Abstract
Recently, MXene has become a prominent material and has made immense advancements in its synthesis, properties, and applications in energy storage, catalysts, sensors, and more. MXene is a group of 2D transition metal carbides/nitrides/carbonitrides with outstanding electronic and mechanical properties that arise from its unique surface chemistry. There is a vast range of unexplored MXene compositions and structures, highlighting the need to employ multiple advanced characterisation techniques within a single study. This research focuses on titanium carbide (Ti3C2) MXene derived from its precursor MAX phase, titanium aluminium carbide (Ti3AlC2), synthesized with in situ hydrofluoric acid generated from the mixture of ammonium fluoride (NH4F) and hydrochloric acid (HCl). The impact of the morphology, composition, and chemical and physical properties using this method were thoroughly investigated. The MXene was tested and characterized by field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), and Brunauer-Emmett-Teller (BET) to investigate the impact of the synthesis method on MXene, to confirm the successful synthesis of MXene, and to determine their structure, composition, and properties. This study offers an in-depth investigation and characterisation of Ti3C2, along with other etching approaches.
