Na0.5Bi0.5TiO3 (BG 3.1 eV) with a valence band formed by Bi(iii) was found as a new photocatalyst for solar water splitting. The water splitting activity of highly crystalline Na0.5Bi0.5TiO3 synthesized by a flux method was much higher than that of the samples synthesized by a solid-state reaction. The optimized RhCr2Ox(0.1 mol%)/Na0.5Bi0.5TiO3/CoOOH(0.02 mol%) gave a 5.1% apparent quantum yield at 350 nm and split water even under simulated sunlight irradiation with a 0.05% solar to hydrogen energy conversion efficiency. We have successfully achieved solar water splitting using a one-step photoexcitation type photocatalyst valence-band-controlled with Bi(iii).
发现由Bi(iii)形成价带的Na0.5Bi0.5TiO3（带隙3.1电子伏特）是一种用于太阳能水分解的新型光催化剂。通过助熔剂法合成的高结晶度Na0.5Bi0.5TiO3的水分解活性远高于通过固态反应合成的样品。优化后的RhCr2Ox(0.1 mol%)/Na0.5Bi0.5TiO3/CoOOH(0.02 mol%)在350纳米处的表观量子产率为5.1%，甚至在模拟太阳光照射下也能分解水，太阳能到氢能的能量转换效率为0.05%。我们已经成功地使用由Bi(iii)控制价带的一步光激发型光催化剂实现了太阳能水分解。
