Controlling the morphology of carbide MAX phases/MXenes through the starting carbon source

Project description

Carbon templates for high-performance batteries

Scientists have long investigated MAX phases for their distinctive metallic and ceramic qualities, yet they often neglect how initial ingredients shape a material’s final form. Supported by the Marie Skłodowska-Curie Actions programme, the MorphoXene project will explore this by using various carbon templates, including fullerenes, nanotubes and marine sponges, to mould these materials into specific zero-, one- and three-dimensional structures. The project aims to determine whether these customised shapes can improve lithium-ion battery performance by providing shorter pathways for energy transfer. Beyond testing batteries, the project will also highlight the significance of examining material morphology alongside chemical composition. The goal is to enable the integration of these materials with enhanced structural control into a range of future functional devices.

Objective

MAX phases, a family of inorganic layered compounds with a unique combination of metallic and ceramic properties, have found interesting applications in several fields: high temperature coatings, joining, catalysis, sensing, biomedicine, solar energy harvesting, and energy storage... Although MAX phases have been known since the early 1960s, little attention has been paid to the effect that the starting reagents may have on the morphology (and, therefore, properties) of the final material. Thus, for the particular case of the syntheses of carbide-MAX phases, the key question that arises is: could the carbon source serve as a template and somehow transfer its morphological features to the resultant product? MorphoXene project aims at preparing Ti3AlC2 (MAX phase) and Ti3C2Tx (MXene) with unconventional zero-, one-, and three-dimensional (0D, 1D, and 3D, respectively) morphologies by choosing a carbon source (template) distinct from the typically used graphene powder: i) 0D (C60-Ih)[5,6]fullerene (C60), ii) 1D single-walled carbon nanotubes (SWCNTs) and iii) the 3D hierarchically porous graphitic architecture resultant from the pyrolysis of Hippospongia communis, the most common marine sponge in the Mediterranean Sea. Moreover, in virtue of their shorter diffusion paths and/or the hierarchically porous structure in contrast to conventional MXenes, the performance of 0D, 1D, and 3D Ti3C2Tx compounds as anode materials in lithium-ion batteries (LIBs) will be tested and compared with that of the state-of-the-art Ti3C2Tx MXenes. This project will enable the Researcher to acquire professional maturity in the preparation of advanced materials with tailor-made properties. Moreover, it is expected that a better control over the morphology brings MXenes closer to their integration into a plethora of functional devices. Undoubtedly, this project will increase the awareness of the scientific community on the need of exploring not only new compositions, but also morphologies.
