| description | <p>Water splitting in the presence of semiconductor photocatalyst under sunlight illumination is one of the potential methods to produce clean hydrogen fuel. Herein, a BaTiO<sub>3</sub>-CoFe<sub>2</sub>O<sub>4</sub> composite photocatalyst was fabricated using facile hydrothermal method and evaluated their structural, optical, morphological and electrochemical properties for their plausible application in photoelectrochemical water-splitting. The cubic phase of CoFe<sub>2</sub>O<sub>4 </sub>and tetragonal phase of BaTiO<sub>3</sub> were proved by X-ray diffraction pattern. The SEM and TEM images of the composite BaTiO<sub>3</sub>-CoFe<sub>2</sub>O<sub>4</sub> had shown the combination of both spherical and needle-like structure. The average diameter of pure BaTiO3 and CoFe2O4 was around 25 and 50 nm respectively, however, the particle size was reduced to 43 nm for BaTiO<sub>3</sub>-CoFe<sub>2</sub>O<sub>4 </sub>composite. The UV-vis band gap analysis revealed that the Eg value of the composite was found in the visible spectrum. The photoelectochemical behavior with 12 mA/cm<sup>2</sup> at 1.7 V applied potential was achieved for the BaTiO<sub>3</sub>-CoFe<sub>2</sub>O<sub>4</sub> hybrid nanocomposite. The electrochemical impedance spectroscopy showed that the prepared BaTiO<sub>3</sub>-CoFe<sub>2</sub>O<sub>4</sub> composite have possessed better charge transfer and recombination kinetics. </p> <h2>Other Information</h2> <p>Published in: Electrochimica Acta<br> License: <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br> See article on publisher's website: <a href="http://dx.doi.org/10.1016/j.electacta.2023.142849" target="_blank">http://dx.doi.org/10.1016/j.electacta.2023.142849</a> </p> |
