Tóm tắt

Peanut‐like and flower‐like zinc oxide 3D architectures were synthesized via a facile biomimetic process using gelatin as matrix. Techniques of XRD, SEM, HRTEM, FT‐IR, and UV‐vis absorption spectra were used to characterize the structure and property of the zinc oxide architectures. The experimental results show that the peanut‐like ZnO and flower‐like ZnO architectures can be obtained through changing the Zn2+ concentration or the aging time. FT‐IR spectra indicate that the Zn2+ is coupled with the C=O bond of the gelatin molecules through the electrostatic interaction. Based on the experimental process, the possible growth mechanism of the ZnO 3D architectures is proposed. UV‐vis absorption spectrum of the peanut‐like ZnO has a broad absorption band in the UV region, and the blue‐shifting of the band is observed.
