Abstract
ABSTRACTPhotocatalytic ozonation of organics under simulated solar irradiation with a g-C3N4 nanosheet was investigated. g-C3N4 was prepared by calcinations of urea and characterized by TEM, BET, XRD and UV-Vis. Oxalic acid and bisphenol A were used as model substances to evaluate its catalytic ability. The results showed that g-C3N4 possess 2D nanosheet structure. The degradation ratio of oxalic acid and bisphenol A with g-C3N4/O3/Solar was 1.50 and 1.92 times as great as the sum ratio when it was individually degraded by g-C3N4/Solar and O3, separately. The results of recycling experiment indicated that g-C3N4 catalyst is very stable under experimental conditions.
