通过水热反应制备了具有选择性暴露面的矩形WO3颗粒，并在Fe3+电子受体存在下用作析氧光催化剂。即使在 Fe3+ 减少和 Fe2+ 浓度增加的情况下，所制备的 WO3 光催化剂仍表现出比其他商业催化剂更高的析氧速率和选择性，这当然归因于暴露面的独特吸附性能。
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.
