Boron phosphate (BPO4) is a well known catalyst for a range of organic chemical reactions. In this paper, we report the preparations and characterizations of nano-sized BPO4 and nano-BPO4-based core-shell spheres. The samples were synthesized hydrothermally using H3BO3, H3PO4 and short chain n-alkylamines (n = 3, 4) as starting materials. The resulting products were characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scan electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. A possible mechanism for the formation of the materials is also discussed.
