“…21 All these processes are not a low temperature process as the plasma is an arc discharge. Other attempts include APPJ treatment of graphene to increase hydrophilicity 22 and introduction of bandgap at an input power of 150 W. 23 In this study it will be shown that a APPJ can be used as tool for controlled doping graphene oxide. Kelvin probe force microscopy (KPFM) was used to depict any changes in electronic properties of these plasma functionalised GO films.…”

“…Also, a change in the ratio of 2D to G is observed ( Figure A6 ). Lee et al [ 28 ] obtained I 2D / I G ≈ 2.94 and 0.39 for monolayer and multilayer graphene, respectively. Terasawa et al have found that I 2D / I G was decreasing with increasing nitrogen content, whereas I D / I G was more or less constant [ 16 ].…”

Methods for synthesizing nitrogen-doped graphene-like materials have attracted significant attention among the scientific community because of the possible applications of such materials in electrochemical devices such as fuel cells, supercapacitors and batteries, as well as nanoelectronics and sensors. The aim of this paper is to review recent advances in this scientific niche. The most common synthesis technique is nitridization of as-deposited graphene or graphene-containing carbon mesh using a non-equilibrium gaseous plasma containing nitrogen or ammonia. A variety of chemical bonds have been observed, however, it is still a challenge how to ensure preferential formation of graphitic nitrogen, which is supposed to be the most favorable. The nitrogen concentration depends on the processing conditions and is typically few at.%; however, values below 1 and up to 20 at.% have been reported. Often, huge amounts of oxygen are found as well, however, its synergistic influence on N-doped graphene is not reported. The typical plasma treatment time is several minutes. The results reported by different authors are discussed, and future needs in this scientific field are summarized. Some aspects of the characterization of graphene samples with X-ray photoelectron spectroscopy and Raman spectroscopy are presented as well.

“…However, low uniformity, aggregation, and dissolution of active Au metal are still the critical issues due to low interactions between metal and the hydrophobic GR. In efforts to solve these issues, some approaches, such as acid treatment, oxygen plasma treatment, and heteroatom doping process, have been employed to enhance hydrophilic feature of 3D-GF [19][20][21][22]. However, the complicated procedure, high cost, and low efficiency rather limited their applications.…”

The electrochemical sensing performance of metal-graphene hybrid based sensor may be significantly decreased due to the dissolution and aggregation of metal catalyst during operation. For the first time, we developed a novel large-area high quality three dimensional graphene foam-incorporated gold nanoparticles (3D-GF@Au) via chemical vapor deposition method and employed as free-standing electrocatalysis for non-enzymatic electrochemical glucose detection. 3D-GF@Au based sensor is capable to detect glucose with a wide linear detection range of 2.5 μM to 11.6 mM, remarkable low detection limit of 1 μM, high selectivity, and good stability. This was resulted from enhanced electrochemical active sites and charge transfer possibility due to the stable and uniform distribution of Au NPs along with the enhanced interactions between Au and GF. The obtained results indicated that 3D-GF@Au hybrid can be expected as a high quality candidate for non-enzymatic glucose sensor application.
