By this method, the crystal form and grain size of theimmobilized TiO_2 were well maintained. Compared with TiO_2 powder, the photocatalytic activity ofTiO_2/PS thin films was not significantly reduced. The catalyst is stable and can be reused severaltimes without the loss of activity, which makes wastewater treatment using this photocatalyticdegradation technique of this way possible in the practical application.展开更多
