Facile synthesis of coordination polymer nanocubes and their conversion into mesoporous single crystal-like Y2O3 nanocubes

Mesoporous single crystal-like Y2O3 nanocubes have been prepared through a coordination-based self-assembly process. Firstly, a uniform nanocube-like Y-lysine precursor was simply prepared with hydrothermal treatment. After the simple thermal treatment process, nanocube-shaped yttrium oxides with the morphology inherited from the Y-lysine precursor were successfully prepared. The phase, morphology, size and crystalline structure were well characterized by XRD, SEM and TEM. N2 adsorption–desorption demonstrates the mesoporous characteristics of the Y2O3 nanocubes, showing a relatively high surface area of 60 m2/g.
