Unveiling the Role of Oxidation Debris on the Surface Chemistry of Graphene through the Anchoring of Ag Nanoparticles

摘要: The surface microchemical environment of graphene oxide (GO) has so far been oversimplified for understanding practical purposes. amount as well the accurate identification each possible oxygenated group on GO are difficult to describe not only due complex chemical nature oxidation reactions but also several intrinsic variables related production and processing GO-based materials. However, advance toward a more realistic description environment, it is necessary distinguish fragments with very peculiar characteristics that have treated simply oxide. In this way, small oxidized graphitic adsorbed surface, named debris or carboxylated carbonaceous (CCFs), here separated from commercially available GO. Spectroscopy microscopy results indicated these different By using dec...
