Abstract
The ZMF@S10 composite that was synthesized by using spent Zn-Mn batteries and abandon SCR catalyst as the starting materials for magnetic photocatalysts with high photocatalytic activity is successfully prepared in this study. The results showed that the core TiO2 crystal structure will transform from anatase to rutile, which was then covered in the ZMF. The efficient photocatalytic performance of the composites under visible light is due to the inhibition of the recombination rate of photogenerated dots and holes on the surface of ZMF by the presence of rutile TiO2. Besides, all composites show good stability, regeneration performance, and easy recycling.
