Near‐Infrared Colloidal Quantum Dots for Efficient and Durable Photoelectrochemical Solar‐Driven Hydrogen Production

Abstract

<b>A new hybrid photoelectrochemical photoanode</b> 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.
