Modularization
of Regional Electronic Structure over
Defect-Rich CeO2 Rods for Enhancing Photogenerated Charge
Transfer and CO2 Activation
Posted on 2024-04-03 - 13:08
Oxygen vacancy (OV) engineering has been widely applied
in different
types of metal oxide-based photocatalytic reactions. Our study has
shown that the redistributed OVs resulting from voids in CeO2 rods lead to significant differences in the band structure in space.
The flat energy band within the highly crystallized bulk region hinders
the recombination of photogenerated carrier pairs during the transfer
process. The downward curved energy band in the surface region enhances
the activation of the absorbents. Therefore, the localization of the
band structure through crystal structure regionalization renders V-CeO2 capable of achieving efficient utilization of photogenerated
carriers. Practically, the V-CeO2 rod shows a remarkable
turnover number of 190.58 μmol g–1 h–1 in CO2 photoreduction, which is ∼9.4 times higher
than that of D-CeO2 (20.46 μmol g–1 h–1). The designed modularization structure in
our work is expected to provide important inspiration and guidance
in coordinating the kinetic behavior of carriers in OV defect-rich
photocatalysts.
