Comparison between Conventional and Microwave-Assisted Synthesis of Cu-Containing Layered Double Hydroxides

Abstract:

Cu-containing Layered Double Hydroxides (Cu-LDHs) prepared in a microwave field (Cu-LDHs-b) differs drastically according to the appearance, chemical component and the catalytic activity when compared with conventionally prepared sample (Cu-LDHs-a). From the TEM images, it is obvious that the particle size range of Cu-LDHs-b with 30～90 nm is narrower than that of Cu-LDHs-a with 30～120 nm, and the dispersibility of Cu-LDHs-b is better than that of Cu-LDHs-a. ICP-AES characterization shows that raw material utilization ratio of Cu-LDHs-b is higher than that of Cu-LDHs-a. Furthermore, Cu-LDHs-b exhibites higher catalytic activity than Cu-LDHs-a in the phenol hydroxylation with H2O2. Therefore, the microwave-assisted synthesis is an ideal method for synthesis of nano-Cu-LDHs.
