Abstract
- Abstract: We have developed an environment-friendly low-temperature chemical precipitation approach for the accurate coating of ZnO nanocrystals onto nitrogen-doped carbon nanotubes(N-CNTs) to form ZnO/N-CNTs nanohybrids, which only use zinc acetate dehydrate, N-CNTs and NaOH as initiating materials without employing any additional surfactant and react in ethanol at 60°C for 2h. Through this facile process, the as-obtained nanohybrids preserve the good dispersity and uniformity of initial N-CNTs and the loading amount of the ZnO nanocrystals can be conveniently varied or controlled by the concentration of the zinc precursor. Furthermore, the products exhibit the enhanced visible-light photocatalytic activity for the degradation of rhodamine B (RhB) and benzoic acid. It is believed that this simple strategy can be extended to synthesize other metal-oxide/N-CNTs nanohybrids for different applications. [Copyright &y& Elsevier]
