Multi-branched FeO(OH) nanorods are successfully prepared using a facile one-pot solution-phase synthesis method. Their morphology and structure were characterized using field emission scanning electron microscopy (FE-SEM), X-ray powder diffraction (XRD), and Fourier transform infrared (FTIR) absorption spectrum. The results show amount of surfactant (PEO)20(PPO)70(PEO)20 (P123) and precipitant hexamethylenetetramine (HMTA) have significant effect on the shape of the particles. When 20-25 g of the P123 alcohol solution (20 wt%) is added the reaction solution containing 5.0 mL HMTA (2 mol/L) or when 18 g of the P123 alcohol solution (20 wt%) is added the reaction solution containing 10.0 mL HMTA (2 mol/L), the multi-branched FeO(OH) nanorods can be obtained. While when 19-22 g of the P123 alcohol solution (20 wt%) is added the reaction solution containing 10.0 mL HMTA (2 mol/L), the products became the Fe3O4 nanosheets with irregular shape. A possible growth mechanism of the multi-branched FeO(OH) nanorods is suggested.

Conventional solution-phase synthesis of azo compounds is complicated by the need for precise pH and temperature control, high concentrations of pH control reagents, and by-product removal. The microdroplet synthesis method has solved these problems.

The uniform hierarchical and microspheric copper oxide (CuO) nanostructures, which have been successfully prepared via a simple one-pot method. The detailed morphology and structure of the synthesized hierarchical and microspheric nanostructures were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) and UVvisible spectroscopy. The morphology of CuO particles depends on the ammonium dihydrogen phosphate (ADP) used in the synthesis, the formation mechanisms were proposed based on the experimental results. The catalytic activity of as-synthesized CuO was demonstrated by catalytic oxidation of methylene blue in the presence of hydrogen peroxide (H2O2) and CuO with hierarchical nanostructures was found to be the best catalyst.
