摘要: This paper reports the synthesis of flower-like ZnO hierarchical structures via a simple and economical citric acid-mediated hydrothermal route. The as-synthesized was characterized in detail by field-emission scanning electron microscopy (FESEM), energy dispersive X-ray, transmission (TEM), X-ray diffraction (XRD), N2 adsorption–desorption, UV–visible absorption, Fourier-transform infrared (FTIR), Raman analysis. FESEM TEM showed that an assembly large numbers interleaving nanosheets average thickness approximately 88 nm. XRD, FTIR, results products were highly crystalline with wurtzite structure. Photocatalytic tests indicated had efficient photocatalytic activity degradation phenol under UV irradiation. further confirmed formation intermediates, identified use high-performance liquid chromatography, decrease total organic carbon concentration. reused several times without appreciable loss activity. These characteristics structure is suitable for practical applications environmental remediation.
