Nano-Litre Proton/Hydrogen Titration in a Dual-Plate Platinum-Platinum Generator-Collector Electrode Micro-Trench

Abstract:

A generator-collector "nano-litre cavity" based on two opposed platinum-coated gold film electrodes with 19 μm gap and either 38 μm or 83 μm depth is employed for the titration of protons and/or hydrogen. Diffusional feedback currents between generator and collector electrode in a platinum-platinum dual-plate sensor configuration provide a sensitive analytical tool for cycleable redox systems, here, the proton/hydrogen redox system in the presence of oxygen. Experimental data are compared wit...
