摘要：

Novel beta-MoO3 and WO3 hollow nanospheres were synthesized using a soft template of polymeric micelle with core-shell-corona architecture. Poly(styrene-b-[3-(methacryloylamino)propyl] trimethylammonium chloride-b-ethylene oxide) micelles (PS-PMAPTAC-PEO) with cationic shell block effectively produce core/ shell composite particles through electrostatic interaction with anionic precursors WO42- and MoO42- Transmission electron microscope (TEM) images of beta-MoO3 and WO3 have confirmed the hollow structure with average outer diameter of 42 +/- 2 and 46 +/- 2 nm, respectively; the hollow cavity diameters were found to be 16 +/- 1 nm and 14 +/- 1 nm for beta-MoO3 and WO3, respectively. The combination of nitrogen adsorption/desorption analyses and TEM observation confirmed the presence of disordered mesopores in the shell domain of beta-MoO3 and WO3 hollow particles.
