Z-scheme overall water splitting on photocatalyst sheet mediated by carbon nanotubes using oxysulfide photocatalyst responsive to long wavelengths.

ABSTRACT: Narrow-bandgap photocatalysts enable broad visible-light absorption and, theoretically, should provide high solar-to-hydrogen (STH) energy conversion efficiencies. However, the actual performance of such materials is highly dependent on the design and fabrication of the water-splitting system. In this study, photocatalyst sheets were constructed using Ga-doped La₅Ti₂Cu_0.9Ag_0.1O₇S₅ (Ga-LTCA, with absorption at λ < 700 nm) as the hydrogen evolution photocatalyst together with BiVO₄ (BVO) as the oxygen evolution photocatalyst, and carbon nanotubes (CNTs) as the electron mediator, employing a cost-effective filtration process. The three components were tightly integrated on a filter paper substrate, allowing th
