Conclusion
In summary, an efficient photocatalyst based on
Ni(OH)2@CdSe/CdS QDs has been reported for its activity
toward acceptorless dehydrogenation of hydrogen-rich
N-heterocycles. Ni(OH)2@CdSe/CdS QDs are proved to be highly
active for the photocatalytic dehydrogenation of THQ, iso-THQ,
indoline, and their derivatives, with as high as 93% yield of
dehydrogenation products and 100% yield of released hydrogen.
The admirable activity of the photocatalytic system can be
attributed to the heterojunction structure of the CdSe/CdS QDs
and the suitable redox potential of the Ni(OH)2 co-catalysts. As a
consequence, the combination of these photocatalysts raises
the possibility that this system might be applied to hydrogen
release at ambient temperature. The present research provides a
powerful complement or potential competitor to the thermally
promoted dehydrogenation systems, especially suitable for the
application in a sunny environment.
