介绍了一种通过两步阳极氧化方法制备紧密结合的Ta3N5纳米管阵列(NTA)光阳极的方法，该方法提高了Ta3N5层与衬底之间的电子传导性。得到的紧密结合的Ta3N5 NTA光阳极具有良好的光电化学性能，与可逆氢电极相比，在1.6V时的最佳光电流可达5.3 mA cm(-2)。该方法为解决一维半导体光阳极的附着力问题提供了一种有效的策略。
This paper describes an approach to synthesize a tightly adhered Ta3N5 nanotube array (NTA) photoanode with enhanced electron conductivity between the Ta3N5 layer and the substrate via a two-step anodization method. The obtained tightly adhered Ta3N5 NTA photoanode exhibits excellent photoelectrochemical properties with an optimal photocurrent up to 5.3 mA cm(-2) at 1.6 V vs. the reversible hydrogen electrode. This approach provides an effective strategy to address the adhesion issue of one dimensional semiconductor photoanodes.
