Details	Photocatalytic water splitting is an artificial photosynthetic reaction in which solar energy is converted to chemical energy. Many metal sulfides efficiently produce hydrogen from water under visible light irradiation. However, the metal sulfides was considered to be unfavorable for water splitting, because they are not stable under photoirradiation (photocorrosion). In the present study, we developed water splitting systems utilizing metal sulfide photocatalyst and photoelectordes upon combining with suitable photoatalysts for oxygen evolution.
