A green hydrothermal method was proposed for the controllable synthesis of ZnO₂nanocrystals and ZnO nanorods, using the common and cost-effective 2ZnCO₃·3Zn(OH)₂powder and 30 mass% H₂O₂ aqueous solution as the raw materials. The characterization results from X-ray diffraction, high resolution transmission electron microscopy, transmission electron microscopy and energy dispersive X-ray spectroscopy indicated that the products synthesized at 100–120 °C for 6 h or at 170 °C for 0 h were cubic phase ZnO₂nanocrystals; while those synthesized at 170 °C for 3–6 h were hexagonal phase ZnO nanorods. The UV–vis absorption spectra showed that the as-synthesized ZnO₂nanocrystals and ZnO nanorods had optical band gaps of about 4.1 and 3.3 eV, respectively.
