Abstract

The aim of this work was to study the catalytic performance of Bi₂WO₆-Fe₃O₄/rGO on the rhodamine B degradation using H₂O₂ activation with visible light. Characteristics of the Bi₂WO₆-Fe₃O₄/rGO catalyst were analyzed via various techniques. The results displayed that the optimum conditions (16 mg L⁻¹ pollutant, nanocomposite value 0.8 g L⁻¹, 2.6 mM H₂O₂, pH 5), the elimination efficiency of rhodamine B 96 % was obtained after 40 min. Moreover, the radical scavenger experiments confirmed that hydroxyl radical (OH^•) and superoxide radical (O₂^∙-) contributed to the pollutant degradation, and OH^• has a dominant role. In addition, Bi₂WO₆-Fe₃O₄/rGO exhibited the good stability and reusability. This study illustrated that the simultaneous presence of Bi₂WO₆-Fe₃O₄/rGO with H₂O₂ has a high potential for the degradation of organic pollutant.

期刊介绍： FlatChem - Chemistry of Flat Materials, a new voice in the community, publishes original and significant, cutting-edge research related to the chemistry of graphene and related 2D & layered materials. The overall aim of the journal is to combine the chemistry and applications of these materials, where the submission of communications, full papers, and concepts should contain chemistry in a materials context, which can be both experimental and/or theoretical. In addition to original research articles, FlatChem also offers reviews, minireviews, highlights and perspectives on the future of this research area with the scientific leaders in fields related to Flat Materials. Topics of interest include, but are not limited to, the following: -Design, synthesis, applications and investigation of graphene, graphene related materials and other 2D & layered materials (for example Silicene, Germanene, Phosphorene, MXenes, Boron nitride, Transition metal dichalcogenides) -Characterization of these materials using all forms of spectroscopy and microscopy techniques -Chemical modification or functionalization and dispersion of these materials, as well as interactions with other materials -Exploring the surface chemistry of these materials for applications in: Sensors or detectors in electrochemical/Lab on a Chip devices, Composite materials, Membranes, Environment technology, Catalysis for energy storage and conversion (for example fuel cells, supercapacitors, batteries, hydrogen storage), Biomedical technology (drug delivery, biosensing, bioimaging)
