Ni-promoted synthesis of graphitic carbon nanotubes from in situ produced graphitic carbon for dehydrogenation of ethylbenzene†
Abstract
Graphitic carbon nanotubes (GCNTs) were fabricated from in situ produced graphitic carbon by calcining biomass/melamine/Ni(NO3)2·6H2O. Ni-based hybrids (NiOx@GCNTs) displayed superior catalytic capacity in direct dehydrogenation of ethylbenzene. The specific reaction rate can reach up to 8.1 μmol m−2 h−1, and unprecedented stability was obtained over 165 h without any activation process.
