Key Points

ZnTe/ZrS2 heterojunction enhances water splitting efficiency through improved carrier separation.
STH efficiency of 14.296% indicates strong redox power in the Z-scheme photocatalysis.
ZnTe serves as the hydrogen evolution reaction (HER) site, while ZrS2 acts as the oxygen evolution reaction (OER) site.
Theoretical modeling reveals band bending forces that facilitate effective charge recombination management.

Implication

Theoretical design demonstrates Z-scheme photocatalyst achieves 14.296% STH efficiency, improving carrier separation.

Abstract

BIEF & band bending force exclusive path 2 recombination, proving Z-scheme. This boosts carrier separation while preserving strong redox power. ZnTe side is HER site, ZrS 2 OER site. ZnTe/ZrS 2 heterojunction achieves 14.296% STH efficiency.
