Abstract
In this study, the application of recovered metals from spent batteries by extraction was investigated for ozone decomposition as a catalyst. Among the recovered metals, Mn contents was the most important factor for ozone decomposition. It was also found that the deactivation rate of the catalyst was dependent on the Zn contents, while K contents and activities were not perfectly correlated for ozone decomposition. In addition, the catalytic activity the $TiO_2$ added catalyst was decreased, due to the reduction of Mn contents. The structural characteristics of maganase oxide was not associated with the catalytic activity for ozone decomposition.
