A superlattice interface and S-scheme heterojunction for ultrafast charge separation and transfer in photocatalytic H₂ evolution.

ABSTRACT: The rapid recombination of photoinduced charge carriers in semiconductors fundamentally limits their application in photocatalysis. Herein, we report that a superlattice interface and S-scheme heterojunction based on Mn_0.5Cd_0.5S nanorods can significantly promote ultrafast charge separation and transfer. Specifically, the axially distributed zinc blende/wurtzite superlattice interfaces in Mn_0.5Cd_0.5S nanorods can redistribute photoinduced charge carriers more effectively when boosted by homogeneous internal electric fields and promotes bulk separation. Accordingly, S-scheme heterojunctions between the Mn_0.5Cd_0.5S nanorods and MnWO₄ nanoparticles can further accelerate the surface separation of charge carriers via
