摘要: Abstract ZnO nanorods were prepared via a green and surfactant-free hydrothermal approach using powder 30 vol% H 2 O aqueous solution. X-ray diffraction results revealed that the synthesized product was highly crystalline having hexagonal wurtzite structure. The band gap energy of determined to be 3.28 eV optical reflectance spectrum. rod-like morphological features nanostructures observed from field-emission scanning electron microscopy, transmission microscopy high-resolution microscopy. showed an enhanced photocatalytic performance compared commercial TiO for phenol degradation, which could ascribed its special structure feature. Nb 5 /ZnO Cr 3 nanocomposites also displayed efficiency after decorating metal oxide nanoparticles on surface nanorods.
