Degradation Of Methyl Orange

Six benzimidazole derivatives were synthesized and charactrized by IR spectra, 1H-NMR spectra and MS spectra. The coordination reaction of the derivatives with CuCl2. And six novel Cu (II) complexes with the derivatives were prepared and characterized by UV spectra, IR spectra and elemental analysis. The catalytic degradation of methyl orange aqueous solution was investigated using the complexes as catalysis in presence H2O2 by HPLC method and Vis-spectrophotometry. The result of characterization showed that there are four coordination sites around Cu (II) in all complexes, which are respectively occupied by one sulfur atom (from the derivative), one nitrogen atom (from the derivative), one oxygen atom ( from the OH-) and one chlor atom (from the Cl-). The degradation of methyl orange indicated that all the complexes show the properties of enzyme activity. And the main degradation products determined were hydroquinone and maleic acid.

First Time

SnSe2/Se heterojunction films were successfully grown on fluorine-doped tin oxide (FTO) glass for the first time via a one-step solvothermal route using magnetron sputtered Sn metallic precursors, Se powders as selenium source, cyclohexanol as solvent and cyclohexanol as auxiliary solvent, respectively. The SnSe2/Se heterojunction films consisted of Se nanoparticles or nanorods cluster and SnSe2 network surface layers. The crystalline phase and morphology of SnSe2/Se films were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), respectively. The photocatalysis measurements of the products for rhodamine Blue (RhB) demonstrated that SnSe2/Se heterojunction films revealed better dye degradation properties than SnSe2 nanosheet films due to the higher separation rates of photogenerated electron–hole pairs of SnSe2/Se heterojunction films, which can be confirmed by surface transient photovoltage (TPV) analyzer.
