Calcination temperature dependent catalytic activity and stability of IrO2 – Ta2O5 anodes for oxygen evolution reaction in aqueous sulfate electrolytes
Xu, Wenting; Haarberg, Geir Martin; Sunde, Svein; Seland, Frode; Ratvik, Arne Petter; zimmerman, erik; Shimamune, T; Gustavsson, J; Åkre, Torjus (Journal article; Peer reviewed, 2017)In this work, commercial IrO2-Ta2O5 anodes with a certain composition calcined at three different temperatures were investigated. The results show that the calcination temperature has a significant influence on the ... -
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), ... -
The IrO2-Ta2O5 Coated Titanium Anode for Oxygen Evolution Reaction in Sulfate Solution
Xu, Wenting (Doctoral theses at NTNU;2018:320, Doctoral thesis, 2018)Titanium substrates coated with a conductive layer of metal oxides are well known gas evolving electrodes in the metal electrowinning industry, so-called dimensionally stable anodes (DSAs). DSA electrodes display better ...
