N2 - MnO2/Ni(OH)2 was grown in situ on three-dimensional nickel foam (NF), which was then used to activate potassium persulfate (PS) for orange II (OII) degradation. The structure and morphology of the prepared materials were characterized by X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The removal efficiency of OII was 98.68% with MnO2/Ni(OH)2@NF/PS system in 40 min. The three-dimensional hierarchical structure of mesoporous material promoted the efficient and fast electron transfer during catalytic activity. Based on classical quenching experiments and the electron spin resonance experiments, ·OH and SO4·− were identified as the active species in MnO2/Ni(OH)2/NF/PS system for OII degradation and a degradation mechanism was proposed for this system. Compared with traditional micro-nano particle catalysts, 3D MnO2/Ni(OH)2@NF has the advantages of convenient recovery and good stability. MnO2/Ni(OH)2@NF catalyst could be recycled for at least three times, and the degradation rate was 89.06% after three cycles. This MnO2/Ni(OH)2@NF is expected to be used as a green heterogeneous catalyst.
