Abstract
The work reported the rapid synthesis of nano zeolitic imidazolate framework-8 (ZIF-8) crystals at room temperature in the methanol with the support of ultrasound, and the preparation of porous ZnO by calcination of the ZIF-8 material in the air. The photocatalytic activity of the obtained materials was evaluated through the degradation of methylene blue (MB) under UV irradiation. The results indicated that ZIF-8 and the materials obtained by ZIF-8 heat treatment have photocatalytic activity. However, the MB degradation photocatalytic performance of ZnO samples derived from ZIF-8 was still lower than that of the ZIF-8 samples, indicating that ZIF-8 is an effective photocatalyst for organic pollutant degradation.
