We report the template-free synthesis of Ta3N5 nanorod array films grown on Ta foil by a combination of a vapor-phase hydrothermal process and subsequent nitriding. The Ta3N5 nanorod array film modified with Co(OH)x when used as a photoanode in a photoelectrochemical cell for water splitting yields a stable photocurrent density of 2.8 mA cm(-2) at 1.23 VRHE under AM 1.5G simulated sunlight. The incident photon-to-current conversion efficiency at 480 nm is determined to be 37.8%.
我们报告了一种通过气相水热工艺和随后的氮化相结合，在 Ta 箔上无模板合成 Ta3N5 纳米棒阵列薄膜的方法。将 Co(OH)x 修饰的 Ta3N5 纳米棒阵列薄膜用作光电化学池中的光阳极进行水分解时，在 AM 1.5G 模拟太阳光下，1.23 VRHE 时可稳定产生 2.8 mA cm(-2) 的光电流密度。在 480nm 处的入射光子到电流的转换效率被确定为 37.8%。
