investigate the recent development in Ti3C2-based LDH nanocomposites for energy storage and conversion applications. In this article firstly the synthesis techniques adopted for LDH, Ti3C2MXene and LDH/Ti3C2 MXeneare summarized whereas the optical and structural properties involved to obtain highly effecient materials are are also discussed. The advancements to obtain highly efficient hybridized material of LDH and TiC MXene for energy storage, hydrogen production, and carbon dioxide reduction have been systematically explained. Finally, the challenges and perspectives toward the future research of MXene-based LDH composites have been disclosed.

A well-designed two-dimensional 2D/2D architecture was constructed by coupling oxygen-vacancy-rich trimetallic CoAlLa layered double hydroxide (CoAlLa-LDH) with titania-sandwiched Ti 3 C 2 MXene multilayers to achieve enhanced photocatalytic CO 2 reduction. First, through a controlled etching process, in situ anatase/rutile-phase titania was grown over Ti 3 C 2 multilayers with a controlled morphology. In the next stage, through controlled growth, a highly active oxygen-vacancy-rich ternary CoAlLa-LDH was formed in the presence of La 3+ to create coordinatively unsaturated metal centers for enhancement of reductive sites. An intimate contact between the trimetallic CoAlLa layered double hydroxide (CoAlLa-LDH) and Ti 3 C 2 T x with a unique 2D/2D hierarchical architecture was achieved. This step (S)-scheme heterojunction provided pathways to effectively stimulate the photoinduced electron−hole separation. Compared to bimetallic Co 2 Al 1 -LDH, higher photoactivity was achieved with trimetallic Co 2 Al 0.95 LA 0.05 -LDH due to the presence of electron-rich La 3+ . The photocatalytic reduction of CO 2 with H 2 O resulted in the formation of CO and CH 4 with yield rates of 46.32 and 31.02 μmol g −1 h −1 , respectively, over the Co 2 Al 0.95 LA 0.05 -LDH/TiO 2 /Ti 3 C 2 MXene nanocomposite, much higher than pristine samples. This significantly enhanced performance was due to the better sorption process with superior charge carrier separation due to oxygen defective sites, good interfacial contact, and the presence of dual-phase titania as a bridge for separating charges. The composite performance was further explored through photocatalytic dry reforming of methane (DRM) and bireforming of methane (BRM), whereas higher CO and H 2 production was obtained for BRM due to the effective attachment of reactants over electron-rich defective sites. Additionally, the quantum efficiency and stability study confirmed the high durability of the Ti 3 C 2 T/CoAlLa-LDH composite catalyst in several cycles owing to the stable structures of Ti 3 C 2 T A/R with basic characteristics of CoAlLa-LDH.

“…Being pseudocapacitive layered materials, MXenes have demonstrated higher capacitance than carbon-based materials. [710][711][712][713][714][715][716][717][718][719][720] Lukatskaya et al 721 reported that Ti 3 C 2 T x MXene lms possessed a C sp of 210 F g À1 at the scan rate of 10 V s À1 , which was higher than the capacitance achieved with carbonbased SC electrodes. The multi-layered MXene was synthesized by the etching of Ti 3 AlC 2 with HCl/LiF solution.…”
