- 摘要:
- 为获得活性位点丰富、导电性好与活性高的碲化铜（Cu 7Te 4）催化剂，通过对静电纺丝所制备的前驱体薄膜进行碳化处理得到Cu 7Te 4纳米颗粒与碳纳米纤维复合的材料Cu 7Te 4@CNFs；利用SEM、TEM、XRD、XPS等表征复合纤维材料的形貌和结构组成，并通过电化学测试技术分析复合材料的电催化析氢（HER）、肼氧化（HzOR）及HzOR辅助全水解性能。结果表明：Cu 7Te 4@CNFs具有丰富的催化活性位点，在碱性电解液中分别仅需394 mV的过电位和544 mV（ vs. RHE）的工作电位，能产生10 mA/cm 2的HER和HzOR催化电流密度，表现出良好的电催化性能；在400 mV的过电位和550 mV（ vs. RHE）的工作电位下恒电位电解12 h，催化电流密度没有明显衰减，表现良好的电催化稳定性；HzOR辅助全水解仅需1.23 V的工作电压就能达到10 mA/cm 2的催化电流密度，相较于传统全水解体系有效降低了1.96 V的工作电压。该研究为高活性铜基双功能催化剂的设计合成以及在低能耗电解水制氢的研究策略方面提供了新的研究思路。
