Statistical-Raman-Microscopy and Atomic-Force-Microscopy on Heterogeneous Graphene Obtained after Reduction of Graphene Oxide
Siegfried Eigler, Ferdinand Hof, Michael Enzelberger-Heim +3
Graphene oxide can be used as a precursor to graphene but the quality of graphene flakes is highly heterogeneous. Scanning-Raman-Microscopy (SRM) is used to characterize films of g…
Chemistry with Graphene and Graphene Oxide - Challenges for Synthetic Chemists
Siegfried Eigler, Andreas Hirsch
The chemical production of graphene as well as its controlled wet- chemical modification is a challenge for synthetic chemists and the characterization of reaction products require…
Investigation of the Thermal Stability of the Carbon Framework of Graphene Oxide
Siegfried Eigler, Stefan Grimm, Andreas Hirsch
In this study, we use our recently prepared graphene oxide (GO) with an almost intact σ-framework of C-atoms (ai-GO) to probe the thermal stability of the carbon framework for the…
Basic Insights into Tunable Graphene Hydrogenation
Ricarda A. Schäfer, Daniela Dasler, Udo Mundloch +2
The hydrogenation and deuteration of graphite with potassium intercalation compounds (GICs) as starting materials was investigated. Characterization of the reactions products (hydr…
Polyhydrogenated Graphene - Excited State Dynamics in Photo- and Electroactive 2D-Domains
Volker Strauss, Ricarda A. Schäfer, Frank Hauke +2
Understanding the phenomenon of intense photoluminescence in carbon materials such as hydrogenated graphene, graphene nanoribbons, etc. is at the forefront of investigations. In th…
Novel λ^3-Iodane Based Functionalization of Synthetic Carbon Allotropes (SCAs) - Common Concepts and Quantification of the Degree of Addition
Ferdinand Hof, Ricarda A. Schaefer, Cornelius Weiss +2
The covalent functionalization of carbon allotropes represents a main topic in the growing field of nano materials. However, the development of functional architectures is impeded…
