PbS Quantum Dot-Sensitized Photoelectrochemical Cell for Hydrogen Production from Water under Illumination of Simulated Sunlight

Hydrogen production from water in the presence of S2− and SO32− ions in PEC cells using a PbS/mp‐TiO2 photoanode under illumination of simulated sunlight is reported (see figure). A total conversion efficiency of 1.15 % is achieved with a hydrogen production rate of 5.2 mL h−1, demonstrating that th...

Description
Summary:Hydrogen production from water in the presence of S2− and SO32− ions in PEC cells using a PbS/mp‐TiO2 photoanode under illumination of simulated sunlight is reported (see figure). A total conversion efficiency of 1.15 % is achieved with a hydrogen production rate of 5.2 mL h−1, demonstrating that the PbS QD–SPEC cell can efficiently convert solar energy to hydrogen energy.
