Amine-Functionalized Titanate Nanosheet-Assembled Yolk@Shell Microspheres for Efficient Cocatalyst-Free Visible-Light Photocatalytic CO<sub>2</sub> Reduction
Exploiting
advanced semiconductor photocatalyst with superior activity and selectivity
for the conversion of CO<sub>2</sub> into solar fuels and valuable
chemicals is of worldwide interest. In this report, hierarchical amine-functionalized
titanate nanosheets based yolk@shell microspheres were synthesized
via one-pot organic amine mediated anhydrous alcoholysis of titanium(IV)
butoxide. The selected organic amine, diethylenetriamine, played multiple
roles. First, it was essential for the crystallographic, morphological
and textural control of the synthesized titanate nanoarchitectures.
Second, it was crucial for the in situ functionalization of titanate
nanosheets by concurrent interlayer intercalation and surface grafting,
which gave rise to the strong visible-light absorption ability and
high CO<sub>2</sub> adsorption capacity. As a consequence of the synergetic
tuning in multilevel microstructures, an integrated engineering of
the multifunctional modules of the titanate-based photocatalysts was
achieved for efficient CO<sub>2</sub> reduction toward solar fuels
