Photosynthesis and characterization of Prussian blue nanocubes on surfaces of TiO_2 colloids

摘要

Prussian blue (PB) nanocubes were synthesized on the surface of titania (TiO_2) colloids using two-step process with ultraviolet light illumination. The formation of PB nanocubes starts with its nucleation under strong ultraviolet light illumination and followed by a slow growth of the nuclei under low intensity natural light illumination. This kind of PB nanocube has a very low Curie temperature.
