• Popis: Influence of the interplay between central (Q C ) and secondary (Q S ) channel gas flow as well as delivered microwave power (P MW ) during graphene nanosheets synthesis in microwave plasma was investigated. Argon was used as a working gas as well as a carrier gas for ethanol precursor. In dual channel configuration, plasma discharge can be sustained even at high flow rates of ethanol due to the separation of working and carrier gas. Depending on the Q C , Q S flow rates and delivered microwave power, high quality carbon nanostructures with controlled properties were prepared.
