“…7C), indicating the prepared 3D Pt 3 Ni 7 /MWCNTs nanocomposites enhance high stability to the GOR and ORR in the GBFCs system. The results compare well with glucose bioelectrodes subject to continuous operations reported in literature [33][34][35][36]42,43].…”

“…It is worth mentioning that the fabricated 3D Pt x Ni 1Àx /MWCNTs electrodes exhibit prominent electrocatalytic performance for application as anode and cathode in GBFCs. We consider that the outstanding electrocatalytic activity should be attributed to the following advantages: (i) MWCNTs exhibit high specific surface, antifouling properties, unique electronic properties and ease of surface modification; (ii) nanoscale Pt structures provide preferable electrochemical properties and biocompatibility, compared to bulk Pt materials; (iii) recently, nickel and nickel oxyhydroxides are known to catalyze the GOR and ORR [43], namely that nickel and nickel hydroxides in the alloy nanocatalysts acting not only as promoters but also as catalysts are capable of oxidizing glucose and reducing oxygen in mild solution; (iv) the PtNi alloy electrocatalysts may promote lower adsorption strengths for the oxygenated intermediate species on the Pt surface and lower PteO coverage due to the faster PteO reduction. In addition, PteOH ad formation is inhibited on Pt sites by the Ni oxides [23,24].…”

“…Taking into consideration the Table 1, it can be also stated that a little amount of Pt introduced also in pure nonprecious metals, such as Ni [52,53], Co [10,54], Cu [55] and Pd [56] can enhance GOR as well as can broad the detection range. Among them Co and Ni can shift the concentration range to lower values (Table 1).…”

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.

“…Various methods have been used for the fabrication of nanostructures, like molecular beam epitaxy (MBE) [31,32], sol-gel [33,34], chemical vapor deposition (CVD) [35,36], lithography [37,38], physical vapor deposition (PVD) [39], and chemical methods [40][41]. Among these methods, the low cost and high efficiency technologies have attracted more attention.…”
