Abstract

A versatile biotemplate method is developed for the fabrication of porous carbon tubes embedded with CeO₂ quantum dots (QDs) as a high-efficiency photocatalyst by using bean sprouts. Interestingly, this novelly hierarchical three-dimensional porous CeO₂ QDs/carbon exhibits an enhanced hydrogen evolution feature from water splitting under xenon lamp irradiation. The excellent performance of the said material is attributed to the synergistic effect between CeO₂ QDs and carbon films, inlaid ceria QDs structure, biomorphic porous architecture, a high specific surface area, and abundant oxygen vacancies. This encouraging result reveals a reproducible approach for processing metal oxide QDs/carbon photocatalysts with high reactivity and shows the possibility for energy application.
