<jats:p> Au and Pt nanoparticles (NPs) were anchored on multiwalled carbon nanotubes (MWCNTs) via electron beam induced amorphous carbon encapsulation by energy-tunable MeV electron beam irradiation (MEBI) under ambient conditions. MEBI allowed the formation of size-homogeneous Au and Pt NPs on MWCNTs, as observed by transmission electron microscopy. Anchoring of metal NPs was achieved by MEBI-induced amorphous carbon encapsulation. The chemical doping effects of Au and Pt NPs were also verified by Raman spectroscopy. MEBI may provide a facile methodology for anchoring metal NPs to enhance electrical conductivity without destruction of MWCNTs. </jats:p>
