Tungsten Oxide-Based Z-Scheme for Visible Light-Driven Hydrogen Production from Water Splitting.

ABSTRACT: The stoichiometric water splitting using a solar-driven Z-scheme approach is an emerging field of interest to address the increasing renewable energy demand and environmental concerns. So far, the reported Z-scheme must comprise two populations of photocatalysts. In the present work, only tungsten oxides are used to construct a robust Z-scheme system for complete visible-driven water splitting in both neutral and alkaline solutions, where sodium tungsten oxide bronze (Na_0.56WO_3-x) is used as a H₂ evolution photocatalyst and two-dimensional (2D) tungsten trioxide (WO₃) nanosheets as an O₂ evolution photocatalyst. This system efficiently produces H₂ (14 μmol h^-1) and O₂ (6.9 μmol h^-1) at
