Ferroelectric polarization promotes the excellent CO2 photoreduction performance of Bi4Ti3O12 synthesized by molten salt method

Pengwei Jia et al.

Summary: The coupling of ferroelectric and photoexcitation can effectively enhance the catalytic performance of semiconductors. By utilizing the spontaneous polarization of strong ferroelectric materials to induce the separation of electrons and holes, directly developing ferroelectrics as photocatalysts shows great promise. In this study, a ferroelectric layered perovskite Bi4Ti3O12 was prepared through molten salt method (BTO-1) and hydrothermal method (BTO-2), and it exhibits excellent photocatalytic performance for CO2 reduction. Compared to BTO-2, BTO-1 shows stronger photoexcited carrier separation ability and larger specific surface area, leading to significantly higher CH3OH and CH3CH2OH yields. The exceptional ferroelectric properties of BTO-1, resulting from its remarkable crystallinity, effectively reduce the recombination of photogenerated carriers induced by an electric field, thereby greatly enhancing its photocatalytic performance. The yields of CH3OH and CH3CH2OH after CO2 reduction by polarized BTO-1 are 1.84 and 1.61 times higher than those of unpolarized BTO-1, respectively. This study opens up new possibilities for utilizing ferroelectric materials as efficient photocatalysts to improve photocatalytic ability.

Intrinsic photocatalytic water oxidation activity of Mn-doped ferroelectric BiFeO3

Jafar Hussain Shah et al.

Summary: In this study, particulate BFO and Mn-doped BiFeO3 were synthesized by the sol-gel method, demonstrating that Mn doping significantly enhances the oxygen evolution reaction (OER) activity under visible light irradiation. The bandgap of Mn-doped BFO could be reduced by varying the Mn doping amount, leading to improved absorption of visible light and decreased activation energy for water oxidation. Density functional theory (DFT) calculations suggested that surface Fe species are the active sites for water oxidation, with Mn doping leading to the lowest over-potential measured in this study. The synergistic effect of bandgap narrowing in Mn-doped BFO increases the photocatalytic water oxidation activity by inhibiting charge recombination and reducing activation energy.
