摘要
采用一锅水热法在碳布上制备了一种MoS2@CoFe-MOF电催化剂。结果表明,MoS2@CoFe-MOF 具有优异的电催化活性。它能分别用 220 mV 和 405 mV 的过电位驱动 10 mA cm-2 和 50 mA cm-2。结果表明,MoS2@CoFe-MOF 电极在 48000 秒结束时表现出极佳的稳定性,并且具有最高的电化学活性比表面积和最低的电荷转移电阻。这项研究为能源化学领域利用非贵重过渡金属硫化物和双金属 MOF 组成的电催化剂电解水制氢提出了一种可行的方法。
MoS2@CoFe-MOF catalysts achieved by one-pot hydrothermal synthesis enhanced electronic interactions between MoS2 nanoflowers and a bimetallic MOF for efficient oxygen evolution†
A kind of MoS2@CoFe-MOF electrocatalyst was prepared on carbon cloth by a one-pot hydrothermal method. Excellent electrocatalytic activity of MoS2@CoFe-MOF is demonstrated, and the catalyst has overpotentials of 220 mV and 405 mV at 10 mA cm−2 and 50 mA cm−2, respectively. It is found that the MoS2@CoFe-MOF electrode exhibits excellent stability at the end of operation for 48 000 s, and it has the highest electrochemically active specific surface area and the lowest charge transfer resistance. This work proposes a promising approach in energy chemistry for hydrogen production by electrolysis of water using electrocatalysts composed of non precious transition metal sulfides and bimetallic MOFs.
