Bimetallic Nano Electrocatalyst for HER in Alkaline Polymer Electrolysis
Faid, Alaa; Manikandan, Maidhily; Seland, Frode; Barnett, Alejandro; Sunde, Svein (Peer reviewed; Journal article, 2018)Ni and alloys of Ni (with Fe, Co, Mo) still represent the most suitable electrodes for HER in alkaline media. Bimetallic nanoparticles of NiFe and NiCo were fabricated by co-precipitation and thermal reduction by oleylamine. ... -

Xu, Wenting; Haarberg, Geir Martin; Sunde, Svein; Seland, Frode; Ratvik, Arne Petter; Zimmerman, Erik; Shimamune, T; Gustavsson, J; Åkre, Torjus (Peer reviewed; Journal article, 2017) -
Electrochemical Behaviour of Industrial IrO2-Ta2O5 Anodes for Copper Electrowinning
Xu, Wenting; Haarberg, Geir Martin; Sunde, Svein; Seland, Frode; Ratvik, Arne Petter; Zimmerman, Erik; Shimamune, Takayuki; Åkre, Torjus (Peer reviewed; Journal article, 2017) -
Highly Active Nickel-Based Catalyst for Hydrogen Evolution in Anion Exchange Membrane Electrolysis
Faid, Alaa; Barnett, Alejandro; Seland, Frode; Sunde, Svein (Journal article; Peer reviewed, 2018)Anion exchange membrane (AEM) electrolysis is hampered by two main issues: stability and performance. Focusing on the latter, this work demonstrates a highly active NiMo cathode for hydrogen evolution in AEM electrolysis. ... -
Ni/NiO nanosheets for alkaline hydrogen evolution reaction: In situ electrochemical-Raman study
Faid, Alaa; Barnett, Alejandro Oyarce; Seland, Frode; Sunde, Svein (Peer reviewed; Journal article, 2020)Nickel/Nickel oxide (Ni/NiO) nanosheets heterostructure is a cheap and active catalyst for hydrogen evolution reaction (HER) in alkaline electrolytes. However, the reason for this activity is still under debate. Herein ... -
Platinum and Platinum Group Metal-Free Catalysts for Anion Exchange Membrane Fuel Cells
Truong, Van Men; Tolchard, Julian R; Svendby, Jørgen; Manikandan, Maidhily; Miller, Hamish; Sunde, Svein; Hsiharng, Yang; Dekel, Dario; Barnett, Alejandro Oyarce (Peer reviewed; Journal article, 2020)The development of active hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) catalysts for use in anion exchange membrane fuel cells (AEMFCs), which are free from platinum group metals (PGMs), is expected ... -
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 (Peer reviewed; Journal article, 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
