Abstract: A series of doped Co/ZnO photocatalysts are prepared through hydrothermal method and characterized by XRD,SEM and UV-Vis DRS.The results illustrate that the prepared Co/ZnO exhibits a structure of short rod,the width forbidden band of ZnO narrows significantly after doped with Co metal ion and the utilization of visible light by the prepared Co/ZnO is obviously higher than that of pure ZnO.Through evaluating the photocatalytic performance of Co/ZnO in photocatalytic degradation of catechol,it is found that the apparent rate constant of catechol photocatalytic degradation over 4% Co/ZnO is 1.95 times that over pure ZnO.The Co/ZnO prepared at 140℃ after 16 h of hydrothermal reaction has a better photocatalytic activity,over which the degradation rate of catechol can reach 99% under 180 min of illumination by 400 w metal halide lamp.
