Improving built-in electric fields for effective photocatalytic activity in the rationally designed electron transfer pathway of TiO2@MoS2/Bi2S3

An augmented built-in electric field was successfully fabricated within TiO 2 @MoS 2 /Bi 2 S 3 . DFT calculations reveal electron accumulation and depletion at the heterointerface, demonstrating unique electron transfer pathway directed towards MoS 2 .
