Abstract

original image

Structured catalyst: A new strategy was used to produce carbon nanotube monoliths by a solid-phase process that was well characterized by in situ techniques. The synthesized spherical nanoparticles display extremely high selectivity in the oxidative dehydrogenation (ODH) of ethylbenzene (see scheme).
