首次利用离子液体(IL)作为铁源和磷源制备磷化铁。以IL三己基(十四烷基)四氯高铁酸([P(C 6 H 13 ) 3 C 14 H 29 ][FeCl 4 ])和碳纳米管(CNT)为前驱体,原位制备Fe 2 P (IL6) /碳纳米管。该材料对析氢反应具有良好的催化活性和稳定性,包括低起始过电势(75 mV)和塔菲尔斜率(68 mV dec -1 )。此外,该催化剂在115和150mV的过电势下分别表现出10和20mA cm -2的电流密度。还研究了使用[P(C 6 H 13 ) 3 C 14 H 29 ][FeCl 4 ]的磷化过程。所有实验结果表明,使用该IL可以在CNT上原位形成Fe 2 P,并且CNT有助于Fe 2 P纳米粒子的形成并提高导电性。这种基于 IL 的原位制备策略简单且环保,不需要添加其他试剂。 该方法在其他电化学研究中具有广阔的应用前景。

A series of ionic liquids containing different paramagnetic anions have been prepared and all show paramagnetic behavior with potential applications for magnetic and electrochromic switching as well as novel magnetic transport; also, the tetraalkylphosphonium-based ionic liquids reveal anomalous magnetic behavior.
