文摘

Based on the “polymer-cation templates” technique, well-defined BaMoO₄ hollow spheres with an average diameter of 2.3 μm have been synthesized via a simple precipitation reaction between BaCl₂ and (NH₄)₆Mo₇O₂₄ · 4H₂O at room temperature in the presence of poly(methacrylic acid). The size of the hollow spheres could be tuned down to 1.5 μm by decreasing the concentrations of Ba2+ or MoO₄2? ions in the reaction solution. Compared with current fabrication routines for hollow spheres, this method is facile and cost-effective as no surfactant is needed, and can be applied to produce other inorganic hollow-structured materials.
