Nitrogen-Doped Carbon Nanotubes as an Effective Support of Heterogeneous Catalysts for Selective Alkene Oxidation
Nitrogen-doped carbon nanotubes (N-CNTs) with different degrees of nitrogen doping were synthesized. The effects of nitrogen in the N-CNTs on the hydrophilic–hydrophobic properties of carbon nanotubes and their activity in the decomposition of Н 2 О 2 were studied. Various approaches to the surface...
