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.

Ce-containing Layered Double Hydroxides (Ce-LDHs) were prepared by conventional and microwave-assisted crystallization method, which were denoted as Ce-LDHs-A and Ce-LDHs-B, respectively. The dispersibility of Ce-LDHs-B is much better than that of Ce-LDHs-A; the particles of Ce-LDHs-B with particle size ranging from 20 to 70 nm are smaller than that of Ce-LDHs-A with sizes around 50-300 nm. The effect of the cerium to aluminum molar ratios, microwave crystallization time and reaction temperature on the structure of Ce-LDHs was also investigated. The results show the excessive Ce into LDHs causes distortion of the samdwich, the damage of the LDHs structure becomes more and more serious with increasing the proportion of Ce/Al. The structure of Ce-LDHs becomes more and more perfect with the increasing of the microwave crystallization time and reaction temperature.
