Rectangular WO3 particles with selectively exposed faces were prepared via hydrothermal reaction and employed as O2-evolving photocatalyst in the presence of Fe3+ electron acceptor. The prepared WO3 photocatalyst showed a higher rate and selectivity for O2 evolution than other commercial ones even with decreased Fe3+ and increased Fe2+ concentrations, certainly attributable to the unique adsorption property of the exposed faces.
