ZnFe2O4/AC composites were prepared by the one-pot hydrothermal method using the activated carbon (AC) as a carrier. The\nsynthesis conditions were optimized by a single-factor experiment.Thestructural, textural, and surface properties of the adsorbent\nhave been comprehensively characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform\ninfrared (FT-IR) spectroscopy, Brunauerââ?¬â??Emmettââ?¬â??Teller (BET) measurements, and X-ray photoelectron spectroscopy (XPS)\nanalysis. The SO2 removal capacities of the composites were investigated via testing the adsorption capacity at the self-made\ndesulfurization equipment. The results show that the adsorption capacity of ZnFe2O4/AC composites is much higher than that of\nthe AC and ZnFe2O4 samples, respectively. The composite overcomes the disadvantages of the traditional sintering, showing\na very high desulfurization performance. The breakthrough time was 147 min, and the sulfur adsorption capacity could reach\n23.67% in the desulfurization performance test.
