Synthesis and Modification of Carbon Nanomaterials utilizing Microwave Heating

Abstract

Microwave-assisted synthesis and processing represents a growing field in materials research and successfully entered the field of carbon nanomaterials during the last decade. Due to the strong interaction of carbon materials with microwave radiation, fast heating rates and localized heating can be achieved. These features enable the acceleration of reaction processes, as well as the formation of nanostructures with special morphologies. A comprehensive overview is provided here on the possibilities and achievements in the field of carbon-nanomaterial research when using microwave-based heating approaches. This includes the synthesis and processing of carbon nanotubes and fibers, graphene materials, carbon nanoparticles, and capsules, as well as porous carbon materials. Additionally, the principles of microwave-heating, in particular of carbon materials, are introduced and important issues, i.e., safety and reproducibility, are discussed.

Microwave energy-based synthesis and characterisation of hollow carbon nanospheres decorated with carbon nanotubes or metal oxide nanowires

“…Instead, these NWs exhibit a pearl necklace-like morphology that is composed of adjacent NPs encapsulated within graphitised carbon layers. [8,26,35,50,51] Based on the measurements taken, such NPs' diameter size distribution ranges between 30-100 nm. After the morphological property characterisation of the as-prepared MONW/HCNS composite was completed, its elemental composition was also investigated by using EDX analysis.…”

Carbon Dots with Tunable Photoluminescence Properties

“…[11] Microwave-assisted synthesis and modification of carbon nanomaterials has been explored due to carbon materials strong interaction with microwave radiation. [12] Microwave represent energy-saving and time-saving strategy for carbon dots synthesis. Other common methods for carbon dots like hydrothermal often requires several hours or days, high temperature and high pressure.…”

Recent Advances in Effective Reduction of Graphene Oxide for Highly Improved Performance Toward Electrochemical Energy Storage

“…[92] Also, many studies adopted the microwave-irradiation method for large-scale production of high-quality graphene from GO. [93,94] Relative to the large consumption of energy in high-temperature annealing (>1000°C), microwave-assisted heating is an efficient method or expansion and reduction of precursors prepared by the (modified) Hummers method into microwave-exfoliated graphite oxide (MEGO).…”
