Molybdenum carbide as anodic catalyst for microbial fuel cell based on Klebsiella pneumoniae

A facile synthesis of molybdenum carbide nanoparticles-modified carbonized cotton textile as an anode material for high-performance microbial fuel cells

“…18 More importantly, Mo 2 C nanoparticles exhibit good biocompatibility and excellent electrocatalytic activity towards oxidation of bacterial metabolites. [19][20][21][22] Unfortunately, as previously reported, the conditions for synthesis of Mo 2 C nanoparticles are very strict and the true of product is hard to control. 20,21 In this study, Mo 2 C/CCT was developed as anode material for high-performance MFCs via a facile two-step method (dipping and carbonization treatment).…”

“…[19][20][21][22] Unfortunately, as previously reported, the conditions for synthesis of Mo 2 C nanoparticles are very strict and the true of product is hard to control. 20,21 In this study, Mo 2 C/CCT was developed as anode material for high-performance MFCs via a facile two-step method (dipping and carbonization treatment). The Mo 2 C/CCT electrode provides a high conductivity, a rough surface and a large specic surface area for bacterial adhesion on the anode, facilitates the formation of electroactive biolm, as well as displays superior electrochemical activity.…”

Preparation of molybdenum carbides with multiple morphologies using surfactants as carbon sources

“…These two methods use solid carbons including activated carbon and carbon aerogel as carbon sources to carburize vaporized metal oxides or supported metal oxides in flowing hydrogen. Solution derived precursor method is developed in recent years [12][13][14]. In this method, the molybdenum peroxides precursor is firstly prepared, then polymers are added to form colloidal molybdenum; the colloidal molybdenum is then annealed to form molybdenum carbides.…”

Mo2C/Reduced Graphene Oxide Composites with Enhanced Electrocatalytic Activity and Biocompatibility for Microbial Fuel Cells

“…reported that tungsten carbide (WC) exhibited superior electrocatalytic performance towards the fermentation of glucose and delivered a maximum power density of 5.85 Wm −2 when used as an anodic catalyst in MFCs [8a] . Similarly, the MFCs device based on carbon felt anode decorated with β‐molybdenum carbide yielded a maximum power output of 2.39 Wm −3 , which was comparable to that of Pt/C‐MFCs (3.64 Wm −3 ) [11] . However, these transition metal carbides usually suffer from poor conductivity, which will form physical barriers for the electron transfer from the microorganism or mediator to the carbon anode.…”

“…Among various electrocatalysts, transition metal carbides with comparable electrocatalytic properties to Pt have received increasing attention as they are capable of enhancing the performance of MFCs [8a, b, 9–10] . It is reported that they presented intriguing catalytic activities towards the oxidation of several microbial fermentation metabolites (such as hydrogen, [3a] formate, ethanol [11] ) as well as the endogenous electron shuttles (such as flavin [10b, c] ). For instance, Rosenbaum et al.…”
