Recent Developments in Titanium Carbide (Ti3C2)-Based Layered Double Hydroxide (LDH) Nanocomposites for Energy Storage and Conversion Applications: A Minireview and Perspectives

Abstract

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.
