Atomic-scale Monitoring of Carbon Nanofiber Growth in Steam Reforming Catalysts

Atomic-scale Monitoring of Carbon Nanofiber Growth in Steam Reforming Catalysts 

Although the HRTEM movies provide important information about the atomic-scale surface dynamics, they capture only the result of the atomic diffusion events and not directly the individual atomic displacements. To understand the origin of the transport mechanisms, the observations have been complemented with results based on DFT calculations. The calculations show that step edges facilitate methane dissociation and that carbon atoms bind more strongly to step edges than
