采用电化学阳极氧化法在钛片上制备了高度有序的TiO 2纳米管阵列。Pt/TNTAs/Pt纳米粒子可以均匀地分布在TiO 2纳米管的一侧（Pt/TNTAs）或两侧（Pt/TNTAs/Pt）。Pt/TNTAs是一种单面沉积Pt的TNTAs，可直接用于水的裂解而无需对电极。在0.5M Na 2SO 4和0.5M乙二醇的混合溶液中，无偏压时的析氢速率可达120 μmol h-1cm-2，是纯TNTAs的6倍。与传统的三电极系统相比，这种单面Pt沉积的TNTA是一种更简单和有效的水裂解系统。同时，对薄膜的光电转换机理进行了详细的研究。
Highly-ordered TiO2nanotube arrays (TNTAs) were fabricated on Ti sheets by electrochemical anodization. Uniform Pt nanoparticles with an average diameter of 3 nm could be successfully located on the TiO2nanotubes on only one side (Pt/TNTAs) or both sides of the Ti sheet (Pt/TNTAs/Pt). Pt/TNTAs, the single-sided Pt deposited TNTAs, could be directly used to split water without a counter electrode. The hydrogen evolution rate can reach 120 μmol h−1cm−2in a mixed solution of 0.5 M Na2SO4and 0.5 M ethylene glycol without any applied bias, which is six times of that by the pure TNTAs. In comparison to the traditional three electrode system, this single-sided Pt deposited TNTAs is a much more simple and efficient water splitting system. Meanwhile, the photoelectrical conversion mechanism has been investigated in detail.
