The electrochemical oxidation of CH 3 OH at nanometer-scale PtRu catalyst materials is reported. Comparisons are made between the properties of a Johnson Matthey (JM) PtRu black sample (50 at.% Ru (X Ru ≈0.5)) and PtRu particles (2–6 nm, nominally X Ru ≈0.5) prepared by sonication under anhydrous conditions. Cyclic voltammetry and in situ infrared spectroscopy measurements...
The use of a micro-volume infrared transmission flow cell for quantitative determinations of CO 2 dissolved in solutions following electrochemical oxidation reactions is described. Results are compared with previous in situ infrared measurements as a step toward evaluating the performance of infrared spectroelectrochemical cells under conditions where non-ideal optical effects can become important...
