“…Despite the fact that Pd-based electrocatalysts present better activity in alkaline environment than those based on Au and Pt, there are still not many relevant works in literature. Very recently our research group studied a series of Pdbased electrocatalysts in alkaline media, such as Pd x Rh y /C [24], Pd x Sn y /C [75], Pd x Au y /C [76], Pd x Au y -NH 3modified [82] and PdCeO 2 /C [83]. More precisely, the first two were examined as anode materials for GOR, while the latter three ones were tested as material for glucose sensors.…”

The up-to-date research as far as it concerns the abiotic direct glucose fuel cells (DGFCs) is summarized and discussed in the present review. Platinum and goldbased as well as Raney-type electrocatalysts are among the most studied ones. In abiotically (non-implantable) DGFCs, unsupported Pt and PtRuO 2 , exhibited good activity (power density *20 mW cm -2 ), at room temperature and at atmospheric pressure. On the other hand, Au-based electrocatalysts adopted in a DGFC resulted in power densities up to ca. 5 mW cm -2 , exhibiting however high poisoning tolerance. Recently, after the introduction of alkaline membranes into the market, Pd-based electrocatalysts have attracted the attention of the research community because of their enhanced activity in alkaline media. However, there are still very few investigations where membrane electrode assemblies with palladium electrocatalysts have been applied. Moreover, Raney-type electrocatalysts, not yet examined for other fuels in direct polymer electrolyte fuel cells, are considered to be the most appropriate for implantable abiotic DGFCs. A novel implantable fuel cell in a human brain performed with 3.4 9 10 -3 lW power for 10 h adopting Raney-type electrocatalysts.

“…Typically, AA and uric acid (UA) in the blood can interfere with the oxidation of D-glucose by active catalysts, but these two substances have been shown to produce a negligible signal and have little impact on Pd catalysts upon amperometrically sensing D-glucose using minor convection [25,[44][45][46]. In addition, this observation has been confirmed in the case of 27-nm Pd NCs used as a GOR catalyst [28].…”

“…15,16 C 6 H 12 O 6 is fed directly to the anode of a DGFC, which can produce 24 electrons via full electrooxidation to CO 2. Pd, 20 Pd-Au, 21,22 Pd-Bi, 23 CuO-ZnO nano-flowers, 24 MnOx/NiOx, 25 Pd-SnCoOx, 26 Fe-Ni-Co, 27 and Au-Pt-Pd 28 catalysts have been investigated and evaluated as anode catalysts for DGFCs. 19 In most studies, researchers have attempted to develop efficient and stable electrocatalysts for C 6 H 12 O 6 electrooxidation in the alkaline environment.…”

Summary At present, N‐, S‐, and B‐doped grapheme‐modified indium tin oxide (ITO) electrodes are produced and doping method effect on the glucose electrooxidation is investigated. Firstly, few‐layer graphene is produced by chemical vapor deposition (CVD) method. Then, N, S, and B doping is carried out after graphene produced by CVD to prepare N‐doped, B‐doped, and S‐doped few‐layer graphene. N, S, and B doping is carried out by two different ways as (a) doping after synthesis of few‐layer graphene and (b) in situ doping during few‐layer graphene production. These materials are characterized by X‐ray diffraction, scanning electron microscopy‐energy (SEM), Raman spectroscopy, and X‐ray photoelectron spectroscopy (XPS). One could note that graphene and nitrogen networks are clearly visible from SEM images. Raman spectra show that B, N, and S are doped on few‐layer graphene/ITO successfully. XPS results of graphene, N‐doped graphene, and in situ N‐doped graphene reveal that graphene and nitrogen atoms used in the preparation of the electrodes obtain mainly in their elemental state. Then, these N‐, S‐, B‐doped and in situ N‐, S‐, B‐doped few‐layer graphene materials are coated onto indium tin oxide (ITO) to obtain N‐, S‐, B‐doped and in situ N‐, S‐, B‐doped ITO electrodes for glucose (C6H12O6) electrooxidation. C6H12O6 electrooxidation measurements are investigated with cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy measurements. As a result, in situ N‐doped few‐layer graphene/ITO electrode displays the best C6H12O6 electrooxidation activity with 9.12 mA.cm−2 current density compared with other N‐, S‐, B‐doped graphene and in situ doped S and B grapheme‐modified ITO electrodes. Furthermore, this current density value for in situ N‐doped few‐layer graphene/ITO is highly above the values reported in the literature. In situ N‐doped few‐layer graphene/ITO electrode is a promising electrode for C6H12O6 electrooxidation because it exhibits the best electrocatalytic activity, stability, and resistance compared with other electrodes.
