“…However, graphene shows some antibacterial effect on the initial biofilm growth of Shewanella MR (i.e., a well-known EAB). The electrochemical activity of the Shewanella MR biofilm on a graphene-modified anode was 70% lower than that on a graphite anode (Chen et al, 2015). Graphene oxide, a precursor of graphene, can act as a terminal electron acceptor for Shewanella sp.…”

“…A H 2 O 2 solution (30%) was titrated into the mixed solution until the color of the solution was changed to luminous yellow. After the mixture was centrifugalized, the precipitate was washed with diluted hydrochloric acid until SO 4 2-was not detectable, and then washed with pure water until pH of washing solution became 7.0. A GO dispersed solution of 20 mg/mL was obtained after concentrated.…”

“…Li et al prepared monolayer graphene films on insulator SiO 2 , semiconductor Ge and conductor Cu using atmospheric pressure chemical vapor deposition (APCVD) . Graphene could acts as electron acceptor and attracted electrons away from the bacterial membrane, resulting in compromised membrane integrity . Thus, the graphene‐SiO 2 material exhibited neither electron transfer nor antibacterial activity because SiO 2 cannot transfer electrons.…”

Graphene materials have unique structures and outstanding thermal, optical, mechanical and electronic properties. In the last decade, these materials have attracted substantial interest in the field of nanomaterials, with applications ranging from biosensors to biomedicine. Among these applications, great advances have been made in the field of antibacterial agents. Here, recent advancements in the use of graphene and its derivatives as antibacterial agents are reviewed. Graphene is used in three forms: the pristine form; mixed with other antibacterial agents, such as Ag and chitosan; or with a base material, such as poly (N-vinylcarbazole) (PVK) and poly (lactic acid) (PLA). The main mechanisms proposed to explain the antibacterial behaviors of graphene and its derivatives are the membrane stress hypothesis, the oxidative stress hypothesis, the entrapment hypothesis, the electron transfer hypothesis and the photothermal hypothesis. This review describes contributions to improving these promising materials for antibacterial applications.

“…These studies revealed the great potential of using graphene to improve the electrode performance in MFCs. After that, some studies demonstrate that graphene-modified carbon cloth (CC) or graphite plate (GP) electrode exhibit higher power density than that of bare CC, activated carbon or the bare graphite modified electrode [17,[70][71][72]. Some previous studies reported three-dimensional (3D) anodes were prepared by the graphene sponge (GS), which provided 3D open space with a large area for microbial colonization (Figs 5a and d).…”

Microbial fuel cells (MFCs) are environmentally friendly technology capable of converting chemical energy stored in wastewaters directly into electrical energy by using microorganisms as biocatalysts. However, the overall low power density of the MFC and the high cost of its components are two major barriers for its commercialization. Among all the factors, the electrodes (cathode and anode) materials play the significant role in affecting the performance of MFCs. Recently, the performance of MFCs has been improved by using graphene-based electrodes that are more conductive and mechanically stable with larger surface area and higher electrocatalytic activity compared to the conventional carbon materials. This paper provides an overview of recent research progress in graphene-based materials as electrodes for MFCs, which will be the promising candidates for developing MFCs and other bioelectrochemical systems to achieve sustainable water/wastewater treatment and bioenergy production.
