  • Alkali metals as efficient A-site acceptor dopants in proton conducting BaZrO3 
    Løken, Andreas; Saeed, Sarmad Waheed; Norderhaug, Marit; Liu, Xin; Bjørheim, Tor Svendsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    In the present contribution, we assess the efficiency of the alkali metals (Na, K, Rb and Cs) as A-site acceptor dopants in proton conducting BaZrO3 by first principles calculations. The calculated acceptor–proton complexes ...
  • 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 / Tidsskriftartikkel / PublishedVersion; 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 ...
  • Galvanic Deposition of Pt Nanoparticles on Black TiO2 Nanotubes for Hydrogen Evolving Cathodes 
    Touni, Aikaterini; Liu, Xin; Kang, Xiaolan; Almeida Carvalho, Patricia; Diplas, Spyridon; Both, Kevin Gregor; Sotiropoulos, Sotiris; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    A galvanic deposition method for the in-situ formation of Pt nanoparticles (NPs) on top and inner surfaces of high-aspect-ratio black TiO2-nanotube electrodes (bTNTs) for true utilization of their total surface area has ...
  • Highly Correlated Hydride Ion Tracer Diffusion in SrTiO3–xHx Oxyhydrides 
    Liu, Xin; Bjørheim, Tor Svendsen; Vines, Lasse; Fjellvåg, Øystein; Granerød, Cecilie Skjold; Prytz, Øystein; Yamamoto, Takafumi; Kageyama, Hiroshi; Norby, Truls Eivind; Haugsrud, Reidar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Mixed oxide hydride anion systems constitute a novel class of materials exhibiting intriguing properties such as solid-state hydride ion conduction and fast anion exchange. In this contribution we derive the kinetics of ...
  • Immobilization of FeFe-hydrogenase on black TiO2 nanotubes as biocathodes for the hydrogen evolution reaction 
    Liu, Xin; Risbakk, Sanne; Almeida Carvalho, Patricia; Yang, Mingyi; Backe, Paul Hoff; Bjørås, Magnar; Norby, Truls; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Hydrogenases are attractive biocatalysts for utilization in electrochemical devices as potential replacement for Pt in hydrogen evolving electrodes. In this work, we investigate the immobilization of ferredoxin tagged ...
  • Impedance of a tubular electrochemical cell with BZCY electrolyte and Ni-BZCY cermet electrodes for proton ceramic membrane reactors 
    Yuste Tirados, Irene; Liu, Xin; Kjølseth, Christian; Norby, Truls (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    In this work, impedance spectroscopy has been employed to explore the electrochemical behaviour of a 15 cm2 complete tubular cell with BaZr0.8Ce0.1Y0.1O3-δ (BZCY) electrolyte and two asymmetric Ni-BCZY cermet electrodes ...
