- Abstract
The cobalt K‐edge X‐ray absorption near‐edge structure of a cobalt carbide compound, synthetized under in‐situ conditions, has been determined by using laboratory‐based and synchrotron‐based X‐ray absorption spectroscopy. We have carburized pure cobalt metal in‐situ, avoiding all adverse effects of metal‐support interactions as well as any degradation of the cobalt carbide formed. A non‐negative matrix factorization was applied to determine the features of the spectrum of cobalt carbide, highly needed to identify this phase in an unambiguous manner in cobalt‐based Fischer‐Tropsch catalysts.
