Water Splitting and CO 2 Reduction using Metal Oxide and Sulfide Photocatalyst Materials

Artificial photosynthesis is expected to solve energy, environment, and resources issues. Water splitting and CO2 reduction of artificial photosynthesis have extensively been studied using photocatalyst materials. Various metal oxide and sulfide photocatalysts developed by the author’s original strategies are introduced. These heterogeneous photocatalyst materials have been applied to a single particle system, Z-schematic system, and photoelectrochemical systems for water splitting and CO2 reduction using water as an electron donor.
