“…The N 1 s XPS spectra of the doped graphite felts are shown in Figure 2b,c. Three deconvoluted peaks can be observed, indicating the presence of pyridinic N (398.1‐398.8 eV), amino N (399.3 eV), pyrrolic N (398.8‐401 eV), graphitic N (401.1‐401.8 eV), and N‐oxides of pyridinic N (402.6 eV) 39‐41 . Figure 2d presents doublet peaks at 190.0 and 193.0 eV, which correspond to BC 3 and BC 2 O, respectively 42 .…”

In this article, a graphite felt electrode was modified by NS double‐element and NB double‐element codoping. The surface morphology, crystal structure, element content, and surface chemical state of the modified electrode were characterized by scanning electron microscopy, X‐ray powder diffraction (XRD), Raman spectroscopy, and X‐ray photoelectron spectroscopy. The electrochemical performance of the modified electrode was evaluated by cyclic voltammetry, electrochemical impedance spectra, and a single cell. The results show that nitrogen (N) and boron (B) double‐element codoping can enhance the catalytic activity of graphite felt and create abundant defect sites, which increases the electrocatalytic activity by approximately a factor of 2. The reason why the doped graphite felt can obtain higher electrocatalytic activity may be related to the synergy between N and B atoms, especially the synergy between pyridine‐N and BC3, and the resistance of the first charge transfer reaction of 1,8‐dihydroxyanthraquinone on the doped graphite felt electrode is then reduced.

Redox flow batteries are a hot topic for both scientists and engineers. Use of carbon electrodes is ubiquitous, and their surface modification is one of the key issues that stands in the way of commercialization breakthroughs. In this critical analysis of the representative literature, we offer readers a necessary interdisciplinary view of the challenges and opportunities for researchers in the fields of carbon surface chemistry, batteries, fuel cells and electrocatalysis on solid surfaces. Though focused on carbon electrode materials for the vanadium redox flow battery, we provide experimental and quantum chemical insights applicable to many established and emerging electrochemical energy conversion technologies. Given the current state of the art, considerable effort is spent addressing the controversial role of oxygen functional groups in the electrocatalytic activity of graphene-based electrodes.

“…Depending on additives in the process, the morphology can be influenced to result into 2D structures (rGO [60] or 2D nano sheets [57]) or highly porous carbon structures as a result from alkali inducing surface etching, resulting in outstanding high surface areas (reported up to 1857 [53], 1901 [54], or 2085 m 2 g −1 [55]). Self-doping in case of chitin-based biomass (shrimp [52], fish scales [57]) can be observed, or induced by additives to the carbonization leading to doping with nitrogen [35,58] or oxygen [55] or iron [59]. (b) The AC can be used to decorate the fiber surface, enhancing the electrocatalytic properties, determined by CV or EIS.…”

“…Additionally, the use of additives, such as amines, urea, phosphoric acid, or for example, iron containing additives can lead to the introduction of heteroatoms to boost the performance of the biomass-derived carbon electrodes [33]. These strategies lead to an increase of charge accumulation at the interface electrode/electrolyte, which in turns promotes the adsorption of positive and negative charges to the surface of the electrode [34,35].…”

“…A similar approach for N-doping was reported by using ammonium oxalate ((NH 4 ) 2 C 2 O 4 ) as a nitrogen source and persimmons, an edible fruit, as biomass [35]. The biomass was used to produce a preliminary carbon (PC) via hydrothermal treatment, followed by carbonization at 750 • C, as schematically shown in figure 3(a).…”

The development of alternative energy storage technologies is key to advance renewable energy resources. Among them, redox flow batteries (RFBs) have been identified to be one of the most promising technologies in the field of stationary batteries. The carbon-based electrodes in these batteries are a crucial component and play an important part in achieving high efficiency and performance. A further leap into this direction is the design of fossil-free materials by incorporating sustainable alternative resources as the carbon component in the processing of the electrodes. The use of biomass as carbon precursor for electrode applications has also been a focus of research for other energy storage devices and in the case of RFBs, it has become an emergent topic in recent years. This short review presents the recent advances in the design of biomass-derived carbon materials as electrodes in RFBs, strategies to enhance their electrocatalytic properties, challenges, and future outlook in the design of sustainable electrode materials.
