The effects of α-Fe₂O₃/NiS₂ composite for the humic acid removal were systematically studied and compared with the synthesized α-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 recombination compared to the α-Fe₂O₃ but higher than the NiS₂. The highest humic acid removal (93.7%) was achieved by the α-Fe₂O₃/NiS₂ composite followed by the α-Fe₂O₃ (88.7%) and NiS₂ (86.4%) at optimum conditions of 0.1 g L^-1 catalyst loading, pH 5, and 30 mg L^-1 initial humic acid concentration. The mineralization achieved 96.8% and the catalyst stable up to the fourth cycle. These encouraging results were due to the better adsorption capacity of the composite, being active in visible light, and quenching of the photoluminescence that led to effective separation of subsequent reduction in the rate of recombination of the charged carriers.

α-Fe的影响₂ ö ₃ / NIS ₂进行了系统研究复合的腐殖酸的脱除，并与合成的α-Fe相₂ ö ₃和NIS ₂。将所获得的介孔复合体具有层叠板状的表面，在与2.49的带隙的可见光区域有源 电子伏特，且具有比的α-Fe重组较低速率₂ ö ₃但比的NiS更高₂。最高腐殖酸的脱除（93.7％）是由达到的α-Fe ₂ ö ₃ / NIS ₂复合，接着由的α-Fe ₂ ö ₃（88.7％）和NiS ₂（86.4％）的最佳条件是：催化剂负载量为0.1  g  L ^-1，pH 5和最初的腐殖酸浓度为30  mg  L ^-1。矿化达到96.8％，并且催化剂稳定到第四个循环。这些令人鼓舞的结果是由于复合材料具有更好的吸附能力，在可见光中具有活性以及光致发光的猝灭，从而有效分离了带电载流子复合速率的后续降低。
