A deposition and photo-activated method was used to prepare the Ag/FeOOH photo-catalyst on montmorillonite (MMT). Different characterization techniques are performed on the Ag/FeOOH/MMT composite to investigate its structure, morphology, valence state and optical property. During the photo-catalytic experiments, a certain amount of Ag can improve the photo-catalytic efficiency of FeOOH/MMT for phenol degradation, and h+ and ∙O2 play the key roles in photo-catalysis according to the radical scavengers experiment. The mechanism of phenol degradation is also explored: The target organic pollutant phenol is degraded to some intermediates with weak acid, eventually to CO2 and H2O. With excellent stability and recyclability, the prepared Ag/FeOOH/MMT is a promising photo-catalyst for wastewater treatment under sunlight.
