In(OH)(3) nanostructures with controllable shapes were successfully synthesized using indium nitrate as an indium source by one-step electrodeposition process. The influences of the reaction temperature, time, indium nitrate concentration, and the applied potential on the morphology of the obtained products were discussed in detail. The results revealed that the growth behavior of In(OH)(3) was mainly determined by the indium nitrate concentration and applied potential, and well-defined ellipsoids, cubes, and rods could be prepared under suitable conditions. Their possible growth mechanisms as well as photocatalytic applications were addressed. Furthermore, In(2)O(3) nanostructures were obtained from In(OH)(3) upon heating, while size and morphology can be maintained during this process.
采用硝酸铟作为铟源，通过一步电沉积法成功合成了具有可控形状的 In(OH)(3)纳米结构。详细讨论了反应温度、时间、硝酸铟浓度和外加电位对产物形貌的影响。结果表明，In(OH)(3)的生长行为主要由硝酸铟浓度和外加电位决定，在适当的条件下可以制备出具有规则的椭圆形、立方体和棒状结构。讨论了它们可能的生长机制以及光催化应用。此外，通过加热 In(OH)(3)可以得到 In(2)O(3)纳米结构，并且在这个过程中可以保持其尺寸和形态。
