| Abstract: | The novel flower-like GN/ZnO architectures composed of curved cone are synthesized with hydrothermal method at 120?°C for 4?h. The GN/ZnO composite was doped with GN during preparation, the photocatalytic activity of GN/ZnO was evaluated by photodegradation of Rhodamine B (RhB) under simulated visible light. The results showed that the photocatalytic activity of α-CNTs/SnO2 for degradation of RhB was up to 90% within 50?min, which was much higher than that of pure compound. It was significantly found that the introduction of GN, which may suppressed the recombination of photogenerated electron-hole pairs on the interface of SnO2, leading to enhanced photocatalytic activity. |
