Synthesis and improved photoelectrochemical performances of oxygen-deficient TiO₂/black-BaTiO₃/CdS multiple-heterojunction nanoarrays

Abstract

TiO2-based photocatalysts have been extensively studied due to their economic affordability, sensitive photo-responsivity, excellent chemical and thermal stability, and abundance in nature, etc. The insufficient visible-light absorption and photoelectrode efficiency...
