Internal electric field promoted charge separation via bismuth-based ternary heterojunctions with near-infrared light harvesting properties for efficient photoredox reactions

This study highlights the single-step growth of Bi/Bi 2 WO 6 /Bi 2 S 3 on CdS nanorods and their built-in electric field modulated charge separation toward a UV-vis-NIR driven photocatalytic H 2 evolution reaction.
