Abstract

Nano Cu-Zn-Al-ZSM-5 was directly synthesized in HCl solutions with the promotion of ultrasound. XRD results show that the appropriate concentrations of HCl in the synthetic process were between 0.25 M and 1 M, and the optimal crystallization time and temperature were 28 h and 200°C, respectively. The ultrasound irradiation can significantly increase the crystallization of Cu-Zn-Al-ZSM-5 within 0.5 h. SEM photographs of Cu-Zn-Al-ZSM-5 zeolite showed the crystal size is about 50–60 nm. Results of ICP/AES show that the weight% of Cu in 101(Cu-Zn-Al-SOD) and 202(Cu-Zn-Al-ZSM-5) were 4.42% and 2.30%, respectively.
