## Description

- description: STEM and XPS analyses were combined to clarify the ultraviolet light-induced
    surface changes of WO3 in air. IL-STEM analysis showed that the WO3 particle surface
    was covered with an amorphous thin film after ultraviolet irradiation in air.
    XPS analysis showed that hydrocarbon decomposition and formation of carboxyl/hydroxyl
    species occurred. These results suggested that the amorphous thin films would
    consist of photocatalytic oxidative species of hydrocarbon. IL-STEM analysis could
    detect small light-induced changes. This technique will be useful for microscopic
    characterization of photocatalysis or photoinduced hydrophilic conversion.
