An interesting morphology-evolution of Cu2O from cubic, edgetruncated cubic, edge- and corner-truncated octahedral, truncated octahedral, and finally to octahedral architectures was readily achieved by adjusting the concentration of hydroxyl. When evaluated for their photocatalytic performances, these polyhedral Cu2O crystals manifest shape-dependent properties.

We have demonstrated a facile anion-assisted strategy for the synthesis of nanoparticle-aggregated CuO nanoellipsoids. Structural and morphological evolutions were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), andfield-emission scanning electron microscopy (FESEM). The nanoparticle-aggregated CuO nanoellipsoids serve as a promising electrode material for a non-enzymatic glucose biosensor which shows high sensitivity, good reproducibility, a fast amperometric response and good selectivity. The study is of great importance in the bottom-up assembly of tunable ordered architectures, and offers a chance to understand the formation mechanism and fundamental significance of an anion-assisted strategy for the synthesis of metal oxides. Significantly, it is believed that the anion-assisted synthetic approach reported
here could provide a facile way to design more novel metal oxide architectures with well-defined shapes.

In this report, a novel type of a hollow CuO polyhedron-modified electrode for sensitive nonenzymatic glucose detection has been fabricated by a templating approach. The morphologies and structures were characterized by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectrum and X-ray photoelectron spectroscopy (XPS). These results show that the as-prepared hollow CuO consists of numerous CuO nanoplates. The electrochemical performance for glucose detection was investigated by cyclic voltammetry and chronoamperometry. The hollow CuO polyhedron-modified electrode exhibits a high sensitivity of 1112 μA mM-1 cm-2 with a detection limit of 0.33 mM (S/N = 3) at +0.55 V, and the linear range is up to 4 mM. Moreover, the hollow CuO polyhedron-modified electrode is highly resistant to the interference from interfering species such as sodium chloride (NaCl), ascorbic acid (AA) and uric acid (UA). The hollow CuO polyhedron-modified electrode exhibits high sensitivity, low detection limit, good stability and fast response towards the oxidation of glucose; thus, it may be a promising nonenzymatic glucose sensor.

    We have demonstrated the significant evidence on a green synthesis for the ordered-aggregation-driven growth from surfactant-free one-dimensional (1D) CuO nanosubunits into dimension-controlled mesostructures (three-dimensional (3D) mesospindles and two-dimensional (2D) mesoplates) by an additive-free complex–precursor solution route. Structural and morphological evolutions were investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) and field-emission scanning electron microscopy (FESEM). The formation of CuO mesostructures here is essentially determined by the characteristic of [Cu(OH)4]22 precursors, and an oriented nanoparticle aggregation with tailoring shapes in different dimensions can be achieved in different concentration of reactants at higher reaction temperature. The 3D "layer-by-layer" growth of mesostructural CuO spindles is successfully synthesized in low concentrations of reagents, while the 2D ‘‘shoulder-by-shoulder’’ growth of mesostructural CuO plates is obtained in high concentrations of reagents. The study is of great importance in the bottom-up assembly of controllable ordering architectures, and offers a good opportunity to understand the fundamental significance for the investigation of the formation mechanism and growth process of surfactant-free CuO mesostructures with controllable aggregation-based behaviours. Additionally, we further demonstrated that such CuO mesocrystals could serve as a potential photocatalyst for the degradation of rhodamine B (RhB) under visible light irradiation in the presence of hydroxide water (H2O2). The results also suggest that these 3D mesostructural CuO spindles exhibit a higher adsorption and photocatalytic degradation of RhB than that of 2D mesostructural CuO plates.
