Electrochemical oxygen reduction reaction (ORR) represents a crucial cathodic process of different fuel cells. The development highly active and stable noble metal-free ORR electrocatalysts remains as one major challenges. Herein, we report cobalt/nitrogen co-doped porous carbon materials (Co-N-C) originated from well-designed bimetal-organic frameworks (Zn100-xCox-ZIF) efficient in both pH-neu...

direct electron transferring of glucose oxidase was investigated   on reduced graphene and graphene oxide templates. the direct electrochemistry   glucose oxidase on   graphene showed a cyclic voltammograms corresponding to the fad/fadh 2   redox couple with an anodic, cathodic and formal potential of -430, -460 and   -445 mv, respectively in 0.1 m phosphate buffer solution and air saturated   ...

We present novel supported electro-catalytic systems based on metallic/bimetallic (Pt, Au-Pt) nanoparticles decorated carbon nanotubes Buckypaper (BP), and Bilirubin Oxidase (BOD) decorated Buckypaper-based biocathodes in neutral medium for direct glucose fuel cell. The electrodes have been tested for their suitability in mixed-reactant biofuel cell applications in a phosphate buffer solution (...

Palladium nanoparticles supported on carbon black powder (Vulcan XC-72) nanocomposite (Pd/C) are synthesized as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterization of the catalyst is carried out using physical and electrochemical methods. It is observed that Palladium nanoparticles are uniformly dispersed onto the carbon blac...

We have developed an implantable fuel cell that generates power through glucose oxidation, producing 3.4 μW cm(-2) steady-state power and up to 180 μW cm(-2) peak power. The fuel cell is manufactured using a novel approach, employing semiconductor fabrication techniques, and is therefore well suited for manufacture together with integrated circuits on a single silicon wafer. Thus, it can help e...

Biofuel cells have received significant attention in the last few decades due to its potential application as alternative energy sources and advantages over conventional fuel cells. This review summarizes different types of glucose biofuel cells with emphasis on enzymatic glucose biofuel cells. Unlike conventional fuel cells, which use fuel such as ethanol, methanol, formic acid, etc. to genera...

The electrochemical features of microbial fuel cells’ biocathodes, running on wastewater, were evaluated by cyclic voltammetry. Ex situ and in assays performed the redox processes associated with presence microorganisms and/or biofilms attained. Different controls using sterile media (abiotic cathode cell) membranes covering electrodes to evaluate source electrochemistry response (surface vs. b...

Newly synthesized Polypropylene-g-Polyethylene glycol polymer was first time used for a compartment-less enzymatic fuel cell. Working electrodes based on Polypropylene-g-Polyethylene glycol were operated as unmediated and mediated system (with ferrocene and gold/cobalt oxide nanoparticles). Glucose oxidase and bilirubin oxidase was selected as anodic and cathodic enzyme, respectively. Glucose w...
