将Ta金属片与NH 4Cl粉末混合，经真空密封煅烧，制备出棒状Ta 3 N5薄膜。光电化学水氧化实验结果表明，在1.23 V（vs. RHE）下，阳极光电流为3.2 mA cm-2，法拉第效率为1。
A rod-like Ta3N5 thin film was synthesized by calcining a vacuum-sealed mixture of Ta metal plates and NH4Cl powder. Photoelectrochemical water oxidation results showed that an anodic photocurrent of 3.2 mA cm-2 at 1.23 V (vs. RHE) with a faradaic efficiency of unity for O2 evolution could be achieved by employing the as-prepared Ta3N5/Ta as a photoanode.
