• Electrochemical behaviour of dissolved iron chloride in KCl+LiCl+NaCl melt at 550 ºC 

      Khalaghi, Babak; Kvalheim, Eirin; Tokushige, Manabu; Teng, Lidong; Seetharaman, S.; Haarberg, Geir Martin (Journal article, 2014)
      An electrochemical study of iron was carried out in KCl+LiCl+NaCl melt at 550ºC using a glassy carbon working electrode. Cyclic voltammetry showed that the Fe(II)/Fe(0) electron exchange is a soluble/insoluble reversible ...
    • Electrodeoxidation of Iron Oxide in Aqueous NaOH Electrolyte 

      Haarberg, Geir Martin; Khalaghi, Babak (Peer reviewed; Journal article, 2020)
      The production of iron and steel contributes to ~10 % of global CO2 emissions. Electrolysis is an alternative route to eliminate CO2 formation. Experiments were carried out in NaOH-H2O (50-50 wt%) electrolyte with a ...
    • Gas Anodes Made of Porous Graphite for Aluminium Electrowinning 

      Khalaghi, Babak; Gudbrandsen, Henrik; Kjos, Ole Sigmund; Osen, Karen Sende; Paulsen, Ove; Mokkelbost, Tommy; Haarberg, Geir Martin (Journal article, 2017)
      One of the major downsides of the current aluminium production process is the high CO2 emission. One alternative is to replace the consumable carbon anodes with inert anodes so that oxygen evolves instead of CO2. Also PFC ...
    • Natural Gas Anodes for Aluminium Electrolysis in Molten Fluorides 

      Haarberg, Geir Martin; Khalaghi, Babak; Mokkelbost, Tommy (Journal article; Peer reviewed, 2016)
      Industrial primary production of aluminium has been developed and improved over more than 100 years. The molten salt electrolysis process is still suffering from low energy efficiency and considerable emissions of greenhouse ...
    • Natural Gas Anodes of Porous Graphite for Aluminium Electrolysis 

      Khalaghi, Babak (Doctoral theses at NTNU;2017:266, Doctoral thesis, 2017)
      Aluminium is the second metal produced in the world in terms of quantity. It is produced in a multistage process. First, aluminium ore is converted to pure aluminium oxide. The second stage is an electrolysis process. In ...
    • Porous Carbon Anodes for the Supply of Methane during Electrowinning of Aluminium 

      Khalaghi, Babak; Gudbrandsen, Henrik; Kjos, Ole Sigmund; Osen, Karen Sende; Mokkelbost, Tommy; Haarberg, Geir Martin (Chapter, 2016)
      One of the major downsides of the current aluminium production process is the high amount of CO2 e mission. One alternative is to replace the consumable carbon anodes with inert anodes so that oxygen evolves instead of CO2 ...
