Visible photocatalytic activity enhancement of Zn0.8Cd0.2S by hybridization of reduced graphene oxide

The GZCS shows a good visible light response, which is an importance to develop an effective visible-light driven photocatalyst. ( As is known to all, the UV light only accounts for about 4% of the solar radiation energy, while the visible light (VL) contributes to about 43%). In addition, the supporting material RGO for Zn0.8Cd0.2S (ZCS) nanoparticles effectively enhanced the photodegradation activities of methylene blue under VL irradiation. The GZCS with 5 wt% RGO content, namely, GZCS5.0 exhibited the highest photodegradation efficiency of MB (96%), which was 2.7 times of pure ZCS.
