Effects of Plasma Treatment on the Surface and Photocatalytic Properties of Nanostructured SnO2–SiO2 Films

In this work, we study the effects of treating nanostructured SnO2–SiO2 films derived by a sol-gel method with nitrogen and oxygen plasma. The structural chemical properties are closely investigated. To quantify surface site activity in following treatment, employed photocatalytic UV degradation test brilliant green. Using X-ray photoelectron spectroscopy, it was found that treatment plasma led to high deviation stoichiometry SnO2 even appearance tin monoxide phase. These samples also exhibited maximum activity. contrast, did not lead any noticeable changes material. However, increasing power source from 250 W 500 an SnO fraction on reduction general, all types tested amorphization samples.
