Abstract: A new hybrid photoelectrochemical photoanode is developed to generate H <subscript>2</subscript> from water. The anode is composed of a TiO <subscript>2</subscript> 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 <superscript>-2</superscript> in a solar-cell-driven photoelectrochemical system using near-infrared QDs is obtained.
