Growth of monodispersed SrTiO3 nanocubes by thermohydrolysis method

SrTiO3 nanocubes were synthesized in aqueous solution with Bis (ammonium lactate) titanium dihydroxide (TALH) as the Ti source under hydrazine-assisted hydrothermal condition. The SrTiO3 nanocubes grew from the Ti-based sol through a dissolution-precipitation process and large cubic particles formed through the oriented aggregation of nanocubes over a long time. The morphology, monodispersibility, and size of the nanocubes were controlled through the concentration and ratio of oleic acid and hydrazine.
