  • Double Perovskite Cobaltites Integrated in a Monolithic and Noble Metal-Free Photoelectrochemical Device for Efficient Water Splitting 
    Zhu, Junjie; Guðjónsdóttir, Jónína; Strandbakke, Ragnar; Both, Kevin Gregor; Aarholt, Thomas; Almeida Carvalho, Patricia; Sørby, Magnus Helgerud; Jensen, Ingvild Julie Thue; Guzik, Matylda N.; Norby, Truls Eivind; Haug, Halvard; Chatzitakis, Athanasios Eleftherios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Water photoelectrolysis has the potential to produce renewable hydrogen fuel, therefore addressing the intermittent nature of sunlight. Herein, a monolithic, photovoltaic (PV)-assisted water electrolysis device of minimal ...
  • Facet-engineered TiO2 nanomaterials reveal the role of water–oxide interactions in surface protonic conduction 
    Kang, Xiaolan; Chatzitakis, Athanasios; Aarholt, Thomas; Sun, Xinwei; Negri, Chiara; Norby, Truls (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Water adsorption and surface protonic conduction have been investigated at 25–400 °C in wet (H2O and D2O) atmospheres on nanocrystalline TiO2 hydrothermally grown to a predominance of different crystal facets. In situ ...
  • Galvanic restructuring of exsolved nanoparticles for plasmonic and electrocatalytic energy conversion 
    Kang, Xiaolan; Reinertsen, Vilde Mari; Both, Kevin Gregor; Galeckas, Augustinas; Aarholt, Thomas; Prytz, Øystein; Norby, Truls; Neagu, Dragos; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    There is a growing need to control and tune nanoparticles (NPs) to increase their stability and effectiveness, especially for photo- and electrochemical energy conversion applications. Exsolved particles are well anchored ...
  • Ni-doped A-site excess SrTiO3 thin films modified with Au nanoparticles by a thermodynamically-driven restructuring for plasmonic activity 
    Both, Kevin Gregor; Reinertsen, Vilde Mari; Aarholt, Thomas; Jensen, Ingvild Julie Thue; Neagu, Dragos; Prytz, Øystein; Norby, Truls; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Plasmonically active nanoparticles offer a promising pathway to extend the absorption range of photocatalysts. While not necessarily catalytically active themselves, these particles allow the absorption of lower energy ...
  • Single-step approach to sensitized luminescence through bulk-embedded organics in crystalline fluorides 
    Hansen, Per-Anders Stensby; Zikmund, Tomas; Yu, Ting; Kvalvik, Julie Nitsche; Aarholt, Thomas; Prytz, Øystein; Meijerink, Andries; Nilsen, Ola (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract Luminescent materials enable warm white LEDs, molecular tagging, enhanced optoelectronics and can improve energy harvesting. With the recent development of multi-step processes like down- and upconversion ...
