An efficient one‐step thermolysis method is developed to fabricate an optically active and well‐ordered array of zinc oxide ( ZnO )@C core@shell hexagonal ( ZCCSH ) nanorods. These nanorods containing oxygen vacancy defects are synthesized using zinc acetate dihydrate under sealed conditions by a thermolysis reaction, and exhibit strong light absorption throughout the visible region and in most of the near‐ IR region. ZCCSH nanorods are converted to carbon nanotubes ( CNTs ) by a simple acid treatment with a high dispersion concentration (1.83 mg/ mL ) in an organic solvent. The CNTs exhibit good electrical conductivity (6100 S/m). The morphology, structure, and interface characteristics of ZCCSH and CNTs are investigated.
