    • Electrochemical Behaviour of Industrial IrO2-Ta2O5 Anodes for Copper Electrowinning 

      Xu, Wenting; Haarberg, Geir Martin; Sunde, Svein; Seland, Frode; Ratvik, Arne Petter; Zimmerman, Erik; Åkre, Torjus (Journal article; Peer reviewed, 2017)
      In this work, industrial IrO2-Ta2O5 anodes calcined at different temperatures were investigated. The results show that the calcination temperature has significant influence on the surface microstructure including the ...

    • Sandblasting effect on performance and durability of Ti based IrO2 –Ta2O5 anode in acidic solutions 

      Xu, Wenting; Haarberg, Geir Martin; Sunde, Svein; Seland, Frode; Ratvik, Arne Petter; Holmin, Susanne; Gustavsson, J; Afvander, Åsa; Zimmerman, Erik; Åkre, Torjus (Journal article; Peer reviewed, 2018)
      The effect of applying sandblasting during pretreatment while preparing titanium based IrO2 – Ta2O5 anodes by the conventional method was investigated. It was observed that sandblasting influences the surface morphology ...

    • The durability of the thermally decomposed IrO2-Ta2O5 coated titanium anode in a sulfate solution 

      Xu, Wenting; Haarberg, Geir Martin; Seland, Frode; Sunde, Svein; Ratvik, Arne Petter; Holmin, Susanne; Afvander, Åsa; Gustavsson, John; Zimmerman, Erik; Årke, Torjus (Journal article; Peer reviewed, 2019)
      In this work, series of IrO2-Ta2O5 anodes were investigated. The catalytic activity towards oxygen evolution reaction (OER) of these anodes are determined by calcination temperature, coating loading (coating thickness), ...
