DOI: 10.1039/C3DT52120F, PaperJingjing Xu, Mindong Chen, Zhengmei Wang
Reduced graphene oxide/CdWO4 (RGO-CdWO4) nanorod composite photocatalysts were prepared by a simple one-pot method. Namely, the reduction of graphene oxide and the growth of CdWO4 nanorod occurred simultaneously in one single process. An enhancement in photocatalytic activities were observed on RGO-CdWO4 composites compared with pure CdWO4 under UV light irradiation.
