Carbon-catalyzed dye-sensitization for solar hydrogen production.

Highlights: [•] Carbon materials successfully catalyzed Eosin Y-sensitized H2 production under solar light. [•] H2 production and photocurrent generations were 9- and 4-fold enhanced by CNT, respectively. [•] Pt-loading onto carbon materials further enhanced the H2 production by 10 times. [•] Eosin Y underwent spectral shifts because of de-bromination. [ABSTRACT FROM AUTHOR]
