Abstract
By using microwave technique, the high dispersion of CuCl2 in NaZSM-5 zeolite (CuCl2·2H2O/NaZSM-5 ratio of 0–0.50 g/g) has been prepared. The mechanical mixture of CuCl2-2H2O and NaZSM-5 (CuCl2·2H2O/NaZSM-5 ratio of 0–0.50 g/g) shows characteristic XRD peaks of both NaZSM-5 and crystalline CuCl2·2H2O. Notably, after reaction of the above samples in a microwave oven for 10 min, the sample XRD patterns only exhibit the peaks assigned to NaZSM-5, while the peaks assigned to crystalline CuCl2·2H2O disappear completely, indicating that CuCl2·2H2O no longer exists in the crystalline state in the CuCl2·2H2O/NaZSM-5 samples. Additionally, in DTA curves, we cannot observe the melting point of CuCl2 in a CuCl2·2H2O/NaZSM-5 sample (CuCl2·2H2O/NaZSM-5 ratio of 0–0.5 g/g) treated in a microwave oven, indicating that there is no CuCl2 crystalline phase in the CuCl2·2H2O/NaZSM-5 samples (CuCl2·2H2O/NaZSM-5 ratio of 0–0.50 g/g).
