文摘
The photocatalytic preferential oxidation of CO with O2 in the presence of H2 was seen to proceed efficientlyon Cr6+-MCM-41 with high CO conversion and selectivity under visible light (
> 420 nm) or solar lightirradiation at 293 K. Photoluminescence and FT-IR investigations show that the redox cycles of Cr-oxidespecies were found to play significant roles in the selective oxidation reaction of CO in the presence of H2.
