Large quantities of zinc sulphide hierarchical hollow spheres were successfully obtained by a mild organic acid-assisted route using zinc chloride anhydrous and thiourea as precursors. Malonic acid played a key role as a structure-directing agent in driving such hierarchical hollow spheres structures. Certain amounts of malonic acid are necessary in formation of zinc sulphide hierarchical hollow spheres. The photocatalytic properties of as-synthesised zinc sulphide hierarchical hollow spheres have been studied, which shows an excellent photocatalytic activity for the degradation of rhodamine B under ultra-violet.

    ABSTRACT: Hierarchical SnIn4S8 microspheres were successfully fabricated via a solvothermal method without the assistance of any templates or surfactants. These microspheres were of a new tetragonal polymorph, distinct from the cubic counterpart popularly reported in the literature. Systematic characterization indicated that these microspheres exhibited a diameter of 2–4 μm and were assembled by numerous interconnected nanosheets of 40 nm thickness. The formation mechanism of hierarchical SnIn4S8 microspheres was proposed by taking into account the influences of experimental conditions on the morphology and structure. Hierarchical microspheres possessed a large specific surface area of 197 m2 g−1 and an accessible porous configuration, which gave rise to an excellent visible light-driven photocatalytic efficiency for methyl orange degradation in aqueous solutions, superior to that for the known N-doped TiO2 photocatalyst.

    ABSTRACT: Nano-sized GdPO<sub>4</sub>:Eu<sup>3+</sup> hierarchical hollow spheres were successfully synthesised through chemical conversion using Gd(OH)CO<sub>3</sub>:Eu<sup>3+</sup> nanospheres as templates. The obtained hollow spheres were composed of primary nanowires. Based on the time-dependent experiments, the hollow shells were proposed to be formed through chemical conversion from the precursor spheres. The as-prepared GdPO<sub>4</sub>:Eu<sup>3+</sup> hollow spheres exhibit good photoluminescence performance. Furthermore, the current method can serve as a general way for the synthesis of rare-earth phosphates hollow spheres.

    ABSTRACT: In this work, we present a facile template-free precipitation method for the large-scale preparation of hierarchical WO3 core–shell microspheres in which the core was composed of aggregated nanoparticles encapsulated by a hierarchical shell layer self-assembled by ultrafine nanoplates with a thickness of about 15nm. The products are characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), differential scanning calorimetry and thermogravimetry (TG/DSC). The experimental parameters affecting the morphology were discussed in detail. We found that the concentration of citric acid and pH value of the reaction solution had profound effects on the morphology of the products. In addition, a formation mechanism was proposed for producing hierarchical WO3 core–shell microspheres. Furthermore, the obtained hierarchical WO3 core–shell microspheres showed superior photocatalytic activities for the degradation of rhodamine B (RhB) under visible light irradiation.
