In recent times, nanostructures have attracted the eye of many scientists as a consequence of their distinctive properties. Many properties of nanostructures may be improved by altering the floor. For this goal, multi-walled carbon nanotubes (MWCNTs) had been covalently modified utilizing Suzuki-cross coupling reactions with microwave-assisted synthesis. First, the MWCNTs had been brominated. Aryl functionalized MWCNTs had been synthesized from the response of brominated MWCNTs with aryl boronic acid derivatives within the presence of palladium catalyst. Synthesized compounds had been characterised by the strategies of Fourier-Remodel Infrared Spectroscopy, Nuclear Magnetic Resonance, Thermogravimetric Evaluation and Transmission Electron Microscopy. The hydrogen storage properties of the artificial compounds had been decided. The instance with the best hydrogen storage capability was N2 and its hydrogen storage capability was decided as zero.45 wt%. The hydrogen storage capability of functionalized MWCNTs was per the outcomes of carbon nanomaterials within the literature.
