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.

在超声作用下，在盐酸溶液中直接合成了纳米Cu-Zn-Al-ZSM-5。XRD结果表明，合成过程中HCl的适宜浓度为0.25 M至1 M，最佳结晶时间和温度分别为28 h和200°C。超声辐射可在0.5 h内显着增加Cu-Zn-Al-ZSM-5的结晶。Cu-Zn-Al-ZSM-5沸石的SEM照片显示晶体尺寸约为50-60 nm。ICP / AES的结果表明，Cu在101（Cu-Zn-Al-SOD）和202（Cu-Zn-Al-ZSM-5）中的重量％分别为4.42％和2.30％。
