Effect of various amounts of graphene oxide on the degradation characteristics of the ZnSe/graphene nanocomposites

When the ratio of the addition of GO to the amount of ZnSe-N2H4 increases from 0.25 to 1, the degradation effect of GN-5 ml ZnSe on MB increases with increasing GO; the degradation efficiency of GN-ZnSe for MB increased from 35.4% to 99.6% after 6 h of visible light irradiation, which was the optimum degradation efficiency obtained in the present study. When the ratio of the addition of GO to the amount of ZnSe-N2H4 increased from 1 to 2, the degradation efficiency of GN-5 ml ZnSe for MB decreased with the increasing addition of GO; the degradation efficiency of GN-5 ml ZnSe (2) only slightly decreased to 95.3% after 6 h of visible light irradiation.
