NOVELTY - Use of porous carbon nitride-reduced graphene oxide (RGO)-titanium dioxide nanobelt catalytically activated persulfate for oxidative degradation of 17-α-ethinylestradiol by activated persulfate. USE - The nanobelt is useful for oxidative degradation of 17-α-ethinylestradiol by activated persulfate (claimed). ADVANTAGE - The nanobelt only adds 1 mM persulfate, and when degraded for 6 minutes, the removal rate of 6 mg/l 17-α-ethinyl estradiol reaches 100%, which is greatly improved compared with the removal rate of pure photocatalytic degradation (20.89%). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a used method of the porous carbon nitride-reduced graphene oxide (RGO)-titanium dioxide nanobelt, comprising adding the porous carbon nitride-RGO-titanium dioxide nanobelt into 17-α-ethynyl estradiol, stirring for 120 minutes in a dark place, adding persulfate, and turning on the xenon lamp, adding filter to conduct visible light catalytic activation of persulfate for oxidative degradation of 17-α-ethynyl estradiol.
