Using FeSO4 x 7H2O and H2O2 as raw materials, a facile route to selective synthesis of alpha-FeOOH and alpha-Fe2O3 nanorods was developed by adjusting the reaction temperature in hydrothermal synthesis. Without undergoing calcinations, the obtained alpha-FeOOH nanorods (at 150 degrees C) and alpha-Fe2O3 nanorods (at 200 degrees C) possess high morphological yield (> 95%). The influences of synthesis conditions such as H2O2, hydrothermal temperature and hydrothermal time were investigated. The formation process of alpha-FeOOH and alpha-Fe2O3 nanorods was discussed in detail, and a possible temperature-controlled selective synthesis mechanism was proposed.
以FeSO₄·7H₂O和H₂O₂为原料，通过水热合成中调节反应温度，开发了一种选择性合成α-FeOOH和α-Fe₂O₃纳米棒的简便方法。无需煅烧，所制备的α-FeOOH纳米棒（在150℃下）和α-Fe₂O₃纳米棒（在200℃下）具有较高的形貌产率（>95%）。研究了H₂O₂、水热温度和水热时间等合成条件的影响。详细讨论了α-FeOOH和α-Fe₂O₃纳米棒的形成过程，并提出了一种可能的温度控制选择性合成机制。
