A combinatorial approach has been carried out to systematically investigate visible-light responsiveness of Fe-Ti-M (M: various metal elements) oxides for photoelectrochemical water splitting. Among the 25 elements tested, strontium was the most effective. A ternary metal oxide with the composition Fe(86.1)Ti(9.6)Sr(4.3)O(x) has been identified as a new lead structure for a visible-light responsive, n-type semiconductor. We have conducted various kinds of characterization of the Fe-Ti-Sr oxide semiconductor and discussed the reason why Sr in the Fe-Ti oxide gave the highest photocurrent.
已采用组合方法系统研究了铁钛 - M（M：各种金属元素）氧化物对光电化学水分解的可见光响应性。在测试的25种元素中，锶最为有效。已确定组成为Fe(86.1)Ti(9.6)Sr(4.3)O(x)的三元金属氧化物是一种用于可见光响应型n型半导体的新型铅结构。我们对铁钛锶氧化物半导体进行了各种表征，并讨论了铁钛氧化物中的锶产生最高光电流的原因。
