“…Previous research showed that anode modifications using nanomaterials could increase the electrochemical activity of outer-membrane c-type cytochromes, leading to the enhanced DET in S. oneidensis MR-1 (Deng et al, 2010;Peng et al, 2010;Huang et al, 2011). Meanwhile, several efforts were also made on the physical and chemical immobilization of electron shuttles directly onto electrode to improve the shuttle-mediated EET efficiency (Adachi et al, 2008;Feng et al, 2010;Wang et al, 2011). Here, our work implied that it was possible for improved physical absorption of electron shuttles on electrode interfaces by nitrogen doped modification on electrode materials, providing a new approach in the rational design of novel electrode materials for high-performance MFCs and other bioelectrochemical systems.…”

“…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.

“…Anode modification has been reported to be an effective alternative to chemical binding of mediators. It has been investigated and suggested by several authors based on economical effectiveness and expected successful application at large scale . Based on reviewed literature, ammonia and heat treatment are the most economical and practical for large‐scale implementation.…”

Application of the Fenton process for textile wastewater treatment is limited due to high treatment cost, substantially contributed by the un‐availability of cheap hydrogen peroxide. Therefore, alternative methods for hydrogen peroxide production are in demand. One such option is in situ hydrogen peroxide production using a wastewater based microbial fuel cell (WBMFC). However, not much have been published regarding in situ production of hydrogen peroxide for textile wastewater treatment in a WBMFC. Therefore, in this work the concept, advantages, challenges and prospects of using WBMFC to treat textile wastewater by simultaneously producing hydrogen peroxide (hence in situ hydrogen peroxide) and power are reviewed. The concept of WBMFC is the reduction of oxygen in the presence of electrons and protons from the anode chamber to produce hydrogen peroxide with simultaneous power production. This review confirms that use of dual chambers, proton exchange membrane, domestic or municipal wastewater/Geobacter Sulfurreducens or Shewanella species, pure graphite cathode, ammonia and heat treated carbon‐based anode can treat most textile wastewaters. However, single chamber WBMFCs can be used as a low power source for an electro‐Fenton reactor. Power produced can be used to provide energy for aeration required in the WBMFC, thus providing an integrated and sustainable solution for textile wastewater treatment. © 2014 Society of Chemical Industry
