Abstract
Photocatalysis is an economical and reliable method for degradation of pharmaceutical pollutants. Under mild conditions, the photocatalyst can absorb optical energy and accelerate the photo degradation of pollutants. As a new type of non-metallic semiconductor catalyst, graphite phase carbon nitride(g-C3N4) has many excellent properties such as low band gap, large specific surface area and so on. Norfloxacin (NOR) is a synthetic antibiotic with many good properties such as high antibacterial activity and low toxicity. Because of its wide application in medical treatment and animal breeding, it has caused great pollution to the environment. In this paper, the performance of g-C3N4 and the mechanism of photocatalytic degradation of NOR are analyzed. Several effective modification methods are described, and several problems that need to be solved in current research are put forward.
