“…[3][4][5][6][7] Among them, porous copper (II) oxide, as an important p-type semiconductor with a narrow bandgap(1·2 eV), has attracted much attention due to its low cost, high stability and non-toxicity. 8 To date, porous copper (II) oxide micro-/nanospheres, nanowires, nanosheets, nanobelts, nanospindles, microrods, hollow octahedra and hexapod nanostructures have been prepared and displayed outstanding properties. [9][10][11][12][13][14][15][16] In the authors' previous work, porous copper (II) oxide microspheres were prepared by the solvothermal method, which showed a good response sensitivity and low detection concentration for ethanol.…”

Porous manganese (Mn)-doped copper (II) oxide (CuO) microplates were synthesized by a facile hydrothermal method. The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller N 2 adsorption-desorption analysis and Fourier transform infrared spectroscopy. It is shown that the morphologies of samples can be transformed from hierarchical porous microspheres to microplates by doping with manganese ions. The manganese-doped copper (II) oxide (10%) has a wide pore size distribution from micropore to macropore, and its surface area is 16·82 m 2 /g, which is 2·4 times that of copper (II) oxide microspheres (6·92 m 2 /g). It shows excellent adsorption properties for potassium ethyl xanthate. The saturated adsorption capacity of porous manganese-doped copper (II) oxide (10%) microplates for potassium ethyl xanthate is 5219 mg/g, which is 6·4 times that of copper (II) oxide microspheres (813 mg/g). The excellent adsorption property is mainly attributed to the intrinsic structure and the large specific surface area. This approach is expected to be extended to the preparation of other porous materials.Langmuir constrants m mass of the sample (g) q e adsorption capacity (mg/g) V volume of solution

“…There are several semiconductor nanostructures like CuO, Fe 2 O 3 , ZnO, ZnS, CuS, Nb 2 O 5 and TiO 2 have been developed for the photocatalytic degradation of various organic pollutants [21][22][23][24][25][26][27]. Among these semiconductors, CuO nanostructure is a potential candidate for the catalytic activities due to its higher surface area and ease tuning of size and shape [28]. Methyl orange (MO) is an important coloured compound being used in dyeing and textile industries, which causes toxic to the human health.…”

A controlled synthesis of CuO nanostructures with various morphologies were successfully achieved by presence/absence of low frequency (42 kHz) ultrasound with two different methods. The size, shape and morphology of the CuO nanostructures were tailored by altering the ultrasound, mode of addition and solvent medium. The crystalline structure and molecular vibrational modes of the prepared nanostructures were analysed through X-ray diffraction and FTIR measurement, respectively which confirmed that the nanostructures were phase pure high-quality CuO with monoclinic crystal structure. The morphological evaluation and elemental composition analysis were done using TEM and EDS attached with SEM, respectively. Furthermore, we demonstrated that the prepared CuO nanostructures could be served as an effective photocatalyst towards the degradation of methyl orange (MO) under visible light irradiation. Among the various nanostructures, the spherical shape CuO nanostructures were found to have the better catalytic activities towards MO dye degradation. The catalytic degradation performance of MO in the presence of CuO nanostructures showed the following order: spherical \ nanorod \ layered oval \ nanoleaf \ triangular \ shuttles structures. The influence of loading and reusability of catalyst revealed that the efficiency of visible light assisted degradation of MO was effectively enhanced and more than 95 % of degradation was achieved after 3 cycles.

“…Therefore, in order to improve the TiO 2 and ZnO catalyst and to develop a visible light catalyst, great efforts have been made to couple them with narrow band gap metal oxides that can be irradiated by visible light intrinsically. CuO is a metal oxide material with a narrow band gap (1.2 08 eV) and is known to be an efficient catalyst for gas phase reactions [5]. Several studies have shown that in the absence of H 2 O 2 , CuO exhibited a lower catalytic activity [6][7].…”
