    • An In Situ XAS Study of the Cobalt Rhenium Catalyst for Ammonia Synthesis 

      Mathisen, Karina; Kirste, Karsten Granlund; Hargreaves, Justin S. J. (Journal article; Peer reviewed, 2018)
      A cobalt rhenium catalyst active for ammonia synthesis at 400 °C and ambient pressure was studied using in situ XAS to elucidate the reducibility and local environment of the two metals during reaction conditions. The ...

    • COx-free hydrogen production from ammonia – mimicking the activity of Ru catalysts with unsupported Co-Re alloys 

      Kirste, Karsten Granlund; McAulay, Kate; E. Bell, Tamsin; Stoian, Dragos; Laassiri, Said; Hargreaves, Justin S. J.; Mathisen, Karina; Torrente-Murciano, Laura (Peer reviewed; Journal article, 2020)
      On-demand production of hydrogen from ammonia is a challenge limiting the implementation of ammonia as a long term hydrogen vector to overcome the difficulties associated with hydrogen storage. Herein, we present the ...

    • XAS investigation of silica aerogel supported cobalt rhenium catalysts for ammonia decomposition 

      Kirste, Karsten Granlund; Laassiri, Said; Hu, Zhigang; Stoian, Dragos; Torrente-Murciano, Laura; Hargreaves, Justin S. J.; Mathisen, Karina (Peer reviewed; Journal article, 2020)
      The implementation of ammonia as a hydrogen vector relies on the development of active catalysts to release hydrogen on-demand at low temperatures. As an alternative to ruthenium-based catalysts, herein we report the ...
