General Synthesis

The hierarchical porous TiO2hollow spheres were successfully prepared by using the hydrothermally synthesized colloidal carbon spheres as templates and tetrabutyl titanate as inorganic precursors. The diameter and wall thickness of hollow TiO2spheres were determined by the hard templates and concentration of tetrabutyl titanate. The particle size, dispersity, homogeneity, and surface state of the carbon spheres can be easily controlled by adjusting the hydrothermal conditions and adding certain amount of the surfactants. The prepared hollow spheres possessed the perfect spherical shape, monodispersity, and hierarchically pore structures, and the further experiment verified that the present approach can be used to prepare other metal oxide hollow spheres, which could be used as catalysis, fuel cells, lithium-air battery, gas sensor, and so on.

One Step

3D uniform Bi2S3 chrysanthemum-like microspheres with 1D nanowire-assembly were prepared through a facile one-step hydrothermal route, using poly(vinylpyrrolidone) (PVP) as a soft template, and Bi(NO3)3 and thiourea as Bi and S sources, respectively. PVP molecules played an important role in the formation of uniform 3D Bi2S3 nanostructures. The reasonable formation mechanism of uniform chrysanthemum-shaped Bi2S3 microspheres was also proposed. Photovoltaic properties were studied preliminarily to demonstrate potential application in dye-sensitised solar cells for the replacement of scarce platinum as counter electrode.
