A novel visible light-driven photocatalyst, lithium vanadium phosphate sphere(LVPS), was prepared by a ball-milling method. For enhancing the photocatalytic performance, LVPS was further modified with silver(ALVPS) by a UV-light photo- reduction method. After modification, the crystalline phase of LVPS did not change, however, the UV-Vis diffuse reflectance spectrum of ALVPS was extended to 656 nm, which greatly improved its photoabsorptivity for visible light and enhanced its electron donating capacity. Under the irradiation of sunlight or visible light(>400 nm), ALVPS can rapidly remove fipronil(a persistent organic pollutant, 5 mg L?1) from aqueous solution. More than 99.7% of fipronil was removed by ALVPS after 0.5 h of irradiation, yielding a much higher removal rate than those achieved by nano-Ti O2 and Bi2O3. Photo-generated carrier trapping experiments were conducted to elucidate the photocatalytic degradation mechanism further. Hydrogen peroxide and potassium bromate suppressed the photocatalytic activity of ALVPS, while superoxide dismutase and sodium azide reinforced it, verifying that photo-generated electrons played a key role in the photochemical reaction.
