“…BiFEs were introduced to electrochemical research in 2000 as an alternative electrode material replacing more toxic mercury electrodes [ 45 ]. The developed voltammetric procedures with the use of the above electrodes have been described in the literature continuously since their first application, which is closely related to the excellent analytical properties of these electrodes [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ]. They have gained popularity mainly due to their lower toxicity and lower background current in the presence of oxygen compared to mercury electrodes.…”

“…Furthermore, these electrodes are characterized by the high sensitivity and repeatability of signals, and detection limits gained with their use do not differ from those obtained with mercury electrodes. BiFEs have been obtained by applying a bismuth film on a solid electrode made of glassy carbon [ 45 , 46 , 47 , 48 , 49 ], carbon paste [ 48 , 50 ], graphite pencil [ 48 ], impregnated graphite [ 51 ], and screen-printed carbon electrode [ 52 ]. The bismuth film can be applied by two methods, in situ or ex situ, and glassy carbon electrode is the most often used as a substrate for bismuth film [ 45 , 46 , 47 , 48 , 49 ].…”

An analytical procedure regarding the determination of selenium(IV) by anodic stripping voltammetry exploiting the in situ plated bismuth film electrode is described. Since organics are commonly present in untreated natural water samples, the use of Amberlite XAD-7 resin turns out to be quite important to avoid problems such as the adsorption of these compounds on the working electrode. The optimum circumstances for the detection of selenium in water using differential pulse voltammetry techniques were found to be as follows: 0.1 mol L−1 acetic acid, 1.9 × 10−5 mol L−1 Bi(III), 0.1 g Amberlite XAD-7 resin, and successive potentials of −1.6 V for 5 s and −0.4 V for 60 s, during which the in situ formation of the bismuth film on glassy carbon and the accumulation of selenium took place. The current of the anodic peak varies linearly with the selenium concentration ranging from 3 × 10−9 mol L−1 to 3 × 10−6 mol L−1 (r = 0.9995), with a detection limit of 8 × 10−10 mol L−1. The proposed procedure was used for Se(IV) determination in certified reference materials and natural water samples, and acceptable results and recoveries were obtained.

“…In addition, the electrical conductivity of the Ni-coated graphite felt is enhanced because of the lower electrical resistivity of Ni (69.9 nΩ•m) than that of graphite (2500 to 5000 nΩ•m) [76]. Cu-and Bi-coated carbon felts have also been reported [77][78][79]. Cu-coated graphite felts possess high electrical and thermal conductivities, and their wear-resistant properties (with fiber content above 10 vol %) are superior to those of wear-resistant Cu alloys.…”

Iron-chromium redox flow batteries (ICRFBs) have the advantages of high safety, long cycle life, flexible design, and low maintenance costs. Polyacrylonitrile-based graphite felt composite material has good temperature resistance, corrosion resistance, large surface area and excellent electrical conductivity, and is often used as the electrode material of ICRFB, but its chemical activity is poor. In order to improve the activity of the graphite felt electrode, In3+ was used for modification in this paper, and the modified graphite felt was used as the electrode material for iron-chromium batteries. The structure and surface morphology of the modified graphite felt were analyzed by the specific surface area analyzer and scanning electron microscope; the electrochemical impedance spectroscopy and cyclic voltammetry experiments were carried out on the electrochemical workstation to study the electro catalytic activity of In3+ modified graphite felt and its performance in ICRFBS. The results show that the graphite felt electrode modified with a concentration of 0.2 M In3+ was activated at 400°C for 2 h, and its surface showed a lot of grooves, and the specific surface area reached 3.889 m2/g, while the specific surface area of the untreated graphite felt was only 0.995 m2/g significantly improved. Electrochemical tests show that the electrochemical properties of graphite felt electrodes are improved after In3+ modification. Therefore, the In3+ modified graphite felt electrode can improve the performance of ICRFB battery, and also make it possible to realize the engineering application of ICRFB battery.
