The effects of a-Fe2O3/NiS2 composite for the humic acid removal were systematically studied and compared with the synthesized a-Fe2O3 and NiS2. The obtained mesoporous composite has a stacked plate-like surface, active at a visible light region with a bandgap of 2.49 eV, and has a lower rate of rec...
