Effects of Plasma Treatment on the Surface and Photocatalytic Properties of Nanostructured SnO-SiO Films.

In this work, we study the effects of treating nanostructured SnO-SiO films derived by a sol-gel method with nitrogen and oxygen plasma. The structural and chemical properties of the films are closely investigated. To quantify surface site activity in the films following treatment, we employed a photocatalytic UV degradation test with brilliant green.
