Absorbing Manganese Oxide on Multi-Walled Carbon Nanotubes
A layer of Manganese dioxides (γ-MnO2) was absorbed upon carbon nanotubes (CNTs) surface by using a chemical deposit process. The morphologies of the MnO2/CNTs composite were characterized using transmission electron microscopy (TEM), energydispersive X-ray spectrometry (EDS), X-ray diffraction (XRD) and laser Raman spectroscopy (RS). It is found that absorbed layer belongs to the γ-MnO2 nanoparticles in size about 10 nm, and coated homogeneously around the CNTs. It is expected that this MnO2/CNTs composite will be widely applied to make supercapacitors.
