Preparation of different heteroatom doped graphene oxide based electrodes by electrochemical method and their supercapacitor applications

Production of chlorine-containing functional group doped graphene powders using Yucel's method as anode materials for Li-ion batteries

“…À to the graphene structure. 12,58,59 XPS results supported the formation of these different types of Cl-doped graphene-based powders.…”

“…In this context, the research on systems that store energy in chemical forms, such as rechargeable batteries (lead-acid batteries, redox ow batteries, lithium (Li)-ion batteries) and supercapacitors, has continues at an incredible pace. [4][5][6][7][8][9][10][11][12] Since lithium is the lightest metal, it is an extremely suitable candidate for use in rechargeable battery applications. This metal has been extensively researched for nearly half a century, and different Li-ion batteries with positive or negative electrodes consisting of lithium or lithium-containing compounds have been synthesized.…”

Single Step Electrochemical Semi‐Exfoliated S‐Doped Graphene‐Like Structures from Commercial Carbon Fiber as Efficient Metal‐Free Catalyst for Hydrogen Evolution Reaction

“…[59] Moreover, from the obtained spectrum, the vibrational groups of the SÀ GrOF1, which include carbonyl (C=O), aromatic (C=C), carboxyl (COOH), epoxy (CÀ OÀ C), and hydroxyl (OÀ H) groups, were distinctly observed. [60,61] The synthesis method in this work contributed to the conversion of carbon fibers into a graphitic form through the fractionation of disordered sp 2hybridized CÀ C bonds. [62] CF has a wide absorption band at 1050 cm À 1 , corresponding to the spectrum of the pure carbon fiber CÀ O stretching vibration.…”

Molecularly imprinted electrochemical aptasensor based on functionalized graphene and nitrogen-doped carbon quantum dots for trace cortisol assay

“…In order to enhance the performance of sensors, a variety of nanomaterials such as graphene, 18,19 carbon nanotubes, 20,21 carbon quantum dots 22 and metal nanoparticles 23 have been used as modification materials because of their high surface area and extraordinary physical, chemical and electronic properties. Graphene is a 2D carbon nanomaterial that shows the advantages of good electrical conductivity, large specific surface area and high mechanical strength.…”
