摘要： Graphene is considered a new member of the carbon materials family. Graphene is made solely of monolayers of sp2 hybridized carbon atoms densely ordered in a honeycomb crystal lattice, from which graphitic materials of various dimensions, e.g., zero-dimensional (0D) fullerenes, 1D nanotubes, and 3D graphite, can be built up. Graphene exhibits diverse electronic, thermal, and optical properties, including significant carrier mobility at room temperature (z10,000 cm2 V(cid:1)1 s(cid:1)1), theoretical specific surface area as high as 2630 m2 g(cid:1)1, and Young’s modulus as high as 1 TPa, along with superior thermal conductivity as high as 3000e5000 W mK(cid:1)1, resulting in its diverse potential applications in various fields such as chemical sensors, electronic devices, energy storage and conversion, catalysts, etc. Numerous endeavors have been being made to develop versatile and dependable physical and chemical fabrication techniques for the synthesis of graphene and its derivatives. So far, extensively utilized techniques, including chemical vapor deposition, epitaxial growth, thermal annealing approaches, the arc-discharge strategy, etc., have been successfully employed for the synthesis of graphene nanosheets (GNs) possessing great quality, mass production ability, and cost efficiency [1].
