Photocatalytic performance of polyoxometallate intercalated layered double hydroxide

摘要

Based on X-ray diffraction results, the gallery height of modified Mg3Al-LDH was expanded to 9.6A from the original 4.8A, indicating that the H_3PW_(12)O_(40) was indeed inserted into the hydroxide layers. Moreover, the results of FT-IR spectra proved the Keggin structure of PW_(11)O_(39)~(7-) species. The resulting material showed a high activity of degradation of methyl orange in the presence of H_2O_2 and UV light irradiation.
