摘要: Abstract Highly crystalline rhodium (Rh) nanoparticles supported on carbon nanotubes were prepared by selective oxidation method. Carbon and FeRh simultaneously generated in hydrogen arc plasma. The as-grown nanomaterials can be purified heat treatment open air soaking HCl. X-ray diffraction selected area electron results reveal that have a typical chemical CsCl-type structure which transformed into face-centered cubic thermal annealing the purification process. process is toward removal of amorphous coating nanoparticles, transforms Fe to Fe2O3. Fe2O3 easily dissolved hydrochloric acid, leaving nanotubes–Rh nanoparticles. Rh with diameters 2–60 nm are deposited uniformly surface nanotube bundles. This simple chemistry offers new for synthesizing controlling content nanotube–FeRh
