Özet
In recent years, nanostructures have attracted the attention of many scientists due to their unique properties. Many properties of nanostructures can be improved by changing the surface. For this purpose, multi-walled carbon nanotubes (MWCNTs) were covalently modified using Suzuki-cross coupling reactions with microwave-assisted synthesis. First, the MWCNTs were brominated. Aryl functionalized MWCNTs were synthesized from the reaction of brominated MWCNTs with aryl boronic acid derivatives in the presence of palladium catalyst. Synthesized compounds were characterized by the techniques of Fourier-Transform Infrared Spectroscopy, Nuclear Magnetic Resonance, Thermogravimetric Analysis and Transmission Electron Microscopy. The hydrogen storage properties of the synthetic compounds were determined. The example with the highest hydrogen storage capacity was N2 and its hydrogen storage capacity was determined as 0.45 wt%. The hydrogen storage capacity of functionalized MWCNTs was consistent with the results of carbon nanomaterials in the literature.
