Self-assembled 3D flower-like perovskite PbTiO3 nanostructures and their application in the catalytic oxidation of CO

3D flower-like PbTiO₃ nanostructures self-assembled with (101) nanosheets have been realized via a facile hydrothermal route and show excellent ability to enhance the catalytic activity of Pt as supports for the oxidation of CO because of the mesoporous structures and high specific surface area.
