摘要

由基于corrole的配体衍生的第一行过渡金属络合物被认为是析氢反应（HER）的有效催化剂。众所周知，它们可以通过降低水分解过程中的能垒来提高氢气的生产速率。本文报道了一种在corrole上具有胺官能团的铜corrole配合物（CuN2CA）的合成和表征。将该复合物固定在还原的氧化石墨烯（CuN2CA-rGO）上，该氧化石墨烯对析氢反应（HER）表现出优异的电催化活性，起始电位为-0.57V，与NHE相比显著降低。当与还原的氧化烯（rGO）结合时，corrole复合物的效率显著提高。

Copper corrole immobilized onto reduced graphene oxide: An efficient electrocatalyst for hydrogen evolution reaction

First-row transition metal complexes derived from corrole-based ligands are considered efficient catalysts for hydrogen evolution reaction (HER). They are known to enhance the rate of hydrogen production by lowering the energy barrier in the water-splitting process. Here, the synthesis and characterization of a copper corrole complex (CuN2CA) having amine functionality on corrole has been reported. This complex is immobilized onto reduced graphene oxide (CuN2CA-rGO) that exhibited excellent electrocatalytic activity towards hydrogen evolution reaction (HER) with a significantly lower onset potential of -0.57 V vs. NHE efficiency of the corrole complex has significantly been improved when combined with reduced graphene oxide (rGO).
