A carbon particle network working electrode allows control over a wide potential window without the need for solution mediators.EC/FP7/258600/EU/Understanding and Exploiting Biological Catalysts for Energy Cycling: Development of Infrared Spectroelectrochemistry for Studying Intermediates in Metalloenzyme Catalysis/ENERGYBIOCATALYSISDFG, EXC 314, Unifying Concepts in Catalysi
