摘要：

We report a facile route using precipitation reaction and sequential calcination to synthesize three-dimensional (3D) Flower-like magnesium borate (Mg3B2O6) nanoarchitectures with poly(vinyl pyrrolidone) (PVP) as the template. The structure and morphology were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM). The results indicate that 3D Flower-like Mg3B2O6 microspheres with diameters of 0.6-1.0 mu m are composed of large numbers of single crystalline nanosheets with thickness of about 10 nm. The N-2 sorption result and pore-size distribution analysis show that mesopores and macropores exist in the 3D flower-like nanostructures. The mesopores and macropores will endow the hierarchical microspheres with novel application potentials. (C) 2011 Elsevier B.V. All rights reserved.
