“…Figure 4(a) depicts the absorbance changes of methyl orange under different degradation times, where 1-cm 2 Cu2O/Al2O3 sheet was used as the photocatalyst, the concentration of methyl orange solution was 5 mg/L and the volume of H2O2 solution was 2 ml. As is clear, the absorbance of methyl orange decreased with the extension of degradation time, indicating increase in the degradation rate of methyl orange [9]. According to the absorbance values of methyl orange at different catalytic times, it could be degraded into low-molecular-weight organic matter by the action of TiO2/Al2O3.…”

To efficiently degrade printing and dyeing wastewater at low costs, Cu2O/Al2O3 catalyst was prepared by electrochemical method. Under its combined action with H2O2, photocatalytic degradation of methyl orange solution, as simulated wastewater, was carried out. With the aid of X-ray diffractometer, X-ray microanalysis system and scanning electron microscope, the structure and composition of catalyst film were designed by adjusting the electrochemical parameters, and the performance of photocatalyst was evaluated by the degradation rate of methyl orange. It was found that after anodizing aluminum alloy for 2 h in a 2 mol/L H2SO4 solution under a voltage of 15 V, alumina film with reasonable pore size distribution could be prepared on the alloy surface. By electroplating the film in a 0.01 mol/L CuSO4 solution at 5°C, and then hydrothermally treating it at 200°C, the Cu2O/Al2O3 photocatalyst could be obtained. The prepared Cu2O/Al2O3 and 10% H2O2 were used jointly as photocatalyst to degrade 10 mg/L methyl orange solution for 480 min, which achieved a methyl orange degradation rate of up to 82.1%.

The electronic, optical, magnetic, and thermoelectrical properties of both, the monoclinic (α-form) and the orthorhombic (β-form) phases of sodium manganese (II) arsenate NaMnAsO 4 cluster are investigated comprehensively by the first-principle calculations based on the Density Functional Theory. The fullpotential linearized augmented plane waves method within the generalized gradient approximation (GGA) and GGA + U approaches have been performed by the Wien2k software. Thermodynamic stability is confirmed by means of formation energy (ΔH f ). The spin-polarization is included in the calculations to study the electronic and magnetic properties. The indirect bandgaps are observed for the monoclinic phase, then the direct bandgaps are reported at Γ-symmetry point for the orthorhombic phase. The density of state, besides the band structure calculation, revealed that the studied material can be identified as a ferromagnetic semiconductor at low temperature with an optical bandgap energy of 1.35 and 0.83 eV for monoclinic and orthorhombic phases with GGA approach, as well as 1.27 and 1.59 eV with GGA + U approach, respectively. The refractive index range is 1.5 to 2.4 along with a wide absorption band in the UV region, which makes this material outstanding for optoelectronic devices. The thermoelectric properties for both structures have also been investigated using the BoltzTraP package. The obtained electrical conductivity, as well as the figure of merit, are found to be important for thermoelectrical devices. This suggests that NaMnAsO 4 could pave the way to further experimental research on optoelectronicthermoelectric applications.
