| 摘 要： | 利用一种新的原位水解沉积方法，以在高湿度空气中老化的甲醇中作为溶剂，通过乙醇钽水解而成前驱体微球颗粒沉积，制备出了高效的Ta3N5微球光电极，其1.6 V（vs RHE）电极电位下的光电流值达到了6.6 mA·cm-2。相反地，在新鲜的甲醇溶液中没有钽前驱体微球颗粒沉积。这表明甲醇中水的含量对Ta3N5微球光电极的形成十分重要。另外，本制备方法也能方便地在其他透明导电衬底上制备出Ta3N5。

| Abstract: | A new in situ hydrolysis deposition method was used to prepare a Ta3N5 microsphere photoanode, which indicates a high photocurrent of 6.6 mA·cm-2 at 1.6 V vs RHE. Microsphere precursor films are formed by hydrolysis of Ta(OEt)5 and subsequent deposition on substrates, which is achieved by aging methanol solvent in air with high humidity. In contrast, no precursor films were obtained on substrates with fresh methanol. The results suggest that water in solvent is very essential to in situ depositing Ta3N5 photoanode. In addition, the facile method can be used to deposit Ta3N5 on other transparent conducting substrates. |
