Active sites for the oxygen reduction reaction in nitrogen-doped carbon nanofibers
Buan, Marthe Emelie Melandsø; Cognigni, Andrea; Walmsley, John; Muthuswamy, Navaneethan; Rønning, Magnus (Peer reviewed; Journal article, 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 ... -
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 ...
