    • Earth-Abundant Electrocatalysts in Proton Exchange Membrane Electrolyzers 

      Sun, Xinwei; Xu, Kaiqi; Fleischer, Christian; Liu, Xin; Grandcolas, Mathieu; Strandbakke, Ragnar; Bjørheim, Tor Svendsen; Norby, Truls Eivind; Chatzitakis, Athanasios Eleftherios (Journal article; Peer reviewed, 2018)
      In order to adopt water electrolyzers as a main hydrogen production system, it is critical to develop inexpensive and earth-abundant catalysts. Currently, both half-reactions in water splitting depend heavily on noble metal ...

    • In-situ electron loss spectroscopy reveals surface dehydrogenation of hydrated ceria nanoparticles at elevated temperatures 

      Thøgersen, Annett; Sun, Xinwei; Jensen, Ingvild Julie Thue; Prytz, Øystein; Norby, Truls (Peer reviewed; Journal article, 2022)
      Ceria (CeO2) exhibits high reversible oxygen storage capacity at intermediate temperatures (500–800 °C) related to an extraordinary and not fully understood reduction of its surfaces. We have investigated pristine and ...

    • Surface protonic conductivity in chemisorbed water in porous nanoscopic CeO2 

      Sun, Xinwei; Vøllestad, Einar; Rørvik, Per Martin; Prodinger, Sebastian; Kalantzopoulos, Giorgios N.; Chatzitakis, Athanasios; Norby, Truls (Peer reviewed; Journal article, 2023)
      CeO2 surfaces play decisive roles in heterogeneous catalysis of important processes. Here, we investigate adsorption and dissociation of water and migration of protons on internal surfaces of nanoscopic porous CeO2. Sorption ...
