Active sites for the oxygen reduction reaction in nitrogen-doped carbon nanofibers
Buan, Marthe Emelie Melandsø; Cognigni, Andrea; Walmsley, John; Muthuswamy, Navaneethan; Rønning, Magnus (Journal article; Peer reviewed, 2019)Understanding the role of iron and the nature of the active sites in nitrogen-doped carbon nanomaterials is vital for their future application as oxygen reduction electrocatalysts in fuel cells. In this paper, porphyrin-like ... -
Identification of carbon species on iron-based catalysts during Fischer-Tropsch synthesis
Pena, Diego; Cognigni, Andrea; Neumayer, Thomas; Van Beek, Wouter; Jones, Debra; Quijada, Melesio; Rønning, Magnus (Journal article; Peer reviewed, 2018)This paper focuses on the use of in situ and ex situ characterisation techniques to provide evidences of carbon species on a commercial iron-based Fischer-Tropsch synthesis catalyst as well as other indices of potential ... -
The Effect of Copper Loading on Iron Carbide Formation and Surface Species in Iron‐Based Fischer–Tropsch Synthesis Catalysts
Pena, Diego; Jensen, Lise Saue; Cognigni, Andrea; Myrstad, Rune; Neumayer, Thomas; Van Beek, Wouter; Rønning, Magnus (Journal article; Peer reviewed, 2018)The effect of copper as promoter on iron carbide formation and the nature of surface species on iron‐based catalyst during Fischer–Tropsch synthesis (FTS) was investigated. Iron‐based catalysts (15 wt % of Fe) supported ...
