Abstract

original image

The cover picture shows an illustration of a graphene sheet decorated with different types of oxygen functionalities and the oxidative dehydrogenation reaction of isobutane to isobutene that is catalyzed by the functionalized edge sites. The micrograph background image is of the same graphenes recorded by Schwartz et al using a new helium-ion microscope at the Center for Nanophase Materials Sciences/Oak Ridge National Laboratory (CNMS/ORNL). The application of oxygen-modified graphene for gas-phase reactions, which is reported on page 840, is a new approach to study the scarcely explored field of carbon catalysis. This field of metal-free carbon-based catalysis is of importance for developing a more sustainable and environmentally friendly catalytic oxidative dehydrogenation process as carbon materials can be easily disposed of after their lifetime.
