Limitations of CVD graphene when utilised towards the sensing of heavy metals

Unusual morphologies of reduced graphene oxide and polyaniline nanofibers-reduced graphene oxide composites for high performance supercapacitor applications

“…The CVD is one of the most popular, powerful and well controlled method to synthesize desired morphology and structures of graphene and/RGO. [1][2][3][4][5][6][7][8][9] But, the problem yet unresolved with CVD; yields poor quality of RGO and also shows low electrochemical performances. 3,5,10 Chemical methods were found to be economical and effective for producing RGO in large scale.…”

Therefore, chemical methods are more suitable for synthesizing high-performance RGO and RGO based composites.…”

Exploring the electrochemical performance of graphitic paste electrodes: graphene vs. graphite

“…2 However, modifying such surfaces has potential to leave underlying 'reactive' surfaces exposed, which can inuence and in certain cases dominate the observed electrochemistry. 2,9,17,18 Thus to overcome the earlier issue, researchers have recently turned to fabricating three-dimensional graphene architectures 15,16 or have utilised 'bulk' graphene in order to connect directly to it; for example, fabricating and utilising paste electrodes comprised primarily of the material in question. 19,20 Carbon based paste electrodes have been widely used and explored in electrochemistry since 1958 and generally offer benecial attributes over the more traditional electrodes, such as exhibiting low background currents, large potential domains and their ease of modication.…”

Effects of N doping and NH2grafting on the mechanical and wrinkling properties of graphene sheets

“…Graphene, a monolayer of sp 2 -bonded carbon atoms or one monolayer of graphite, 1 has a special one-atom thick two dimensional structure and possesses unique mechanical, 2 electrical, 3 thermal 4 and optical 5 properties. Their unique physical properties can have numerous potential applications in areas like nano-electromechanical systems (NEMS), 6 nanoelectronics, 7 sensors, 8 transistors, 9 batteries, 10 as well as nanocomposites. 11 Functionalizations by doping or grafting with other atoms or molecules are efficient ways to modify, manipulate or control the physical, chemical and mechanical properties of graphene sheets (GSs).…”
