THE INFLUENCE OF GAS ADMIXTURES ON THE SYNTHESIS OF GRAPHENE NANOSHEETS IN ARGON MICROWAVE PLASMA TORCH DISCHARGE
Original language description
In this work possibility of the synthesis of two-dimensional graphene nanosheets in gas phase was studied. We used microwave plasma torch discharge (2.45 GHz, 210 W) operating at atmospheric pressure conditions to synthesize carbon nanosheets with rectangular shape and typical size of hundreds of nanometres. The torch discharge was ignited in argon flowing through the central channel of the nozzle. Liquid ethanol, whose vapours were led to the discharge by carrier gas - argon, was selected as a precursor. The mixture of ethanol vapour, argon and oxygen or hydrogen was introduced to the discharge through outer channel of the nozzle. Decomposition of ethanol vapours, at specific deposition conditions, led to the synthesis of graphene nanosheets. The synthesized material was collected on the silicon substrate placed in the sample holder situated few centimetres above the discharge. The influence of different amount of oxygen or hydrogen in the gas mixture on the properties of synthesised graphene nanosheets was investigated. Such prepared samples were analysed by scanning electron microscopy, Raman spectroscopy and energy-dispersive X-ray spectroscopy (EDX). The discharge was examined using optical emission spectroscopy.
