Their anisotropic van der Waals (vdW) bonding nature enables them to commonly possess two-dimensional (2D) structures which have been rigorously investigated recently. Nonetheless, TMD crystals in quasi zero-dimensional (0D) forms,i.e., TMD fullerenes, have not been explored in depth from the perspective of reproducible synthesis and process-structure correlation. Herein, we report a controlled synthesis of inorganic fullerene platinum diselenide (PtSe2)viaa thermal selenization of Pt nanostructured precursors. We identified a conversion of Pt nanocubes to PtSe2"onion-like" fullerenes, dictated by a well-defined isotropic volume expansion. Extensive transmission electron microscopy (TEM) inspections revealed that there exists a certain size-dependency which leads to the preferable growth of PtSe(2)fullerenes over 2D PtSe(2)platelets. The underlying principle for this size-dependent growth is discussed in the context of surface energy minimization. Furthermore, the PtSe(2)fullerenes were verified to possess a large degree of unsaturated dangling bonds as well as internal strain, verified by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) as well as a geometric phase analysis (GPA). This study sheds light on synthesizing a wide range of TMD-based fullerenes which will foster the discovery of novel physical and chemical properties in quasi 0D material systems.
