Hydrogen production from water in the presence of S 2− and SO 3 2− ions in PEC cells using a PbS/mp‐TiO 2 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.
