The controlled etching of graphite and graphene by catalytic hydrogenation is potentially a key engineering route for the fabrication of graphene nanoribbons with atomic precision. In this study we exploit the benefits of aberrationcorrected high-resolution transmission electron microscopy to gain insight to the hydrogenation reaction as well as to identify the etching directions at the atomic scale.
