Abstract

Cu₂(OH)₃(NO₃)/few-layer graphene nanocomposites are the promising catalysts in azo dyes removal and are the research focuses. In this study, the pulsed discharge of HNO₃-treated graphite strip was carried out in Cu(NO₃)₂ solvent. The recovered samples were characterized by multiple techniques, including TEM, SEM, AFM, XRD and XPS. The corresponding characterization results show that the recovered sample features the morphology of various Cu₂(OH)₃(NO₃) nanosheets were anchored on the surface of few-layer graphene. In the recovered sample, the matrix, few-layer graphene, are in lateral size of 8–25 μm, thickness of 2–5 layers. The Cu₂(OH)₃(NO₃) nanosheets is in lateral size of 2–5 μm with thickness of 75 nm. The formation mechanism of Cu₂(OH)₃(NO₃)/few-layer graphene (FLG) during pulsed discharge is also discussed based on the experimental conditions and results. Our studies demonstrate an efficient and cost-effective route to produce Cu₂(OH)₃(NO₃)/FLG nanocomposite materials.
