Free-standing single-crystal PbTiO3 nanoplates (see picture) were synthesized by a facile hydrothermal method. A “self-templated” crystal growth is presumed to lead to the formation of the PbTiO3 nanoplates, which have ferroelectric single-domain structures, whose polarization areas can be manipulated by writing and reading. The nanoplates are also effective catalysts for the oxidation of carbon monoxide.
