Enhanced solar absorption and visible-light photocatalytic and photoelectrochemical properties of aluminium-reduced BaTiO3 nanoparticles

Abstract

Enhanced solar light absorption and photocatalytic and photoelectrochemical properties have been achieved in black BaTiO₃ with a unique core/shell structure (crystalline BaTiO₃@amorphous BaTiO_3−x) using an Al-reduction method. This finding may open a new avenue to tune the inert ferroelectric materials toward excellent photocatalysts for advanced applications.
