| 摘 要： | 高性能催化剂的开发和利用是能源领域的研究热点,其中制备具有高活性面积的一维纳米催化剂是目前的难点.本研究以金属有机框架(MOF)复合纤维为前驱体,通过热处理-磷化过程制备了具有氧析出(OER)和氢析出(HER)双功能特性的CoP纳米纤维.该MOF衍生策略也可以用来制备其他一维纳米材料,如Co3O4纳米纤维、Co/C纤维和CoP/C复合纤维.研究表明,CoP纳米纤维的直径约100 nm,长度可达几微米,具有较高的活性面积.通过Cu掺杂改性可以提高CoP纳米纤维的催化活性,碱性条件下测得其对OER和HER的过电位分别为330和170 mV,可与商业的贵金属催化剂相媲美.该工作也为一维双功能电极催化剂的制备及功能化提供了研究基础.
