Abstract

A new hybrid photoelectrochemical photoanode is developed to generate H₂ from water. The anode is composed of a TiO₂ mesoporous frame functionalized by colloidal core@shell quantum dots (QDs) followed by CdS and ZnS capping layers. Saturated photocurrent density as high as 11.2 mA cm^-2 in a solar-cell-driven photoelectrochemical system using near-infrared QDs is obtained.

Keywords: core@shell quantum dots; hydrogen generation; near‐infrared; water‐splitting.
