The composite photocatalyst WO3/rGO/BiOBr(WRB) was prepared by solvothermal method. BiOBr was assembled into the WO3 nanotube beam loaded with rGO. WRB was characterized by X-ray diffraction(XRD). scanning electron microscopy(SEM). https://www.bekindtopets.com/super-super-Handlebar-Stem-for-the-GOTRAX-GXL-V2-Electric-Scooter-hot-choice/
