P-block-based Ferroelectric-photocatalyst compounds: Structure, Ferroelectric properties and photocatalytic performance

The high recombination rates of photogenerated electron-hole pairs inside the bulk of photocatalyst, the back-reactions of intermediate species and inactive visible light are regarded as the key issues blocking solar light-conversion efficiency. P-block photocatalyst based-internal electric field compounds are regarded as a much attractive attention for photocatalysts because of their dispersive and anisotropic band structures, as well as their intrinsic internal electric field. The driving force of charges separation via internal electric field plays a key role to reduce recombination rates. In this thesis, it is divided into three parts by using three p-block photocatalyst based-internal electric field compounds:
