A photoelectrode of single-crystal rutile TiO(2) pillars with well-developed facets shows a 2.5 times higher capability of water splitting at 0.3 V than a conventional anatase TiO(2) nanotube array electrode. The improvement is attributed to the synergistic effects of the high crystallinity of single-crystal rutile pillars, the exposed high-energy {011} and {111} as the reactive facets of water oxidation reaction and the extended light absorption range by ca. 23 nm.
单晶金红石 TiO(2) 柱具有发达的晶面的光电极为 0.3 V 下的水分解能力比传统锐钛矿 TiO(2) 纳米管阵列电极高 2.5 倍。这种改善归因于单晶金红石柱的高结晶度、暴露的高能 {011} 和 {111} 作为水氧化反应的反应面以及通过约 23nm 扩展的光吸收范围的协同效应。
