Synthesis of polyoxometalate-pillared Zn-Cr layered double hydroxides for photocatalytic CO₂ reduction and H₂O oxidation.

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 (SiW₁₂O₄₀^4-) promoted photocatalytic activities.
