摘要: 高熵合金(HEAs)被认为是开发低Pt含量氧电催化剂的一种有效途径。为此，本文报道了一种以炭黑插层MXene作为杂化载体耦合Pt基五元HEAs的催化剂(PtPdAuNiCu/MC3)。X-射线衍射测试表明，催化剂中的五元高熵合金纳米颗粒为面心立方结构。在三电极体系测试中，表现出优于商业Pt/C的氧还原性能(Eonset = 1.011 V/E1/2 = 0.886 V)和接近RuO2的氧析出性能(Ej=10 = 1.824 V)。本研究可为今后基于MXene的其他电化学催化体系的开发提供有价值的参考。
Abstract: High entropy alloy (HEAs) is considered to be an effective way to develop oxygen electrocatalysts with low Pt content. For this reason, a carbon black intercalated MXene was used as a hybrid support to couple the five-component HEAs (PtPdAuNiCu/MC3) headed by Pt. X-ray diffraction results show that this five-element HEAs nanoparticleshave a face centered cubic structure. In a three-electrode testing system, the oxygen reduction performance (Eonset = 1.011 V/E1/2 = 0.886 V) is better than those of commercial Pt/C and the oxygen evolution performance (Ej=10 = 1.824 V) is close to those of commercial RuO2, respectively. This study would provide a valuable reference for the development of other electrocatalysts based on MXene in the future.
