| Outline of Final Research Achievements |
The activity of a Cu0.8Ag0.2GaS2 photocathode for H2O and CO2 reduction was drastically improved by comodification with Ag and ZnS. Additionally, the conductive organic polymer necking that formed between the metal sulfide photocatalyst particles and a substrate improved the photoelectrochemical performances of the metal sulfide photocathodes. Photoelectrochemical cells for artificial photosynthetic H2O and CO2 reduction to form syngas in an aqueous solution under simulated sunlight have been successfully developed by combining the photocathode and a CoO-loaded BiVO4 photoanode.
