with an average size of have been synthesized by a simple hydrothermal reaction with a yield of . After the as-prepared was treated with NaOH solution, the green crystals were converted to blue sisal-like with needle-like nanorods pointing out radially from the core. These nanorods were about 100–200 nm in diameter and in length. Using the sisal-like as sacrificial precursor, CuO with a well-preserved morphological feature of the precursor was formed through thermal treatment. The samples were characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, X-ray photoelectron spectroscopy, BET nitrogen adsorption, and UV-visible absorption spectroscopy. The conversion of the synthesized to sisal-like was optically visualized and confirmed by corresponding SEM images, and an “etching-and-growing” mechanism was proposed. The results also show that the as-prepared CuO possesses a band gap of 2.27 eV and high specific surface area , and its surface is highly rich in O.
