“…The diffusion coefficient of ARSNa at room temperature was determined from the Levich equation to be 6.2×10 −7 cm 2 s −1 (Figure S5a) . This value is close to those previously reported in acidic (2.14 and 1.58×10 −6 cm 2 s −1 ) [9,11b] and neutral media (2.88×10 −6 cm 2 s −1 ) [11b] . The electron transfer rate constant k s was estimated as 1.2×10 −3 cm s −1 from the Tafel plot (Figure S5b,c) [12] .…”

The performance of a redox compound in redox flow batteries (RFB) highly depends on the electrolytic medium and operating conditions. It is exemplified in this work with the commercially available and relatively low-cost dye 3,4-dihydroxy-9,10-anthraquinone-2-sulfonic acid (ARS), which was used as negolyte in basic medium. At high pH, the ARS behavior revealed interesting features for RFB applications, such as a low halfwave potential of À 0.99 V (vs Ag/AgCl), negatively shifted by phenolate groups, and an improved solubility compared with acidic medium depending on the nature of the cations. For the highly soluble ARS potassium salt (ARSK), a maximum power density of 117 mW cm À 2 and a demonstrated energy density of 20 Wh L À 1 were obtained with K 4 [Fe(CN) 6 ] as posolyte. The capacity slightly decreased during cycling, reaching 90 % after 325 cycles. A long cycling of ARS sodium salt (ARSNa) over 11 operating months was demonstrated in this work. A slow chemical degradation was highlighted giving rise to the formation of 3-hydroxy-9,10-anthraquinone-2-sulfonic acid (HAQS) as the main degradation product due to hydrodeoxygenation reaction. Interestingly, this compound exhibited high performance in RFB and a good stability with a loss of capacity of 0.29 % per day.

“…Although the ARS used in this investigation was produced synthetically, producing alizarin from plants is still a viable option, especially when considering the environmental benefits compared to the synthetic route. [20] Other anthraquinone derivatives have also been used in supercapacitors, [21] organic flowbatteries [22,23] as well as in metal ion batteries. [18,19] Since alizarin possesses both carbonyl and hydroxyl groups in its equilibrium state, the molecule can be either reversibly oxidized or reduced.…”

availability of renewable energy. While batteries can store large amount of energy per unit mass/volume (energy density), supercapacitors can typically be charged and discharged at relatively higher rates and possess generally a longer lifetime. Lithium-ion batteries (LIB) have one of the highest energy densities among commercial batteries and are already used in grid-scale electrical energy storage systems. However, LIB systems are typically expensive to manufacture, and the restrictions and precautions that apply to largescale LIBs with respect to transportation and operation are rigorous, due to that battery failure may cause fires and explosions. Besides cost, safety, and lifetime, another important aspect, which is less frequently discussed, is the environmental impact of different energy storage technologies; recycling is particularly challenging for LIB technology. Battery technologies rely on a vast array of metals that are extracted through rare earth mining and bottlenecks in the supply of these materials is a challenge. This (surface) mining industry consumes large amounts of energy in itself, leaves our planet with scars and produces great amounts of waste that is utterly difficult and costly to clean. Many of these metals are also toxic and may cause many problems if leakage of the battery components occurs due to improper disposal. Finally, there are no efficient large-scale recycling procedures for many battery technologies (e.g., LIB) as of today. [1] In the search for green energy storage solutions, more and more attention has been focused on organic materials such as using conductive polymers and redox-active molecules. [2] Organic materials can be manufactured and processed at high volumes, at low temperatures, thus enabling a cost-effective production process of energy storage technologies. Many organic materials are flexible and can be dissolved in aqueous or organic solvents, which allows for high-throughput manufacturing techniques, such as using printing, coating, and lamination. Several conductive polymers, such as polythiophene, polypyrrole, polyaniline, and poly(3,4-ethylenedioxythiophene) (PEDOT), have been widely studied and explored as the electrode materials in batteries and supercapacitors. [3] PEDOT is considered to be one of the most chemically, electrochemically, and mechanically stable conductive polymers, especially when combined with the polymeric counter-ion poly(styrene sulfonate) (PSS). Also, PEDOT:PSS has a high mixed ionic and electronic conductivity, but exhibits a relatively low specific capacitance of about 30-40 F g −1 . [4] A supercapacitor made from organic and nature-based materials, such as conductive polymers (PEDOT:PSS), nanocellulose, and an the organic dye molecule (alizarin), is demonstrated. The dye molecule, which historically was extracted from the roots of the plant rubia tinctorum, is here responsible for the improvement in energy storage capacity, while the conductive polymer provides bulk charge transport within the composite electrode.

An Electrochemical Approach to As(V) Determination via an Interaction with Alizarin Red S in Aqueous Medium

Electrochemically inactive As(V) was detected by estimating the interactions between Alizarin Red S (ARS) and ions in aqueous medium. From the cyclic voltammetry, it was confirmed that the addition of As(V) reduces the diffusion coefficient of the ARS molecule towards the electrode surface. The experimental results revealed that the diffusion coefficient of ARS was 1.476 × 10 −5 cm 2 /s which decreased to 1.02 × 10 −5 cm 2 /s in the presence of ions in the solution. Measurements of electrochemical impedance spectroscopy (EIS) were also carried out, and an upward pattern of charge transfer resistance (R ct ) was found with an increase in As(V) concentration. The EIS technique gave a linear relationship in terms of R ct vs. As(V) concentration. Hence, it was concluded that this technique could be utilized in the electrochemical detection of As(V). The developed method for the detection of As(V) has exhibited excellent sensitivity (74 Ω/μM), low detection limit (14.2 ± 0.1 ppb at S/N of 3), and remarkable repeatability.
