  • A new strategy has been presented to the controllable synthesis of CuInS{sub 2} hollow nanospheres based on the Cu{sub 2}O solid nanospheres as the precursor in the absence of any surfactant. Specifically, the CuInS{sub 2} hollow nanospheres result from hydrothermal transformation of the intermediate Cu{sub 7}S{sub 4} hollow nanospheres derived from Cu{sub 2}O solid nanosphere precursor by the Kirkendall effect in the conversion process. The CuInS{sub 2} hollow nanospheres with diameters of about 250 nm are assembly of nanoparticles with an average size of 20-30 nm. The composition, structure, and morphology of the Cu{sub 2}O precursor, the Cu{sub 7}S{sub 4}more » intermediate, and final CuInS{sub 2} product have been, respectively, characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) with selected area electron diffraction (SAED). Different from investigation of photovoltaic properties, in this work, the as-prepared CuInS{sub 2} hollow nanospheres have been explored as anode materials for rechargeable lithium ion batteries. They deliver a large initial discharge capacity of 1144 mAh g{sup -1} and exhibit good cycle performance with a discharge capacity of 265 mAh g{sup -1} after 20 cycles, which are superior to those of CuInS{sub 2} nanoparticles. The suitable surface area and relatively stable structure of the CuInS{sub 2} hollow nanospheres play an important role in their enhanced electrochemical performance as anode materials. - Graphical abstract: CuInS{sub 2} hollow nanospheres was successfully prepared from Cu{sub 2}O solid nanospheres in the absence of any surfactant, which can deliver a large initial discharge capacity of 1144 mAh g{sup -1} and exhibit good cycle performance. Highlights: Black-Right-Pointing-Pointer CuInS{sub 2} hollow nanospheres were synthesized hydrothermally from Cu{sub 2}O nanospheres. Black-Right-Pointing-Pointer The CuInS{sub 2} hollow nanospheres present high discharge capacities as anode materials. Black-Right-Pointing-Pointer Better cycling performance can be attributed to its hollow structure.« less
  • CuO hierarchical hollow nanostructures, assembled by nanosheets, were successfully prepared in n-octanol/aqueous liquid system through a microwave approach. Controlled experiments revealed that both bubble and interface play key roles in determining the self-assembly process of CuO hierarchical hollow nanostructures, and the morphology/size of building blocks and final products could be readily tuned by adjusting reaction parameters. Furthermore, a self-assembly mechanism of aggregation-then-growth process through bubble template was proposed for the formation of the hollow hierarchical architectures. Photocatalytic performance evidenced that the obtained CuO hierarchical hollow nanostructures possessed superior photocatalytic efficiency on RhB than that of non-hollow nanostructures, which could bemore » easily demonstrated by SPS response about the separation and recombination situation of photogenerated charges. - Graphical abstract: From 2-D CuO nanosheets to 3-D hollow nanospheres: interface-assisted synthesis, surface photovoltage properties and photocatalytic activity. Various CuO architectures with different morphologies and sizes, including hierarchical hollow nanostructures were prepared through a synergic bubble-template and interface-assisted approach.« less
