The application of photocatalytic technology to functional materials and environmental protection has attracted great attention of researchers. In the present work, a new method to apply titania-bearing blast furnace slag (TBBFS), high-titania slag (HTS) and concentrated titania ore (CTO) as the raw materials for making photocatalytic materials was proposed, aiming at an integrated utilization of resources and low-cost fabrication of semiconducting photocatalytic materials. Through photocatalytic degradatio...
