Dynamic electrochemical impedance study of methanol oxidation at Pt at elevated temperatures
Holm, Thomas; Dahlstrøm, Per Kristian; Sunde, Svein; Seland, Frode; Harrington, David A. (Journal article; Peer reviewed, 2019)The methanol oxidation reaction (MOR) is studied at temperatures up to 140 °C by a combination of cyclic voltammetry, chronoamperometry, and dynamic electrochemical impedance spectroscopy (dEIS). A mechanistic analysis of ... -
Electro-oxidation of ethanol at Pt electrodes with the use of a Dynamic Electrochemical Impedance Spectroscopy (DEIS) technique
Døssland, Line Teigen (Master thesis, 2012)Electro-oxidation of ethanol on smooth platinum surfaces was studied in thetemperature range 21C to 140C for 0.2 M ethanol in 0.5 M sulphuric acid.This was done by use of cyclic voltammetry and electrochemical impedances ... -
Electro-oxidation of small organic molecules
Dahlstrøm, Per Kristian (Doktoravhandlinger ved NTNU, 1503-8181; 2012:348, Doctoral thesis, 2012)An alternative to fossil fuels is to utilize biofuels like methanol and ethanol directly in fuel cells. One drawback of this system is the sluggish reaction kinetics in methanol and ethanol oxidation where strongly bound ... -

Method for studying high temperature aqueous electrochemical systems: Methanol and glycerol oxidation
Holm, Thomas; Dahlstrøm, Per Kristian; Burheim, Odne Stokke; Sunde, Svein; Harrington, David A.; Seland, Frode (Journal article; Peer reviewed, 2016)A method for high purity aqueous electrochemical experiments at temperatures above the normal boiling point of water and at temperatures up to 140 °C is described. A three-electrode cell in a self-pressurized glass autoclave ... -
Microfluidic flow cells for studies of electrochemical reactions
Møinichen, Christine (Master thesis, 2012)In this project the main goal was to establish a routine for making a microfluidic flow cell (MFFC) using soft lithography methods, and test the flow cell with different electrolytes, sulphuric acid and a ruthenium red-ox ...
