主　　题：Graphene Oxide Films Green Reduction Near Ultraviolet Light L-Ascorbic Acid Wide-Angle X-Ray Scattering 

摘      要：Recent studies have highlighted the effects of various stimuli on the chemical reduction of graphene oxide(GO)through green reductant L-ascorbic acid(L-AA);however,the combination of near ultraviolet(NUV)light to increase the reduction rate has yet to be thoroughly *** this study,drop-casted GO films were subjected to chemical reduction through L-AA with various levels of exposure under 405 nm NUV *** structure and uniformity of GO stackings that form the film were characterized through scanning electron microscopy(SEM)and wide-angle x-ray scattering(WAXS).Additionally,WAXS was used to track the removal of oxygen-containing functional groups along with Fourier-transform infrared(FT-IR)spectroscopy and x-ray photoelectron spectroscopy(XPS)as a function of L-AA and NUV light exposure *** results demonstrated that the interaction between L-AA and NUV exposure has a significant effect on the reduction of ***,the results that yielded the highest reduction(C-C bond concentration of 60.7%)were the longest L-AA and NUV light exposure times(48 hours and 3 hours,respectively).This report provides a study on the effects of NUV on the green reduction of GO films through L-AA with potential application in solar energy and chemical sensing applications.
