Hollow nanostructures have great potentials in the current and emerging areas of nanotechnology. Structural features of the hollow nanostructured materials such as high surface area and large void space gain broad interests as drug containers, advanced electrodes, and nanoreactors. A wide variety of soft-templating methods have been employed to prepare inorganic hollow nanospheres.  Here, we report the single micelle template method to synthesize the sub-50 nm hollow nanospheres of nickel phosphate (NiP). The advantage of this method is that the chemically distinct three blocks of triblock copolymer contribute to the fabrication of hollow nanospheres. Phosphate ion is a bridge between PVP and Ni<sup>2+</sup> ion. The removal of polymer template form the hollow spheres of NiP with the amorphous shell. The hollow nanospheres of nickel phosphate with amorphous shell shows the promising application in reduction of p-nitrophenol
