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

Mesoporous single crystal-like YOnanocubes have been prepared through a coordination-based selfassembly process.Firstly,a uniform nanocube-Iike 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.Nadsorption-desorption demonstrates the mesoporous characteristics of the YOnanocubes,showing a relatively high surface area of 60 m~2/g.
