Description:
(abstract)We report that iron-catalyzed graphitization occurs via a new type of mechanism called homogeneous solid-state catalysis. We use dark field in situ transmission electron microscopy to demonstrate that crystalline iron nanoparticles ‘burrow’ through amorphous carbon to generate multi-walled graphitic nanotubes. The process is remarkably fast, particularly given the solid phase of the catalyst, and we use in situ synchrotron X-ray diffraction to demonstrate that graphitization is complete within a few minutes.
