Abstract
Polyoxometalate (POM)-pillared Zn–Cr layered double hydroxides (LDHs) exhibited high photocatalytic activities in CO2 reduction and H2O oxidation reactions. For CO2 reduction in pure water, the CO production was 1.17 μmol g−1 after a 24 h reaction. For O2 evolution in NaIO3 solution, the O2 production reached 148.1 μmol g−1 after a 6 hour reaction. A mechanism study indicated that the electron transfer from Zn–Cr LDHs to POMs (SiW12O404−) promoted photocatalytic activities.
