Abstract Constructing heterojunctions represents a crucial strategy for enhancing semiconductor
photocatalysts. In this study, the C-MoO2/Cd0.9Zn0.1S S-scheme heterojunction composite
was successfully fabricated through a self-assembly approach. XPS analysis confirmed the
spontaneous transfer of intrinsic electrons from Cd0.9Zn0.1S to C-MoO2 in the dark,
establishing an internal electric field at the C-MoO2/Cd0.9Zn0.1S interface. Under visible
light irradiation, the C-MoO2/Cd0.9Zn0.1S composite exhibited significantly enhanced
hydrogen evolution activity, achieving a 6.3-fold improvement compared to pristine
Cd0.9Zn0.1S. PL, TRPL, and electrochemical measurements collectively demonstrated that
the incorporation of C-MoO2 effectively suppressed the recombination of photogenerated
electrons in Cd0.9Zn0.1S. The outstanding photocatalytic performance and improved charge More >
