Synthesis of CuO nanosheets via hydrothermal method

In this paper, CuO nanosheets were successfully synthesized by a simple hydrothermal method. The synthesized CuO nanosheets were characterized by powder X-ray diffraction (XRD) scanning electron microscopy (SEM) Fourier Transform Infrared (FTIR) surface area analysis (BET). Several factors influencing the synthesis of material such as concentration of NaOH, hydrothermal temperature and hydrothermal time were studied. Scanning electron microscopy (SEM) investigation reveals that CuO nanosheets have the length of about 500 - 1000 nm. N2 adsorption–desorption isotherm experiment shows that the BET specific surface area of obtained CuO nanosheets is 12.78 m2/g.

Preparation and Characterization of MnO<sub>2</sub> Loaded CuO Nanosheets

CuO nanosheets in rectangle shape with widths around 90 nm and lengths about 180 nm were prepared via a hydrothermal route in the presence of CTAB. MnO2 nanoparticles with diameters around 10nm were loaded onto the surface of CuO nanosheets via an immersion approach followed by a calcination process. X-ray diffraction (XRD), Transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) were applied for the characterization of the as-prepared MnO2 loaded CuO nanosheets. It was found that CTAB played a crucial role in the morphology-controlled synthesis of CuO nanosheets. The hindrance effect resulted from the preferred adsorption of CTAB on certain facets leading to the formation of CuO nanosheets. MnO2 loaded CuO nanosheets can be expected to be a promising catalyst for the heterogeneous catalytic ozonation due to its composite phases, high dispersity, and large specific surface area.
