“…Recently, Cu-based catalysts have attracted considerable attention because the redox properties of copper are similar to iron, and the Cu-based Fenton-like system could work over a broader pH range than the Fe-based redox system [13,14] ), can efficiently produce Å OH [13,15,16]. Due to the mobilization of Cu(II)/Cu(I) in water, copper has been suggested to be supported on a porous solid substrate.…”
