“…The most important plane, (1 1 1), corresponding to the titanium carbide structure in its face-centered cubic (FCC) crystalline phase [24], was identified in Figure 5(b). Additionally, the (0 0 2) plane, corresponding to graphite planes, was identified in Figure 5(d) [25]. However, no atomic planes were observed in the shell structure proposed as the carbon This observation confirms the possibility of proposing the production of Ti-C core-shell or even TiC-C nanostructures.…”

This paper reports on the ablation process of a pure Ti solid target immersed in a C-enriched acetone solution, leading to the production of titanium carbide (TiC) and Ti-C core-shell nanostructures. The used route of synthesis is generally called pulsed laser ablation in liquid (PLAL). The presence of carbon structures in the solution contributed to the carbon content in the produced Ti-based nanomaterials. The atomic composition of the produced nanostructures was analyzed using SEM-EDS, while TEM micrographs revealed the formation of spherical TiC and core-shell nanostructures ranging from 40 to 100 nm. The identification of atomic planes by HRTEM confirmed a 10 nm diameter C-shell with a graphite structure surrounding the Ti-core. Raman spectroscopy allowed for the identification of D and G peaks for graphite and a Raman signal at 380 and 600 cm −1 , assigned to TiC. The results contribute to the state-of-the-art production of TiC and Ti-C core-shell nanostructures using the PLAL route.
