Abstract
Abstract In this report, we demonstrate a novel two-step approach that is capable of growing uniform high-concentration MoS2 nanoflakes on the carbon nanotube (CNT) sheet substrate. The CNT sheet is simply activated by the oxygen plasma to separate large CNT bundles and to create more active surface sites. A typical chemical vapor deposition (CVD) process is employed, enabling the direct growth of MoS2 nanoflakes on the activated CNT substrate. Morphologies and structures of MoS2/CNT nanohybrid are characterized by SEM/EDS, high-resolution TEM (HRTEM) and Raman spectroscopy. Our results suggest that the plasma treatment of CNT sheet is critical to obtain well-dispersed large quantity of MoS2 nanoflakes on CNT assemblies.
