Improved microbial electrocatalysis with osmium polymer modified electrodes

Chem Commun (Camb). 2012 Oct 21;48(82):10183-5. doi: 10.1039/c2cc34903e.

Abstract

Using the well-known exoelectrogen Shewanella oneidensis MR-1, an osmium redox polymer modified anode exhibited ca. 4-fold increase in current generation. Additionally, a significant decrease in the start-up time for electrocatalysis was observed. The findings suggest that the inherent extracellular electron transfer capabilities of electrogens coupled with such polymers could enhance electrocatalysis.
