Hierarchical zeolites containing embedded Cd 0.2 Zn 0.8 S as a photocatalyst for hydrogen production from seawater.

Uncovering an efficient and stable photocatalytic system for seawater splitting is a highly desirable but challenging goal. Herein, Cd 0.2 Zn 0.8 S@Silicalite-1 (CZS@S-1) composites, in which CZS is embedded in the hierarchical zeolite S-1, were prepared and show remarkably high activity, stability and salt resistance in seawater.
