%X Multi-walled carbon nanotubes (MWCNTs) are known by their high active area, high electrical conductivity and chemical stability. These properties can promote better ions transportation, facilitating the double layer charging. MWCNTs unzipping process is an interesting alternative to improve capacitive behavior and surface area. In this work we report on the synthesis and electrochemical properties of unzipped carbon nanotubes. MWCNTs were obtained by thermal chemical vapor deposition. The unzipping process was carried out in a microwave chemical vapor deposition reactor. SEM micrographs showed graphene sheets presence. In Raman spectra, we notice an increase in D band intensity caused by carbon nanotubes unzipping. By analyzing X-ray diffraction patterns, we noticed a peak at 10° related to graphene oxide. We also observed the decrease in (002) peak intensity. Further, hydrogen plasma showed itself to be a promising alternative for graphene obtainment.
