New for old: A novel catalytic combustion method to synthesize multiwalled carbon nanotubes (MWNTs, see SEM image) in situ in high yields from polypropylene as the carbon source in the presence of an organic‐modified clay and a supported nickel catalyst is reported. The method allows new high‐value MWNTs to be created from used polypropylene in an energy‐saving and environmentally friendly process.
Aus alt mach neu: Eine neuartige Methode zur katalytischen Verbrennung von Polypropylen liefert hohe Ausbeuten an mehrwandigen Kohlenstoffnanoröhren (MWNTs, siehe Rasterelektronenmikroskopie‐Bild) in Gegenwart eines mit organischen Gruppen modifizierten Tones und eines immobilisierten Nickelkatalysators. Der umweltverträgliche Prozess wandelt gebrauchtes Polypropylen in hochwertige MWNTs um.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
