Biofuel Cells: Enhanced Enzymatic Bioelectrocatalysis

Annual Review of Analytical Chemistry, 2012
Enzymatic biofuel cells represent an emerging technology that can create electrical energy from biologically renewable catalysts and fuels. A wide variety of redox enzymes have been employed to create unique biofuel cells that can be used in applications such as implantable power sources, energy sources for small electronic devices, self-powered ...

Nitrogenase Bioelectrocatalysis

ECS Meeting Abstracts, 2019
Nitrogenase is the only enzyme capable of nitrogen reduction to ammonia. This talk will discuss cobaltocene and methyl viologen mediation schemes for MoFe and VFe nitrogenase, as well as strategies for nitrogenase bioelectrocatalysis in air. Bioelectrocatalysis of proton reduction, azide reduction, nitrite reduction, nitrogen reduction, and carbon ...

MET-Type Bioelectrocatalysis

2020
This chapter deals with theoretical features of MET-type bioelectrocatalysis with emphasis of steady-state serial reactions. The fundamental concept in the selection of mediators is described based on linear free energy relationship and diffusion-controlled kinetics.

Redox Proteins and Bioelectrocatalysis

2020
This chapter starts by introducing the basic feature and thermodynamics of redox proteins including redox enzymes (oxidoreductases). Biochemical properties of organic and inorganic redox components in redox enzymes are detailed, and they are very important to understand bioelectrocatalysis.

Bioelectrocatalysis: the electrochemical kinetics of hydrogenase action

Journal of Biotechnology, 1993
A hydrogen electrode based on a hydrogenase immobilized on a carbon material has been developed. The equilibrium hydrogen potential was reached in an atmosphere of H2 on the enzyme electrode according to the mechanism of direct exchange of electrons between the electrode and the enzyme active center.

Bioelectrocatalysis by redox enzymes at modified electrodes

Reviews in Molecular Biotechnology, 2002
Self-assembled monolayers of thiolated compounds are used as promoters for protein-electrode reactions. They provide an anchor group based on thiol chemisorptions and also a functional group for effective interaction with the protein. These interactions are often governed by electrostatic attraction.
