The barium titanate (BaTiO3, BT) epitaxially coated strontium titanate (SrTiO3, ST) (BT/ST) nanocube accumulation ceramics were successfully prepared by a sorbothermal method, with epitaxial interface between ST and BT, and as reference, the BT/BT nanocube accumulation ceramics were also preapred. These dielectric properties were measured for the both accumulation ceramics, and it was clearly obserbed that there was significiant difference between BT/ST and BT/BT nanocube accumulation ceramics in the dielectric properties under low and high electric fields, and the origin of the result was discussed.

Epitaxial Interface

The strontium titanate (SrTiO3, ST) -coated barium titanate (BaTiO3, BT) complex nanoparticles was prepared. Using this condition, ST-coated BT (ST/BT) and ST-coated ST (ST/ST) nanocube accumulation ceramics were successfully prepared with epitaxial interface between ST and BT. Dielectric properties were measured for the both accumulation ceramics, but there was no difference of the dielectric properties between both ceramics, and the origin of the result was discussed.

Photocatalytic Applications

<p>Nanohybrids, made up of Bismuth ferrites/Carbon allotropes, are extensively used in photocatalytic applications nowadays. Our work proposes a nanohybrid system composed of Bismuth ferrite nanoparticles with two-dimensional (2D) MXene sheets namely, the BiFeO<sub>3</sub> (BFO)/Ti<sub>3</sub>C<sub>2</sub> (MXene) nanohybrid for enhanced photocatalytic activity. We have fabricated the BFO/MXene nanohybrid using simple and low cost double solvent solvothermal method. The SEM and TEM images show that the BFO nanoparticles were attached onto the MXene surface and in the inter-layers of two-dimensional (2D) MXene sheets. The photocatalytic application is tested for the visible light irradiation which showed the highest efficiency among all pure-BFO based photocatalysts, i.e. 100% degradation in 42 min for organic dye (Congo Red) and colorless aqueous pollutant (acetophenone) in 150 min, respectively. The present BFO-based hybrid system exhibited the large surface area of 147 m<sup>2</sup>g<sup>-1</sup>measured via Brunauer-Emmett-Teller (BET) sorption-desorption technique, and is found to be largest among BFO and its derivatives. Also, the photoluminescence (PL) spectra indicate large electron-hole pair generation. Fast and efficient degradation of organic molecules is supported by both factors; larger surface area and lower electron-hole recombination rate. The BFO/MXene nanohybrid presented here is a highly efficient photocatalyst compared to other nanostructures based on pure BiFeO<sub>3</sub> which makes it a promising candidate for many future applications.</p>
