From: Efficient and stable n-type sulfide overall water splitting with separated hydrogen production
Stability of H2 and O2 production over a uncoated HEP (Pt@CrOx/Co3O4/CdS) and OEP (Ir/IrO2/BiVO4-Co), b TiO2-coated HEP with uncoated OEP, and c TiO2-coated HEP with SiO2-coated OEP. d Catalyst deactivation over four reaction cycles. e Long-term cycling stability over TiO2-coated HEP and SiO2-coated OEP. f Apparent quantum yields of Z-scheme system using TiO2-coated HEP and SiO2-coated OEP, together with DRS curves of uncoated CdS and BiVO4-Co. Error bars indicate the standard deviations. Source data are provided as a Source data file.
