Coupling of Crumpled-Type Novel MoS₂ with CeO₂ Nanoparticles: A Noble-Metal-Free p-n Heterojunction Composite for Visible Light Photocatalytic H₂ Production.

ABSTRACT: In terms of solar hydrogen production, semiconductor-based photocatalysts via p-n heterojunctions play a key role in enhancing future hydrogen reservoir. The present work focuses on the successful synthesis and characterization of a novel p-MoS₂/n-CeO₂ heterojunction photocatalyst for excellent performance toward solar hydrogen production. The synthesis involves a simple in situ hydrothermal process by varying the wt % of MoS₂. The various characterization techniques support the uniform distribution of CeO₂ on the surface of crumpled MoS₂ nanosheets, and the formation of p-n heterojunction is further confirmed by transmission electron microscopy and Mott-Schottky analysis. Throughout the experiment, it is demonstrated that 2 wt % MoS
