摘要

本文报道了阳极氧化对氧化还原活性分子茜素在正极和负极上的可逆性和电化学活性的增强作用。茜素是一种双功能的植物基蒽醌氧化还原物质,在正电位下表现出不可逆性(相对于Ag/AgCl)。结果表明,碳纸的阳极氧化增加了碳纸的表面积,引入了官能团,从而提高了碳纸在正电位处的可逆性。为了证明我们的技术的适用性,我们将改性电极用于对称的水性有机氧化还原液流电池,与原始碳电极相比,在容量保持和库仑效率方面有显着改善。

On the Reversibility of Sustainable Symmetric Aqueous Organic Redox Flow Batteries

On the Reversibility of Sustainable Symmetric Aqueous Organic Redox Flow Batteries

Herein, the effect of electrode anodization on the enhancement of the reversibility and the electrochemical activity of the redox-active molecule alizarin in both positive and negative electrodes is reported. Alizarin is a bifunctional plant-based anthraquinone redox species that exhibits irreversibility at positive potential (versus Ag/AgCl). The results show that the anodization of carbon paper increases surface area and introduces functional groups, which in turn promotes reversibility at the positive potential. To demonstrate the applicability of our technique, the modified electrodes are used in a symmetric aqueous organic redox flow battery, showing a significant improvement in capacity retention and Coulombic efficiency compared to pristine carbon electrodes.
