“…Briefly, the Cu foil was annealed in a split tube furnace at 1030 8C for 30 min with Ar and H 2 flow at 1470 sccm and 27 sccm, respectively, which was held constant throughout the whole procedure. The temperature was decreased to 1000 8C and graphene growth was initiated by bleeding 3 sccm CH 4 into the reaction chamber. The growth proceeded for 1 h (pressure = 28 mbar), after which the tube was rapidly cooled to room temperature.…”

“…Because of this feature AQ-functionalised substrates have shown promising applications in (bio)sensors [1][2][3], biofuel cells [4] and electrocatalysis, including the production of hydrogen peroxide via oxygen reduction reaction (ORR) [5][6][7][8][9][10][11][12][13][14][15][16]. Various electrode materials (carbon as well as metals) have been surface-modified with AQ and its derivatives [3,8,9,12,13,[17][18][19][20][21][22][23][24][25][26][27][28][29] and, in general, carbon-based materials are attractive because of their good conductivity, low cost, and wide electrochemical window [30].…”

Electrochemical Behaviour of HOPG and CVD‐Grown Graphene Electrodes Modified with Thick Anthraquinone Films by Diazonium Reduction

et al. 2014

Highly oriented pyrolytic graphite (HOPG) and graphene grown on Ni (Ni‐Gra) or Cu (Cu‐Gra) by chemical vapour deposition were modified with thick anthraquinone (AQ) films (7−60 nm) by redox grafting of the pertinent diazonium salt. Glassy carbon (GC) electrodes were used for comparison. The AQ‐modified GC electrodes showed excellent blocking properties towards the Fe(CN)63−/4− redox probe, although it was noted that in the case of Ni‐Gra and Cu‐Gra, the blocking ability depended strongly on the underlying substrate. Oxygen reduction studies revealed good electrocatalytic activity of AQ‐modified HOPG, Ni‐Gra, and Cu‐Gra, compared with the bare electrodes.

“…Recently polymeric quinone was used to electrically connect photosystem II to the electrode, which functioned as the anode of a water splitting photo-bioelectrochemical cell (Figure 15(a)). 84 Quinonemodified electrodes were also used for efficient electron exchange with bacterial cells and applied to sensing toxic substances metabolized by bacteria 85 as well as increasing power output of microbial fuel cells [86][87][88] (Figure 15(b)). Quinone-functionalized chitosan electrodes could be used as a biological redox capacitor that can exchange electrons with biological components in solution, and later convert the amount of charge stored into electronic signal (Figure 15(c)).…”

This tutorial review provides a general account of the electrochemical behavior of quinones and their various applications. Quinone electrochemistry has been investigated for a long time due to its complexity. A simple point of view is developed that considers the relative stability of the reduced quinone species and the values of the first and second reduction potentials. The 9-membered square scheme in buffered aqueous solutions is explained and semiquinone radical stability is discussed in this context. Quinone redox reaction has also been employed in various studies. Diverse examples are presented under three broad categories defined by the roles of quinone: molecular tool for physical chemistry, versatile electron mediator, and charge storage for energy conversion devices.

“…In a half-cell test using an anode only, they observed 60 times increase in current density compared to unmodified electrode. Feng et al 19 performed nearly the same experiments as Adachi et al using polypyrrole-attached AQDS as a surface-confined mediator and Shwanella decolorationis S12 as a biocatalyst. They reported P max of 1300 mWm −2 with current density of 2.75 Am −2…”

As anode fabrication with different materials has been proven to be a successful alternative for enhancing power generation in the microbial fuel cells, a new approach to improved performance of MFCs with the use of menadione/carbon powder composite-modified carbon cloth anode has been explored in this study. Menadione has formal potential to easily accept electrons from the outer membrane cytochromes of electroactive bacteria that can directly interact with the solid surface. Surface bound menadione was able to maintain an electrical wiring with the trans-membrane electron transfer pathways to facilitate extracellular electron transfer to the electrode. In a single chamber air cathode MFC inoculated with aerobic sludge, maximum power density of 1250 ± 35 mWm −2 was achieved, which was 25% higher than that of an unmodified anode. The observed high power density and improved coulomb efficiency of 61% were ascribed to the efficient electron shuttling via the immobilized menadione.
