ZnO/graphene-oxide nanocomposite with remarkably enhanced visible-light-driven photocatalytic performance

Graphene Oxide/Zinc Oxide (GO/ZnO) Nanocomposite as a Superior Photocatalyst for Degradation of Methylene Blue (MB)-Process Modeling by Response Surface Methodology (RSM)

“…5,8,20 The main peaks of the XRD pattern of GO/ZnO nanocomposite are shown in Figure 2b. The diffraction peaks of GO/ZnO nanocomposite are similar to those of ZnO nanoparticles and the main peaks of ZnO are observed in the XRD pattern of the nanocomposite.…”

“…5 Meanwhile, graphene oxide (GO) is receiving increasing attention because it possesses the similar properties to graphene as well as the special surface structures with the introduced hydroxyl and carboxyl groups for the synthesis of GO-containing nanocomposites. 8 A considerable number of articles have been published regarding removal of harmful compounds from water, wastewater and air, using photocatalytic methods, which imply the importance of the mentioned method in removing pollutants. [8][9][10][11][12][13][14] There are various reports [15][16][17][18] on the application of ZnO and TiO 2 nanoparticles as photocatalysts for the degradation of dyes using response surface methodology.…”

Preparation of Modified Graphene Oxide Nanomaterials for Water and Wastewater Treatment

“…Bahnemann et aldegraded methylene blue by TiO2 loaded TiO2-GO, the photocatalytic degradation rates of MB by TiO2-GO were 3 times faster than that by P25 [18]. In our previous study [19], we fabricated Fe2O3 nanoparticles well-distributed hollow reduced graphene oxide microspheres via a spray-drying methodology, the prepared Fe-rGOS exhibited a remarkable photocatalytic activity to methylene blue (MB) in a wide pH range. In addition, metal oxide loaded GO also can be applied to the reduction of hypertoxic heavy metal ions and some micro-molecular organics.…”

ZnO on Thiolated Graphene Oxide as Efficient Photocatalyst for Degradation of Methylene Blue

“…Recently, some researchers have reported that GO-supported catalysts also exhibit better photocatalytic efficiency than pure ZnO particles. [18][19][20][21][22][23] In this paper, we report a simple and effective process for preparation of GO-supported ZnO (GO-ZnO) using thiolated GO as an efficient photocatalyst for photodegradation of methylene blue (MB).
