Hierarchical architecture of cubic sillenite bismuth titanate (Bi₁₂TiO₂₀) is successfully synthesized using simple ethylene glycol-mediated self-assembly; followed by calcination under air at 600°C for 30min. The products are characterized using field emission scanning electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FT-IR), thermogravimetric-differential thermal analysis (TG-DTA), and X-ray diffraction (XRD). The reaction time has an effect on the product morphology, which changed from a leaf- and circular plate-like structure to a completely formed hierarchical structure within 2h. The hierarchical structure of Bi₁₂TiO₂₀, having a size around 3μm, is composed of 2D twist nanoplates, and each twist nanoplate has a thickness around 10–30nm.
