ln io3 3 ln ce nd eu gd er yb polycrystals as novel photocatalysts for efficient decontamination under ultraviolet light irradiation
Inorganic Chemistry, 2014Co-Authors: Wenjun Wang, Hefeng Cheng, Baibiao Huang, Xiaoyan Qin, Xiaoyang Zhang, Ying DaiAbstract:Ln(IO3)3 (Ln = Ce, Nd, Eu, Gd, Er, Yb) polycrystals were hydrothermally synthesized using lanthanide nitrate or lanthanide oxide and Iodic Acid as precursors. X-ray diffraction was used to characterize the crystal structures of the Ln(IO3)3 products. Scanning electron microscopy was carried out to observe the microscopic morphologies. The lattice spacings were studied by high-resolution transmission electron microscopy and selected area electron diffraction. We evaluated the photocatalytic efficiency by decomposing methyl orange dye under ultraviolet light irradiation, and the Ln(IO3)3 products show excellent photocatalytic properties. To rule out the effect of photosensitization, 2,4-dichlorophenol was also photodegraded. As one of the key factors of photocatalysis, ultraviolet–visible diffuse reflectance spectra of the Ln(IO3)3 samples were also studied, and all products have strong absorption in the ultraviolet region.

pure gold dissolution in dilute chloric bromic or Iodic Acid solution containing abundant halide ions
Journal of Molecular Liquids, 2017Co-Authors: Masashi Hojo, Masahiko Yamamoto, Tetsuya Maeda, Hiroki Kawano, Kei OkamuraAbstract:Abstract The pure gold dissolution has been explored in (dilute) chloric, bromic, or Iodic Acid (HXO3, X = Cl, Br, I) aqueous solution containing abundant halide ions at 60 °C. It has been found that mixtures between sodium chlorate and HCl (NaClO3 + HCl ⇆ HClO3 + NaCl) in 20 mL are effective media for the dissolution of pure gold-wire (99.95 %, ca. 20 mg, 0.25 mm diameter). The gold-wire dissolution is much more enhanced by HBr than HCl in NaClO3 solution. At 0.50 mol dm-3 NaClO3, for instance, log (k/s-1) values are -5.11 and -3.40 (ca. 50-fold increase) for 1.0 mol dm-3 HCl and HBr, respectively, where “pseudo” first-order dissolution rate constants (k/s-1) have been evaluated by the changes in the mass of gold-wire. In HClO3 solution containing abundant halide ions (X- = Cl-, Br-), the Au metal should be oxidized mainly by X2 to be AuX4-, where X2 is produced by the oxidizing power from HClO3, just as dilute HNO3 ( ~ 5 mol dm-3).

The gold-wire dissolution is much more enhanced by HBr than HCl in NaClO 3 solution. At 0.50 mol dm -3 NaClO 3 , for instance, log ( k /s -1 ) values are -5.11 and -3.40 ( ca. 50-fold increase) for 1.0 mol dm -3 HCl and HBr, respectively, where “pseudo” first-order dissolution rate constants ( k /s -1 ) have been evaluated by the changes in the mass of gold-wire. In HClO 3 solution containing abundant halide ions (X - = Cl - , Br - ), the Au metal should be oxidized mainly by X 2 to be AuX 4 - , where X 2 is produced by the oxidizing power from HClO 3 , just as dilute HNO 3 ( -3 ) containing abundant NaCl. In NaBrO 3 solution, however, HBr does not acquire any superiority to HCl in the gold dissolution. In NaIO 3 solution, the effect of HX at the lower concentrations ( -3 ) of NaIO 3 increases in the order of HCl 3 - or NO 3 - ) from a strong Acid (HClO 3 or HNO 3 ) is subject to be protonated in the “aqueous solution” modified by electrolytes of very high concentrations (> ~ 5 mol dm -3 ).
