英文摘要	Sparked by the growing environmental crises, photocatalytic degradation of chlorophenols with inexhaustible solar energy is expected to be converted into actual applications. Here, we report the preparation of the nanocomposite of Cu-2(OH)PO4 and reduced graphene oxide (Cu-2(OH)PO4/rGO) through a one-step hydrothermal method and examined its infrared-light photocatalytic activity in the degradation of 2,4-dichlorophenol (2,4-DCP). As evidenced by the absorption spectra and the degradation of 2,4-DCP, Cu-2(OH)PO4/rGO exhibited enhanced infrared light-driven photocatalytic activity compared to pure Cu-2(OH)PO4 and was very stable even after repeated cycling. More importantly, the introduction of hydrogen peroxide (H2O2) could combine the photocatalytic and photo-Fenton effects into one reaction system and maximize the infrared light photocatalytic efficiency. Typically, the rate constant of Cu-2(OH)PO4/rGO and H2O2 was more than 6.25 times higher than that of only Cu-2(OH)PO4/rGO, and almost 10 times greater than the value for pure Cu-2(OH)PO4. Further, a plausible mechanism for the enhanced photocatalytic properties of Cu-2(OH)PO4/rGO has been discussed. These findings may help the development of novel hybrid photocatalysts with enhanced infrared light photocatalytic activity for applications in the treatment of chlorophenol-contaminated wastewater.
