Facile synthesis of silver nanoparticles supported on three dimensional graphene oxide/carbon black composite and its application for oxygen reduction reac... A 3D graphene oxide/carbon sphere supported silver composite (Ag/GO/C) was synthesized using graphene oxide as the reducing agent. The reducing...
40d [416]. The graphene under and around the Cu NPs will be dissociated by the Cu NPs and then reacted with H2 to form methane through the local catalytic hydrogenation of carbon, leaving plenty of hole rims around the Cu NPs. After removing the Cu NPs, the GNM is formed. In these ...
That does not work with HOPG (Highly Oriented Pyrolytic Graphite) or carbon black (graphite powder). The permeability which affects chemistry and surface science applications is certainly related to graphene's unique electronic properties. Obviously, given how well Nafion based technology is established...
(vs. SCE) gives high background current and clear quinone type of redox couple around 0.3–0.4V (vs. SCE)110–130F/gElectrode material was a paste composed of CR-GO, acetylene black and polyvinylidene difluoride with weighted ratio of 7:21. No information about nitrogen or argon purging. ...
The XRD results of different Ca-adsorbed samples were almost the same as that of pure carbon black, disclosing no corresponding diffraction peak of Ca nanoparticles (Fig. 6d), which are consistent with AC-HAADF-STEM images and XPS results, indicating the successful preparation of various doped-...
It is well accepted that GO has a structure of smallsp2C–C domains isolated within thesp3C–O matrix1,2,3. Raman spectroscopy provides a powerful tool to obtain the detailed structural information of graphene-based materials. The G peak is attributed to bond stretching ofsp2carbon pairs, and...
prepared GDs by oxidation of the carbon black in nitric acid under reflux conditions overnight. After cooling and centrifugation, Nanomaterials 2016, 6, 157 8 of 20 Nanomaterials 2016, 6, 157 8 of 20 Carbon black has also been used as a carbon source. Chen et al. prepared GDs by ...

This research used flash joule heating to turn carbon black and other industrial byproducts into graphene. This material is chemically stable and can be produced with as little as one teaspoon of graphite powder. It can also be obtained from scrap metal or wood. It is important to note that...
from the University of Manchester, Andre Geim and Konstantin Novoselov, discovered a novel carbon-based nanoparticle called graphene for which they received the Nobel Prize for Physics in 2010. In order to produce graphene, you start with graphite, and then peel off a single layer of carbon ...
