Synthesis and defect structure of quasi-one-dimensional composite material ZnO/ZnS

Resumo

Nanostructured composite material ZnO/ZnS based on ZnO nanocrystalline nanotubes has been produced by the chemical bath deposition method. To retain the morphology of ZnO nanotubes, their surface was modified through chemical substitution of sulfur atoms for surface oxygen atoms and oxygen vacancies. The content of deposited ZnS nanoparticles depends on the nature of the sulfiding agent, pH, and the type of ligand. The morphological features of polycrystalline ZnO nanotubes remain unaltered in the course of long-term treatment of ZnO nanotubes in a sulfiding agent solution.
