  • Two Co single crystal surfaces remain metallic up to 1 bar during Fischer-Tropsch synthesis. The observed intermediates support the carbide mechanism as the reaction pathway. By adding and removing CO we can follow the dynamics of the (dis)appearance of intermediates.

  • Using X-ray photoelectron spectroscopy, the surface composition of iron and ruthenium catalysts during ammonia synthesis at pressures up to 1 bar and temperatures as high as 723 K can be revealed.

  • To follow in situ and in real time how catalyst surfaces respond to gas composition changes is a challenge. This study reports on an eventaveraging method, based on cyclic gas pulsing and software-based image recognition, that overcomes the challenge for large photoelectron spectroscopy datasets.
