摘要SnO2 is prepared by the hydrolysis and the automatic oxidation of SnCl2 in water, it shows the photo catalytic activity for the degradation of methyl orange in water under the UV light illumination. In the above process, methyl orange concentration decreases quickly, the total organic carbon (TOC) decreases slowly; inorganic ions (SO42-, NO3-, NH4+) can be formed; the pH value in the system decreases gradually; a small quantity of HO center dot can be generated. In order to estimate the roles of active species during the above process, isopropanol, ammonium oxalate, and 1,4-benzoquinone, as the scavengers for HO center dot, h(+), O-2(-) are introduced into the systems respectively. Isopropanol and (NH4)(2)C2O4 are effective scavengers for active species HO and h(+) respectively; but 1,4-benzoquinone is not a satisfactory scavenger to capture O-2(-) at least in this work. At last, SnO2 is characterized by N-2 sorption, DRS, XRD, SEM and TEM. (C) 2016 Elsevier B.V. All rights reserved.
