Carbon encapsulated nickel nanoparticles synthesized by a modified alcohol catalytic chemical vapor deposition method

Carbon encapsulated nickel nanoparticles synthesized by a modified alcohol catalytic chemical vapor deposition method

In this work, a simple and cost-efficient method was demonstrated for the production of carbon encapsulated nickel nanoparticles (CENPs). The CENPs were synthesized from nickel oxide by a modified alcohol catalytic chemical vapor deposition method at atmospheric pressure. Structural characterization...
