Synthesis of 3D hierarchical CuS architectures consisting of 1D nanotubes for efficient photocatalysts

3D hierarchical CuS architectures consisting of 1D nanotubes have been synthesized by the combination of the self-assembly method and a simple solvothermal process. The hierarchical structures not only provide a large number of active sites on the surfaces, but also integrate the advantages of 1D nanotubes for molecular or ionic transport and 3D for mechanical stability. The hierarchical CuS architectures can be a Fenton-like catalyst with excellent catalytic performance. The degradation rate constant k of 3D hierarchical CuS is 8.37 × 10⁻² min⁻¹ at the concentration of rhodamine B (RhB) of 50 mg/mL under visible light irradiation.
